Manual and machine forming of sheet and sections — Planning and preparation

Introduction

Manual and machine forming of sheet and sections — Planning and preparation is a vocational learning module for learners in Blacksmithing, artistic metalwork, architectural metalwork and related craft-fabrication settings. It focuses on the decisions that must be made before a sheet, strip or section is formed by hand or by machine: interpreting the job, checking the material, selecting a suitable process, planning the bend or forming sequence, preparing tools and equipment, controlling risk, and deciding how quality will be checked.

Selected jurisdiction: United Kingdom — England. Occupational-safety references in this course use the Health and Safety Executive framework that applies in England as part of Great Britain. The vocational pathway reference is explicitly England-specific. This course does not state that laws, qualifications, standards, job titles or certification are automatically equivalent in Scotland, Wales, Northern Ireland or any other country.

Authority and supervision rule: Official rules, current legislation, manufacturer instructions, employer risk assessments, safe systems of work, machine-specific training and workplace instructions always take precedence over this learning resource. You must not operate a press brake, guillotine, powered rolls, power hammer, press, forge or other hazardous equipment from this course alone. Hazardous practical work is only for learners who are authorised, trained and appropriately supervised in a suitable workplace or training workshop.

Steel sections supplied as stock. Before forming, identify the section, material specification, dimensions, condition and orientation rather than relying on appearance alone.

An angle section is one example of a supplied profile. Section geometry affects where a bend, twist or curve can be introduced without unacceptable distortion.

Learning Outcomes

By the end of this module, you should be able to explain and demonstrate, under suitable supervision, how to:

Job planning: Extract dimensions, tolerances, material information, finish requirements and forming notes from a drawing, template, sample or work instruction.
Material identification: Confirm the correct sheet, strip or section before work begins and recognise when missing information must be escalated.
Process selection: Distinguish manual forming from machine forming and choose a process that is appropriate to the workpiece, required geometry, quality requirement and authorised equipment.
Bend planning: Use datum lines, bend lines, bend allowance, bend deduction, inside radius, springback and bend sequence as planning concepts.
Workshop safety: Identify forming hazards, apply the hierarchy of control and follow machine-specific safeguards and safe systems of work.
Quality control: Plan a first-off check and decide how angles, dimensions, radii, twist, surface condition and repeatability will be verified.
Sustainable manufacturing: Plan stock use, nesting, rework prevention, segregation of scrap and responsible use of consumables.

Why Planning Matters

Forming changes the geometry of metal by controlled plastic deformation. The operation may look simple, but the quality and safety of the result depend heavily on preparation. A misplaced datum, unidentified material, unsuitable tooling, incorrect bend sequence or poorly planned workpiece movement can create scrap, rework, damage or hazardous conditions.

In blacksmithing and artistic metalwork, forming may combine craft judgement with drawings, templates, jigs and machine processes. The current Skills England Blacksmith occupational standard describes the occupation as using craft, art or skill to design, shape and join metal by hot forging and other metalworking processes for bespoke, small-batch and heritage work. It also expects technical interpretation, planning, process selection, safe preparation of tools and materials, quality focus and safe use of hand and mechanical tools.^[1]

Authentic Workshop Context: Chain and Architectural Metalwork

A blacksmith preparing a run of decorative links, scrolls, brackets or railing components may need to move repeatedly between stock preparation, hand forming, jigs, forging equipment and fabrication processes. The sequence must preserve dimensions and visual rhythm while allowing safe handling and efficient use of material. Historic chain making in the Black Country also illustrates how repeated forms depend on consistent stock, controlled sequence and practiced inspection.

Core Concepts for Planning Forming Work

Sheet, Strip, Bar and Section

Sheet is flat material supplied in a specified thickness. Strip is a comparatively narrow flat product. Bar is solid stock supplied in forms such as flat, round or square. Section or profile refers to a shaped cross-section such as angle, channel or other structural or decorative section. Practitioners may also use the word stock for material held for future jobs.

Before planning a forming operation, confirm the material identity from reliable job information. Relevant details may include grade or specification, thickness or section size, temper or condition, coating, surface finish, grain or rolling direction where relevant, length, heat or batch identification where required, and any restrictions in the drawing or material data. Never substitute an unknown grade because two pieces look similar.

Forming, Bending and Forging

Forming is a broad term for changing shape without principally removing material. Bending produces an angle or curve by deforming the workpiece about an axis or over a former. Forging shapes metal using compressive force, commonly while the metal is hot in blacksmithing, although some processes are cold. The planning principles overlap, but the hazards, equipment, temperatures and material response may differ substantially.

This module concentrates on planning for sheet and section forming. It does not provide stand-alone operating instructions for hot forging or powered machinery.

Manual metalworking relies on controlled workholding, suitable tooling and clear communication. A photograph can show posture and tool relationships, but the current workshop method statement takes precedence.

Bend Geometry and Terminology

A drawing may specify an included angle, outside dimensions, inside dimensions, an inside radius, a bend line, or a combination of these. When sheet is bent, material on the outside of the bend stretches while material toward the inside is compressed. Somewhere between these regions is a zone often described using a neutral axis model.

For planning and development work, practitioners use terms such as bend allowance, bend deduction and springback. Bend allowance relates to the length of the neutral-axis portion through a bend used when developing the flat blank. Bend deduction is a practical development value used to obtain the required finished dimensions. Springback is the elastic recovery that occurs after forming force is removed.

These values are not universal constants. They depend on material, condition, thickness, radius, tooling and process. Use approved workshop data, verified calculation methods, manufacturer information, trials authorised by the workplace and first-off inspection. Do not transfer a press-brake setting from one material or machine to another without verification.

Datum, Bend Line and Reference Edge

A datum is an agreed reference from which dimensions are established. A bend line indicates the intended bend location on the blank or in the drawing. A reference edge is a reliable edge used for marking, measuring, locating against a stop or checking a part. Good planning reduces the number of times dimensions are chained from previously formed features.

When possible, plan measurements from stable datums and note which face is the reference face. For artistic work based on a template, the template itself may be a controlled reference, but it should be labelled and protected from distortion.

Bend Sequence

The order of bends or forming operations can determine whether a part can be held, supported and removed safely and whether later operations remain accessible. Sequence planning should consider:

Which datum must remain available for later measurement.
Whether an earlier bend will obstruct tooling, backgauges, stops or handling.
How the workpiece centre of gravity and free end will move.
Whether two adjacent bends create a trapped or enclosed shape.
When a first-off dimensional check is most useful.
Whether surface protection or orientation must be preserved.

A good sequence is not merely the shortest sequence. It is a sequence that is safe, repeatable, inspectable and compatible with the authorised process.

Manual and Machine Forming Methods

Manual Forming

Typical manual or primarily hand-controlled forming resources in a craft metalwork workshop may include a vice with suitable jaws, bending forks, scrolling tools, stakes, formers, bending bars, hammers and mallets, swage blocks, jigs, templates and an English wheel. Their safe use still requires competent instruction, secure workholding, appropriate space and control of pinch, strike and sharp-edge hazards.

An English wheel with interchangeable lower rollers. Tool selection and pressure are material- and task-dependent and must be taught in the workshop.

Manual forming can be valuable for one-off artistic work, adjustment, flowing curves and small components. It can also create variability if datum control, templates, force application and inspection are inconsistent. Planning should make the intended form measurable rather than relying only on visual judgement.

Machine Forming

Machine forming can include sheet-metal folders, press brakes, powered rolls, section rolls, presses and other equipment. A machine may improve repeatability and productivity, but it introduces machine-specific hazards and capacities that must be managed under workplace controls.

Tools, Equipment and Measuring Resources

Use only equipment you are authorised and trained to use. A planning sheet should name the required resources rather than leaving them to be improvised after work begins.

Resource	Typical planning purpose	Checks before use
Steel rule, tape measure and callipers	Linear dimensions, stock verification and finished size	Suitable range, readable scale, condition and any required calibration status
Engineer's square and straightedge	Squareness, reference edges and alignment	Clean faces, undamaged edges and known accuracy
Scriber, chalk or approved marker	Layout and identification	Marking method permitted for the material and finish
Centre punch or prick punch	Durable location marks where permitted	Drawing and surface-finish requirements allow indentation
Angle gauge or protractor	Bend-angle checking	Correct range, clean contact faces and suitable accuracy
Radius gauge or template	Radius checking	Correct nominal radius and identifiable template
Workshop template	Comparing a curve, scroll or repeated artistic form	Labelled, undamaged and made from a stable reference
Vice, bending fork, stake or former	Manual forming and work support	Secure mounting, suitable size, sound condition and safe work area
Sheet-metal folder	Straight sheet bends	Authorised machine, correct capacity and safeguards, following workplace instructions
Press brake	Controlled sheet bending	Authorised machine, suitable tooling and capacity, guards and protective devices, following machine-specific checks
Rolls or section rolls	Curving sheet, bar or sections	Correct roll arrangement, capacity and authorised setup
Jig, stop or backgauge	Repeatable location	Secure, correct datum, no unsafe interference with workpiece movement

Materials and Forming Behaviour

In artistic metalwork and blacksmithing you may encounter low-carbon steel, stainless steel, aluminium alloys, copper alloys and other materials. The same nominal thickness in two materials does not imply the same forming force, springback or minimum suitable radius. Condition also matters: work-hardened, heat-treated, coated or previously formed stock can behave differently from untreated stock.

Before work starts, check the drawing, material certificate or purchasing information where available, stock labels, workplace material system and supervisor instruction. If identification is uncertain, quarantine or set aside the material and resolve the uncertainty before forming.

Coatings, lubricants, metalworking fluids and residues may introduce substance hazards. HSE notes that engineering hazards can include dusts from cutting or shaping, welding and cutting fumes, metalworking-fluid mists, lubricants, adhesives, paints and degreasers; controls are selected through assessment and may include extraction, respiratory protection, fluid maintenance and health surveillance.^[2]

Planning Workflow

A professional forming plan connects job information to a controlled workshop sequence.

Planning stage	Questions to answer	Evidence to record
Job clarification	What is being made, for whom and to which drawing, template, sample or specification?	Job number, drawing revision, quantity, deadline and authorised instructions
Material verification	Is the stock definitely the required grade, size, condition and finish?	Material identity, dimensions and any traceability reference
Forming definition	Which angles, radii, curves, twists or transitions are required?	Marked-up drawing, template or operation sketch
Process selection	Is manual forming, folding, press braking, rolling or another authorised process most suitable?	Chosen process and reason
Tooling and equipment	Which tools, formers, dies, jigs, supports and measuring devices are needed?	Resource list and machine/tooling compatibility check
Sequence	In which order will features be formed, measured and adjusted?	Numbered operation route or annotated sketch
Risk control	What can harm people, and what controls are required before starting?	Workplace risk assessment, method statement or safe system references
First-off check	Which dimensions and visual criteria must be accepted before repetition?	Inspection points, measuring method and acceptance criteria
Batch or one-off control	How will repeatability or artistic consistency be maintained?	Jig/template references, checkpoints and sign-off
Close-out	How will parts, scrap, tooling and records be handled?	Identification, segregation, storage and job record

Step-by-Step Demonstration: Planning a Simple 90-Degree Sheet Bend

Purpose: This is a planning demonstration, not stand-alone press-brake operating instruction. The learner may prepare documentation and observe an authorised operator. Any practical forming must be carried out only by a trained and authorised person under the workplace safe system and suitable supervision.

Imagine a small low-carbon-steel bracket is required from sheet. The drawing specifies one straight bend, a finished 90-degree angle, a stated inside radius, flange dimensions and a tolerance.

Read the current drawing. Check the job number, revision, material specification, thickness, finish, finished dimensions, bend angle, inside radius, tolerances and quantity.
Clarify missing information. If the material, radius, tolerance or datum is unclear, stop the planning process and obtain authorised clarification rather than assuming.
Verify the stock. Confirm material identity, thickness, surface condition and sufficient blank size using the workplace material-identification system.
Choose a datum. Mark on the planning sketch which edge and face will control the flange dimensions and inspection.
Determine the development method. Use the workplace-approved bend allowance or bend-deduction method and verified material/tooling data to establish the blank dimension; record the source of the value.
Select the authorised process. Decide whether the work is suitable for the available folder, press brake or another approved process, considering capacity, required radius, quality and repeatability.
Identify suitable tooling without setting it. Record the punch, die or former requirement from approved machine/tooling information. Do not invent clearances, force or tonnage from this course.
Plan the bend orientation and workpiece movement. Sketch the blank before and after bending, including which flange moves and where support is needed. Identify pinch, crush and unexpected-movement zones.
Plan the safeguards and pre-use checks. Reference the machine-specific checklist, guards or protective devices, control mode, isolation requirements where applicable, and the authorised safe system of work.
Plan first-off inspection. Specify how the finished 90-degree angle, flange dimensions, radius, twist, surface marking and burr condition will be checked.
Authorised forming and inspection. Under the workplace method, the authorised operator produces the first-off part; the part is made safe to handle and inspected against the drawing before repetition.
Record and release. Record the accepted setup or job data according to workplace procedure. If the first-off part is outside tolerance, stop repetition, diagnose the cause and obtain approval for any correction.

Risk Controls and Safe Preparation

Risk-Assessment Method

For work in England, HSE describes a practical risk-management process: identify hazards, assess the risks, control the risks, record significant findings where required, and review controls.^[3] The workplace assessment must reflect the actual machine, material, task, people and environment.

The hierarchy of control should be applied before relying on PPE. HSE states that PPE is a last resort after consideration of elimination, substitution, engineering controls and administrative controls.^[4]

Hazard during planning or forming	Examples	Planning controls to confirm
Crushing and trapping	Closing tools, moving ram, rollers, pinch points, workpiece motion	Prevent access to danger zones using the machine's engineered safeguards; verify authorised mode, guards and protective devices; plan hand positions and supports; never bypass an interlock
Unexpected movement	Long sheet lifting during a bend, springback, rotating section, stored energy	Plan workpiece path, supports, exclusion area, communication and controlled release; keep others clear
Sharp edges and burrs	Cut sheet, cropped strip, fresh sheared edge	Approved handling method, deburring stage where specified, suitable gloves only where risk assessment and machine rules permit
Manual handling	Large sheets, long bars, awkward frames	Avoid hazardous manual handling where reasonably practicable; assess unavoidable handling; use suitable handling aids, team methods or supports under workplace control
Ejection or tool failure	Incorrect tooling, damaged tool, overloaded machine or unstable workpiece	Confirm tool condition, compatibility and rated capacity from approved information; do not exceed machine or tooling limits
Noise	Hammering, power hammer, guillotine, press shop activity	Use workplace noise assessment and controls; hearing protection only as part of the required control strategy
Hazardous substances	Coatings, degreasers, lubricants, metalworking fluids, fumes from adjacent work	Check COSHH assessment, substitution, ventilation or extraction, safe handling and required PPE
Slips and trips	Offcuts, long stock, hoses, misplaced tools	Allocate stock and scrap locations, maintain clear walkways and keep work area orderly
Burns and hot material	Work near forge processes or recently hot-formed stock	Positive hot-metal identification, segregation, suitable tools and supervision; never assume dark metal is cold
Ergonomic strain	Repeated lifting, awkward reach, holding long work	Plan working height, supports, handling aids, job rotation or process change as required

Manual Handling

The Manual Handling Operations Regulations apply in England. HSE describes a three-part hierarchy: avoid hazardous manual handling where possible; suitably and sufficiently assess unavoidable hazardous manual handling; and reduce the risk of injury so far as is reasonably practicable.^[5] For sheet and long sections, this means planning the move before lifting, using suitable handling equipment where provided, controlling sharp edges and considering the workpiece's size, centre of gravity and travel path.

Noise

The Control of Noise at Work Regulations 2005 apply in Great Britain and therefore in England. HSE gives a lower exposure action value of 80 dB(A), an upper exposure action value of 85 dB(A), and an exposure limit value of 87 dB(A) after taking hearing protection into account.^[6] These figures are not a reason to estimate noise by ear. Use the employer's noise assessment and controls.

PPE

PPE must be selected from the risk assessment and task requirements. Depending on the controlled task, the workplace may specify eye or face protection, hearing protection, protective footwear, protective clothing, gloves or respiratory protection. Never assume that gloves are safe around every rotating or moving machine: follow the machine-specific assessment and instructions. PPE does not make an unsafe machine setup acceptable.

United Kingdom — England: Work-Equipment Duties

For this course, machine-safety duties are referenced to the Health and Safety Executive as the relevant occupational-safety authority for England.

HSE explains that the Provision and Use of Work Equipment Regulations 1998, normally called PUWER, require work equipment to be suitable for its intended use, maintained and inspected as appropriate, used only by people with adequate information, instruction and training, and accompanied by suitable health-and-safety measures such as guarding, emergency stops and means of isolation where needed.^[7]

HSE also states that power presses working cold metal require thorough examination before first use and periodically afterwards, together with frequent inspection and testing of guards and protection devices by a competent person and retained records.^[8] HSE publishes a dedicated Approved Code of Practice and guidance for safe use of power presses.^[9]

What this means for you as a learner: you do not defeat guards, interlocks, two-hand controls, light protective systems or other safeguards; you do not alter machine settings outside your authorisation; you report defects; and you use only the operating mode, tooling and procedure you have been trained and authorised to use.

United Kingdom Standards Check

British Standards can support machinery design, risk assessment, supply, inspection and workplace technical decisions, but a standard is not a replacement for legislation, the manufacturer's instructions or the actual safe system of work.

BSI lists BS EN ISO 12100:2010, Safety of machinery — General principles for design — Risk assessment and risk reduction as current and under review as of the course review date.^[10]

BSI lists BS EN 12622:2009+A1:2013, Safety of machine tools — Hydraulic press brakes as current. Its scope addresses technical safety requirements and protective measures for the design, manufacture and supply of hydraulic press brakes for cold working metal; it is principally a machinery-safety standard, not an operator's setup manual.^[11]

Standards can be revised or replaced. The workplace or competent person must confirm the edition and applicability required for the actual machine and task.

England-Specific Vocational Training Context

Country part: England. Skills England lists the Blacksmith apprenticeship occupational standard ST0378, version 1.1 as approved for delivery, Level 3, with a typical duration of 48 months excluding the assessment period and an earliest start date for version 1.1 of 10 December 2025.^[12]

The standard includes technical interpretation of specifications and drawings, calculation of bending allowances, creation of templates and jigs, selection of appropriate processes and materials, planning and time management, hot forging by hand and machine, bench work, fixed fabrication equipment, quality focus and a positive safety culture.^[13]

No automatic equivalence claim: This England-specific apprenticeship information must not be treated as automatic equivalence with a qualification, apprenticeship, licence, certification or job title in Scotland, Wales, Northern Ireland or another country. Where cross-country recognition matters, obtain advice from the competent authorities and the relevant employer or awarding organisation.

Preparing a Machine-Forming Job

A learner's preparation may include documentation, visual checks and supervised setup activities only to the extent allowed by the training plan. The following are planning principles, not generic operating instructions.

Preparation question	Good practice
Is the machine authorised for the task?	Check the workplace equipment list, machine instructions, process plan and your own authorisation.
Is capacity sufficient?	Verify material, thickness or section, bend length, required forming method and tooling against approved machine and tooling data. Do not guess.
Is the tooling correct and serviceable?	Identify the specified punch, die, roll or former; check identification and visible condition according to the workplace procedure.
Are safeguards available and functional?	Complete the machine-specific pre-use checks required by the workplace. A failed safeguard means stop, isolate or secure the equipment as instructed, label or report it, and do not use it.
Can the workpiece be handled safely?	Plan supports, lifting aids, helpers, travel path and exclusion area before the cycle begins.
Is the datum repeatable?	Confirm stop, backgauge, jig or marked datum and verify it against the drawing.
Is there a first-off plan?	Define measurements and acceptance criteria before producing repeated parts.
Is communication clear?	Agree who controls the operation and how helpers communicate. Nobody should enter a danger zone to correct alignment during a cycle.

Preparing a Manual-Forming Job

For a manual-forming task, inspect and prepare the work area before applying force. Confirm the workpiece can be held securely, the vice, former, stake, bending fork or jig is sound and suitable, and the hammer or mallet is appropriate to the required surface. Plan where hands, helpers and adjacent learners will be positioned.

For decorative repetitions such as scrolls, leaves, brackets or rail components, a durable template or jig can improve consistency. Mark the reference orientation and do not modify a controlled template without approval. If a piece needs heat, that becomes a hot-work or forging operation and must follow the separate supervised forge procedure.

Common Errors and How to Prevent Them

Common error	Likely effect	Prevention during planning
Using unidentified stock	Unpredictable springback, cracking, incorrect strength or wrong finish	Verify specification and condition before work starts
Measuring from the wrong face	Incorrect flange dimension	Mark reference face and datum on drawing and job plan
Ignoring bend sequence	Tooling collision, trapped part, inaccessible datum or unsafe handling	Sketch intermediate shapes and review access before forming
Treating bend allowance as universal	Flat blank too long or too short	Use verified job, material and tooling data
Assuming springback is identical for all materials	Finished angle outside tolerance	Use approved data and first-off inspection
Failing to plan workpiece support	Sudden lifting, loss of control, strain or surface damage	Plan supports and handling aids before the cycle
Relying on PPE instead of safeguards	Exposure to preventable machine hazards	Apply higher-order controls and machine protective measures first
Repeating before first-off acceptance	Batch of defective parts	Inspect and release the first-off before repetition
Marking a finished face with an unsuitable tool	Visible cosmetic damage	Use an approved layout method and protect finish
Mixing scrap grades	Reduced recycling value and traceability problems	Segregate offcuts and recyclable material by workplace system

Quality Criteria

Quality should be defined before the first piece is formed.

Criterion	What to inspect	Suitable evidence
Dimensional accuracy	Flange lengths, overall dimensions, hole-to-bend relationships	Rule, callipers, height gauge, jig or other specified device
Angle	Included or external angle as specified	Angle gauge, protractor, dedicated gauge or approved inspection fixture
Radius	Inside or outside radius as specified	Radius gauge, template or controlled profile check
Straightness	Straight bend line or section edge	Straightedge, surface plate method or jig where appropriate
Squareness	Relationship between faces or features	Engineer's square or inspection fixture
Twist	Unwanted rotation along a section or formed part	Surface, fixture, datum comparison or measured method
Surface condition	Galling, tool marks, dents, scratches, scale or coating damage	Visual inspection under suitable lighting and agreed sample
Edge condition	Burrs, sharp edges and damage	Visual and tactile inspection only after the part is safe to handle
Repeatability	Variation across repeated components	Recorded first-off and in-process measurements
Artistic consistency	Rhythm, curvature, symmetry or intentional variation	Template, master sample, drawing and agreed visual criteria

When a tolerance is stated, inspection equipment must be capable of supporting that decision. Do not use a rough tool to claim precision beyond its capability.

Sustainability and Resource Efficiency

Good planning reduces environmental impact because the most sustainable part is often the one you make correctly the first time. Use accurate development calculations and nesting to minimise offcuts. Reuse suitable remnants where traceability and job requirements allow. Keep ferrous and non-ferrous scrap streams separated according to the workplace recycling system. Avoid contaminating recyclable metal with oils, coatings or mixed waste where segregation is required.

Select the lowest-resource process that still achieves the required result safely and to quality. For a one-off decorative adjustment, a manual jig may be more efficient than a complex machine setup; for repeated accurate parts, a controlled machine process may reduce variation and scrap. Sustainability never justifies bypassing guards, overloading a machine, using unidentified stock or skipping required extraction.

Record recurring defects and rework. A pattern of cracked bends, wrong blanks or scratched surfaces is also a resource-loss signal and should trigger process improvement.

Inclusive Workshop Learning

A safe vocational workshop should allow different learners to demonstrate competence without unnecessary barriers. Instructions should be available in clear English and, where appropriate, supported by diagrams, demonstrations, captions, enlarged drawings or assistive technology. Learners should be able to request clarification without being pressured to enter a hazardous task.

Where a disability, temporary injury, pregnancy, sensory difference or other individual need affects the task, the training provider or employer should carry out the appropriate individual assessment and make reasonable adjustments where required. Adjustments must preserve the effectiveness of risk controls. Never remove a safeguard to make access easier.

Team communication should use agreed, unambiguous words and signals. When several people support a large sheet or section, one authorised method of coordination should be used so that nobody acts on a conflicting command.

Workshop waste audit: Under instructor supervision, examine one completed job's offcuts and rework records and propose two practical ways to reduce material loss without weakening safety controls.

Advanced

Bend sequence review: Given a multi-bend component drawing, compare two possible bend sequences and justify which better preserves datum access, workpiece handling and inspection.
Risk control comparison: Select one machine-forming hazard and compare elimination, engineering, administrative and PPE controls, explaining why the hierarchy matters in the selected England context.
First-off inspection plan: Develop an inspection plan for an artistic or architectural component that combines dimensional tolerances with agreed visual criteria and traceable records.
Expert review video: In a supervised training setting, create a short captioned video that explains the planning stage of a forming job without demonstrating unsupervised hazardous operation, and have a qualified instructor or experienced craftsperson review its accuracy.

Learning Assessment

Applied job planning: From a drawing and material specification supplied by your instructor, produce a route card that links each forming operation to its datum, required resource, risk control and quality check.
Process selection reasoning: Compare manual forming and machine forming for the same decorative component and defend one choice using quality, quantity, material behaviour, access, sustainability and safety.
Risk-transfer scenario: Explain why a setup that was safe and successful on one press brake cannot automatically be transferred to another machine, material or workplace.
Fault diagnosis: A first-off part has the correct bend angle but the flange length is out of tolerance; identify plausible planning causes and describe what evidence you would check before any adjustment.
Safe handling design: Plan how a long or awkward section would move through a forming process while preventing uncontrolled movement and hazardous manual handling.
Sustainability transfer: Analyse a repeated scrap problem and show how improved material verification, development calculation, sequencing or inspection could reduce waste.
Professional judgement: Identify a point at which you would stop a job and seek authorised advice, then justify the decision using the official-rule precedence stated in this course.

Evidence of Learning

Important evidence may include:

Knowledge evidence: Correct use of terms such as datum, bend allowance, bend deduction, springback, first-off, tolerance, former, jig, backgauge and section.
Technical interpretation: Accurate extraction of material, dimensions, radii, angles, tolerances, quantity and finish from current job information.
Planning skill: A logical operation sequence that preserves access, control of the workpiece and measurable datums.
Risk-control reasoning: Identification of hazards and selection of controls using the hierarchy rather than relying only on PPE.
Resource selection: Justified choice of authorised tools, measuring equipment, forming method and work supports.
Quality evidence: A first-off inspection plan and records showing how dimensions, angle, radius, twist and surface condition are accepted.
Sustainability evidence: Practical actions that reduce scrap, rework, unnecessary consumables and mixed recycling.
Transfer achievement: Ability to recognise when a change of material, drawing revision, machine, tooling or workplace invalidates previous assumptions and requires re-verification.
