Manual and machine forming of sheet and sections — Safe practice

Introduction

Manual and machine forming of sheet and sections — Safe practice is a vocational learning module for learners in Blacksmithing, artistic metalwork, fabrication and related craft workshops. It focuses on how you prepare, control, monitor and stop forming work safely while maintaining craft quality.

Jurisdiction: England, United Kingdom. Workplace-safety references in this course use current guidance from the UK Health and Safety Executive (HSE) that applies in England as part of Great Britain. The vocational-training reference is for England only and uses Skills England. British Standards Institution (BSI) listings are used to identify relevant current British machinery-safety standards. This course does not claim automatic equivalence with Scotland, Wales, Northern Ireland or any other country.

Authority and supervision notice: Official legislation, HSE guidance, your employer's risk assessments and safe systems of work, your training provider's instructions, the machine manufacturer's instructions and competent supervision take precedence over this learning material. You must not use, set, adjust, clean, clear, maintain or bypass safeguards on hazardous machinery unless you are trained, authorised and following the approved procedure. Never carry out hazardous forming work unsupervised merely because you have completed this aiMOOC.

Learning Outcomes

After completing this module, you should be able to:

Hazard recognition: Identify crushing, shearing, drawing-in, trapping, impact, sharp-edge, handling, noise, hot-work and substance hazards associated with forming sheet and sections.
Risk control: Explain why elimination, engineering safeguards and safe systems of work normally take priority over personal protective equipment.
Machine safety: Recognise the function of guards, protective devices, emergency controls, isolation arrangements and controlled work zones without treating any one measure as sufficient by itself.
Safe setup: Carry out a supervised pre-use check and prepare material, supports, tools and the work area according to the approved procedure.
Forming quality: Relate safe control of the workpiece to bend angle, bend radius, symmetry, surface quality, repeatability and dimensional accuracy.
Stop-work judgement: Stop and seek competent assistance when a guard, control, setup, material condition or machine behaviour is abnormal.
Sustainability: Reduce scrap, rework, wasted energy and consumables without weakening safety controls.
Professional practice: Record checks, communicate hazards and work within the limits of your training and authorisation.

What Forming Means in the Workshop

Forming changes the shape of metal mainly by controlled plastic deformation rather than by removing material. In blacksmithing and artistic metalwork, forming can be performed cold or hot, by hand or by machine. The same design may combine several processes.

Sheet is flat metal stock supplied in gauges or thicknesses suitable for operations such as folding, flanging, curving, sinking or wheeling. Sections are shaped stock such as flat bar, angle, channel, round bar, square bar, tube, box section and other structural or decorative profiles.

Common UK workshop terms include sheet-metal folder, box-and-pan folder, press brake, bending rolls, section rolls, English wheel, fly press, power hammer, stakes, formers, jigs and templates. Individual workshops and manufacturers may use different names, so you should always identify the exact machine and its controls before work begins.

The diagram above illustrates the relationship between a folded sheet component and its position in a folding machine. In real work, the bend line, bend radius, material thickness, grain or rolling direction where relevant, springback and the machine's tooling all affect the finished geometry. Safety controls must remain effective throughout the setup and forming sequence.

Core Safety Concepts

Hazard, Risk and Control

A hazard is something with the potential to cause harm. Risk considers the likelihood and possible severity of that harm in the circumstances of the work. A control measure reduces the likelihood, the severity, or both.

For forming operations, the workpiece can itself become part of the hazard. Long material can sweep sideways; springy material can move unexpectedly when force is released; thin sheet can have razor-like edges; hot metal can look similar to cold metal; and a heavy panel can become unstable when its centre of gravity shifts.

Hierarchy of Control

Use controls in a planned order rather than relying on PPE alone.

Control level	Forming-work example
Eliminate	Redesign the task so a dangerous manual intervention or unnecessary operation is not required.
Substitute or reduce exposure	Use a safer process, suitable pre-cut blank, smaller manageable component or approved handling aid where the risk assessment supports it.
Engineering controls	Fixed or interlocked guards, protective devices, enclosed drives, correctly designed tools, supports and effective emergency controls.
Administrative controls	Training, authorisation, supervision, safe systems of work, inspection, exclusion zones, communication and maintenance procedures.
Personal protective equipment	Suitable eye, face, hearing, foot, body or hand protection selected for the task and residual risk, without introducing entanglement or other hazards.

PPE is important, but it is not a substitute for effective machine safeguarding, competent setup or isolation.

Danger Zones Around Forming Equipment

Danger zone	What can happen	Safer principle
Point of operation	Crushing, shearing or trapping between tooling and the workpiece	Prevent access by suitable guarding or protective devices and use the approved operating method
In-running nip	Material, clothing or body parts can be drawn between rotating surfaces	Keep outside the danger zone and use guarding, distance, supports and the approved feed method
Sweep zone	Long stock can swing, rise, fall or travel as it is formed	Establish a clear controlled area and support the stock
Rear or side access	A person can enter a hazardous area not visible to the operator	Control access and communication; use machine-specific safeguards
Stored energy zone	Gravity, springs, hydraulics, pneumatics or suspended parts can move after normal stopping	Apply the approved isolation procedure and dissipate or restrain stored energy before intervention
Ejected-material zone	Scale, fragments, tools or poorly secured work can be projected	Secure tooling and work appropriately, maintain distance and use suitable guarding and PPE

Tools, Machines and Materials

Manual Forming Tools

Typical manual tools include hammers, mallets, stakes, anvils, swages, fullers, bending forks, scrolling tools, formers, bending jigs, vice-mounted tools and sheet-metal seaming or folding tools. Check that hammer heads and handles are sound, stakes are secure, workholding is stable and striking faces are appropriate to the task. A loose stake or unstable workpiece can turn a controlled blow into an impact or projection hazard.

When hand forming, control matters more than force. Stand securely, keep other people out of the swing path, choose a hammer mass you can control and avoid striking hardened surfaces together unless the tools are designed for that use.

Sheet-Metal Folders and Press Brakes

A sheet-metal folder clamps the sheet and rotates a folding beam to make a bend. A press brake forms sheet or plate between upper and lower tooling. Press brakes can generate very large forces and create severe crushing and shearing hazards at the point of operation. Modern safeguarding arrangements vary by machine, tooling, mode and task. Never assume that a guard or light-based protective device makes every setup safe.

Supplementary video — machine familiarisation only, not operating authorisation:

Before any press-brake task, the competent person must ensure that the machine, tooling, safeguarding, control mode, material support and planned sequence are suitable. Learners must not change safety settings, bypass protective devices or improvise access to the tooling area.

Bending Rolls and Section Rolls

Bending rolls curve sheet, plate or sections by passing the work through rollers. The most obvious hazards are in-running nips, but the moving workpiece can create an equally important sweep or lift hazard. The exit side may be hazardous even when the operator is standing at the entry side.

Long sections need planned support and a clear zone. Do not reach between rollers, attempt to hand-correct material close to rotating parts or clear a jam while the machine is capable of movement.

English Wheel

The English wheel stretches and smooths sheet between an upper wheel and a lower anvil wheel. It is widely used for compound curves in coachbuilding, sculpture and artistic metalwork. Although slower than many powered machines, it still presents pinch and trapping points and can require strenuous handling of large panels.

Supplementary video — observe technique and workpiece control:

For large panels, plan how the sheet will move before applying pressure. Keep your hands away from the wheel contact area, avoid sharp burrs and arrange help or supports when the panel cannot be controlled comfortably by one person.

Power Hammers and Forging Presses

Blacksmithing workshops may use power hammers and forging presses to form hot stock. Hazards include crushing, impact, scale, heat, noise, tool failure and unexpected workpiece movement. These machines require task-specific instruction, competent supervision, secure tooling and disciplined communication.

Supplementary video — safety discussion, not a substitute for supervised instruction:

Never place any part of your body in a powered hammer or press danger zone. Do not hold tools, workpieces or helpers in positions that conflict with the workshop's approved system of work.

Materials and Formability

Common materials include low-carbon steel, stainless steel, aluminium alloys, copper, brass and, for forging, suitable forgeable steels. Their behaviour differs.

Springback is elastic recovery after the forming force is removed. Work hardening is an increase in hardness and reduction in ductility caused by plastic deformation in some metals. Coatings, scale, lubricants, residues and metalworking fluids can introduce additional hazards that must be considered under the workplace COSHH assessment where applicable.

Never heat an unknown, coated or contaminated material simply to make it easier to form. Heating can create toxic fumes, fire hazards or unexpected metallurgical effects. Identify the material and follow the approved process.

Safe Practice in England

Workplace Safety Duties and HSE Guidance

For workplaces in England, the Health and Safety Executive provides authoritative guidance on the Provision and Use of Work Equipment Regulations 1998, commonly called PUWER. HSE guidance emphasises that work equipment must be suitable, maintained in a safe condition and, where necessary, inspected. People who use, supervise or manage the use of work equipment must receive adequate information, instruction and training.

Machine safety is not limited to normal production. Cleaning, adjustment, blockage clearing and maintenance can expose people to hazards that guards control during normal use. HSE guidance therefore stresses safe stopping and isolation, including controlling stored energy where necessary, before intervention.

Certain power presses have additional PUWER requirements. Do not apply power-press inspection rules to a machine merely because it is called a press: the competent person must identify the equipment type and the exact legal requirements that apply. HSE's power-press Approved Code of Practice and guidance should be consulted for relevant machines.

HSE noise guidance states exposure action values of 80 dB(A) and 85 dB(A), with an exposure limit value of 87 dB(A) after accounting for hearing protection. These figures do not mean that hearing protection alone is an adequate noise-control strategy.

Vocational Training Reference — England Only

Skills England lists the Blacksmith occupational standard ST0378, version 1.1 as approved for delivery at Level 3. It describes blacksmithing as designing, shaping and joining metal by hot forging and other metalworking processes for bespoke, small-batch and heritage work, and it includes safe use of hand tools, fixed forge equipment, fabrication equipment and risk-control knowledge.

This aiMOOC can support learning associated with those knowledge and skill areas, but completion of this course does not award the apprenticeship, a regulated qualification, a legal certificate of competence or workplace authorisation. Employers, training providers and assessment organisations determine competence and authorisation within the applicable framework.

No automatic equivalence is claimed with apprenticeships, licences, certificates, job titles or training pathways in Scotland, Wales, Northern Ireland or any other country.

Standards Reference — United Kingdom

BSI currently lists BS EN ISO 12100:2010 — Safety of machinery. General principles for design. Risk assessment and risk reduction as current and under review. BSI also lists BS EN ISO 13857:2019 — Safety of machinery. Safety distances to prevent hazard zones being reached by upper and lower limbs as the current edition replacing the withdrawn 2008 edition.

Standards support good practice but do not replace legislation, a machine-specific risk assessment or the manufacturer's instructions. A draft or proposed revision does not automatically replace an adopted standard. Your organisation should confirm the standards and editions relevant to its machinery and duties.

Risk Controls by Operation

Hand Hammering, Raising and Forming on Stakes

Before work, inspect hammers, mallets, stakes, anvils, formers and workholding. Secure detachable stakes and make sure the floor and striking area are clear. Choose a stance that keeps you balanced and keeps others out of the hammer swing. Remove or control burrs and sharp projections. For hot work, identify hot stock clearly and use suitable tongs or handling tools.

Eye protection is commonly required because scale or fragments may be released. Hearing protection may also be required by the workshop noise assessment. Gloves require task-specific judgement: they can help with sharp or hot material, but loose or inappropriate gloves can increase entanglement risk near moving machinery.

Sheet-Metal Folders and Press Brakes

Use only tooling that the competent person has approved for the material, thickness, bend and machine capacity. Keep the point of operation protected by the machine's designed safeguards. Support large sheet so it cannot drop, tilt or pull the operator toward the tooling. Check that the work will not strike another person, wall, bench, control or stored material during the bend.

If a workpiece is misaligned, a guard is displaced, a protective device is faulted or the sheet becomes trapped, stop. Do not reach into the danger zone or improvise a bypass. Follow the approved stop and isolation process and seek competent assistance.

Bending Rolls and Section Rolls

Before rolling, identify the entry nip, exit movement and full sweep of the workpiece. Establish an exclusion area when long or curved stock can travel beyond the machine footprint. Use manufacturer-approved supports or handling aids. Keep loose clothing, hair, jewellery and unsuitable gloves away from rotating parts.

Do not try to flatten a kink, pull a section back into line or remove debris while rollers can move. Stop and use the machine-specific intervention procedure.

Hot Forming at the Forge

Control fuel, ventilation, hot-work hazards, scale, radiant heat and the travel path between forge, anvil and forming machine. Use the workshop's system for marking or segregating hot metal. A piece that has cooled below visible red heat may still cause a serious burn.

Power hammer and press work needs coordinated control of tooling, stock and communication. If more than one person is involved, the workshop must have a clear method for who controls the cycle and how anyone can signal a stop.

Handling Sheet and Long Sections

Sharp-edged sheet and strip can cause severe cuts. Large sheets can act like sails, obscure vision and shift suddenly. Long sections can be awkward because their centre of gravity is far from the hands.

Assess the load, route, grip, edges, weight, dimensions and team requirements before moving it. Use suitable racks, trolleys, lifting or handling aids where provided. Store sheet and sections so they cannot slide, roll, topple or create projecting-end hazards.

Pre-Use Safety Routine

Use this routine only within your workplace's approved procedure and under the level of supervision required for you.

Job brief: Confirm the drawing, forming sequence, material, dimensions, acceptable tolerances and who is supervising or authorising the work.
Machine identification: Confirm the exact machine, its rated capacity, controls, operating mode and manufacturer's instructions.
Material identification: Check material grade where required, thickness or section size, condition, coatings, burrs and any heat-related restrictions.
Tooling check: Confirm that dies, formers, rollers, stakes, jigs and supports are correct, secure, compatible and within their permitted condition.
Safeguard check: Verify that guards, protective devices, interlocks and emergency controls are present and pass the checks required by the local procedure.
Area check: Remove slip and trip hazards and establish clear access, lighting and an adequate workpiece sweep zone.
Handling plan: Provide supports, trolleys or team assistance for sheet or sections that cannot be controlled safely by one person.
PPE check: Wear task-specific PPE required by the risk assessment and make sure it does not introduce an entanglement or visibility problem.
Communication check: Agree who operates the machine, who supports the work and what stop signal will be used when more than one person is involved.
Trial plan: Where authorised, plan a representative test coupon or low-risk trial according to the approved procedure before committing valuable material.
Stop criteria: Know in advance which abnormal sounds, movement, dimensions, guard faults or material behaviour require you to stop and seek help.

Step-by-Step Demonstration

Supervised Cold Bend on a Manual Sheet-Metal Folder

This demonstration is intentionally limited to a basic cold bend on an appropriate manual sheet-metal folder. It does not authorise you to use a powered press brake, powered rolls, power hammer or forging press. A competent instructor must select the machine, material and settings and must supervise the activity according to the local risk assessment.

Read the job information: Identify the material, finished dimensions, bend line, required bend direction, nominal angle and quality criteria on the drawing or exercise sheet.
Confirm authorisation: Ask the instructor to confirm that you may use the selected manual folder and that the task is within the machine's capacity.
Inspect the blank: Check size, surface, edges, burrs, coatings and damage; deburr or handle the part only by the approved method.
Inspect the folder: With the machine in the condition specified by the instructor, check that the clamping and folding components, handles, stops and supports show no obvious defect.
Clear the area: Make sure the floor is clear and that the sheet can move through its full path without striking another person or object.
Mark and reference: Use the approved datum and bend-line marking method; avoid marks that damage a finished surface unless permitted.
Present the sheet: Support the sheet and align the bend line to the machine reference as demonstrated, keeping hands outside pinch and clamp zones.
Clamp by the approved method: Operate the manual clamp exactly as instructed and confirm that the blank remains square and stable.
Make the bend: Move the folding beam smoothly using the designed handle; keep your body clear of the handle and workpiece travel path and stop if the blank shifts unexpectedly.
Release and remove: Return the mechanism to its safe rest position, release the clamp by the approved method and remove the part while controlling sharp edges.
Inspect quality: Away from danger zones, check bend angle, flange size, straightness, surface condition and consistency against the drawing or sample.
Record and improve: Note any springback or dimensional variation, discuss the cause with the instructor and change the next trial only with approval.

Quality Check After the Demonstration

Criterion	What you inspect	Evidence
Bend position	Bend line is located from the correct datum	Rule, square, gauge, drawing or approved inspection method
Bend angle	Finished angle meets the specified tolerance	Angle gauge, protractor, template or approved gauge
Flange size	Finished leg or flange dimension is within tolerance	Direct measurement from the stated datum
Straightness	Bend is not visibly bowed or locally distorted beyond acceptance criteria	Straightedge, surface plate method or approved visual standard
Surface	No unacceptable tool marks, cracks, deep scratches or coating damage	Visual and tactile inspection where safe
Repeatability	Similar parts or test coupons show consistent results	Recorded measurements and comparison

Common Errors and Safer Corrections

Common error	Why it matters	Safer response
Reaching toward a moving tool to correct alignment	Creates direct exposure to crush or shear zones	Stop; return the machine to the approved safe condition and realign only by the authorised method
Treating an emergency stop as a normal isolation device	Stored or restorable energy may remain	Use the documented isolation procedure for intervention
Holding long stock without planning its movement	The material can sweep, lift, drop or lever the operator	Establish the sweep zone and suitable supports before starting
Increasing force because a bend is not progressing	May indicate wrong capacity, tooling, material or setup	Stop and have a competent person verify the setup
Ignoring burrs because gloves are worn	Burrs can cut through gloves and create handling problems	Remove or control sharp edges by the approved method and choose suitable handling controls
Assuming every press brake has the same safeguarding	Machines, modes and protective systems differ	Learn the exact machine and follow its risk assessment and manufacturer's instructions
Measuring close to moving machinery	Brings hands and attention into a danger zone	Stop and measure at the designated safe inspection point
Making an unauthorised guard or control adjustment	Can defeat a safety function	Stop and refer the issue to an authorised competent person
Correcting a defect by repeated unplanned passes	Adds exposure, work hardening, distortion and scrap	Diagnose the cause and agree the next controlled step before reworking

Quality Criteria for Formed Work

Safe practice and quality are connected. Stable support, repeatable datums, controlled force and planned sequencing reduce both injury risk and defects.

Quality criterion	Typical defect	Possible process cause to investigate
Dimensional accuracy	Flange too long or short	Wrong datum, bend location or allowance
Angular accuracy	Bend too open or too closed	Springback not accounted for or inconsistent forming
Profile accuracy	Radius varies along a curved section	Uneven passes, poor support or unsuitable setup
Symmetry	Paired scrolls or curves do not match	Inconsistent jig reference or sequence
Surface quality	Dents, galling or wheel tracks	Damaged tooling, contamination or excessive local pressure
Section integrity	Tube or box section twists or collapses	Unsuitable radius, tooling or rolling strategy
Edge quality	Cracking begins at an edge	Burr, poor edge condition, unsuitable bend direction or insufficient ductility
Repeatability	Parts vary from one another	Uncontrolled setup, inconsistent reference or undocumented adjustment

A competent craftsperson does not hide a process defect that may affect structural or functional performance. Record and escalate defects according to the workshop quality procedure.

Sustainability and Resource Efficiency

Sustainable metalworking begins with preventing waste. A safe, well-planned process is often also the lower-impact process.

Material efficiency: Plan blanks, bend allowances, nesting and forming sequence to reduce offcuts and rejected parts.
Test pieces: Use representative test coupons when justified, but keep trials purposeful and record the result so the same test is not repeated unnecessarily.
Tool life: Maintain tooling and keep contact surfaces clean so poor condition does not create scrap or excessive marking.
Energy use: Avoid unnecessary heating, idling or repeated powered passes while still following warm-up, ventilation and safety requirements.
Reuse and recycling: Segregate clean metal offcuts by workshop policy so suitable material can be reused or recycled.
Coatings and fluids: Use only approved quantities and dispose of contaminated wipes, fluids, coatings and residues through the correct waste stream.
Repair before remaking: Rework only when technically acceptable and safe; do not save material by accepting a defective or unsafe component.
Design for manufacture: Where design freedom exists, choose forms, radii and section sizes that can be produced reliably with available equipment and minimal waste.

Sustainability never justifies disabling extraction, reducing guarding, skipping inspection or using a machine beyond its capacity.

Inclusive and Accessible Workshop Practice

A safe workshop is designed for varied bodies, experience levels and communication needs. Do not assume that every learner has the same reach, grip strength, hearing, vision, reading speed or previous workshop experience.

Use clear demonstrations, readable drawings, plain-language instructions and agreed hand or verbal signals. Adjust work height and handling methods where practicable. Provide suitable lifting aids, task rotation and support rather than expecting a learner to compensate for a poor setup with extra force. Personal protective equipment must fit the wearer and remain compatible with other PPE.

Learners should be able to report uncertainty, fatigue, pain, an unsafe condition or a near miss without being pressured to continue. A competent supervisor decides whether the task, equipment or support needs to change.

Reflection

Think about a forming task you have observed in a real workshop. Where was the point of operation? Which part of the workpiece moved furthest? What could have happened if the workpiece slipped? Which control prevented access to the main danger zone? Which hazards remained after engineering controls were in place? Finally, identify one moment when an apprentice should stop and ask for competent help rather than trying to solve the problem alone.

Open-Ended Tasks

Easy

Danger-zone sketch: Draw a labelled diagram of a sheet-metal folder or forming machine you are allowed to observe, showing the point of operation, workpiece travel and a safe observer position; have an instructor review it before you enter the work area.
Safe-work vocabulary: Create ten illustrated vocabulary cards using practitioner terms from the glossary and add one safe-practice sentence to each card.
Media observation: Watch one embedded video without copying the operating technique, then identify visible safeguards, workpiece-control methods and questions you would ask the instructor before using similar equipment.
Quality checklist: Make a one-page inspection sheet for a simple cold-formed bracket covering bend position, angle, dimensions, straightness and surface condition.

Standard

Supervised pre-use check: Under direct instructor supervision, complete the approved pre-use checklist for one manual forming station and record any condition that requires escalation rather than operation.
Risk-control comparison: Compare hand forming, a manual folder and powered rolls for one workshop product and explain how the danger zones and risk controls change between the three methods.
Expert interview: Interview a competent blacksmith, fabricator, technician or instructor about one real forming near miss or recurring hazard, then summarise the control improvements without naming individuals.
Material trial plan: Design a supervised test-coupon plan for comparing springback in two approved sheet materials, including measurements, stop criteria, expected waste and how the trial result would reduce rework.

Advanced

Machine-specific risk review: With access authorised by your training provider, compare the manufacturer's instructions, local risk assessment and actual safeguarding for one forming machine; report discrepancies to the competent person and do not alter the machine yourself.
Process redesign: Redesign a forming sequence for a decorative metal component to reduce handling, scrap and exposure to danger zones while preserving the specified geometry and finish.
Training microvideo: Produce a short supervised training video about pre-use inspection, exclusion zones and stop-work decisions; do not demonstrate guard bypassing, maintenance access or unsupervised hazardous operation.
Expert-review dossier: Assemble a review pack containing a process map, hazard register, quality criteria, sustainability notes and citations to current HSE, Skills England and BSI sources, clearly separating legal duties, vocational references and standards.

Learning Assessment

Hazard-to-control reasoning: Given a sketch of a press-brake task with a large sheet, identify at least four hazards and justify controls using the hierarchy of control rather than listing PPE alone.
Stop-work decision: Analyse a scenario in which a section begins to twist and make abnormal contact with rolling equipment; explain when you would stop, what you would secure or isolate under the approved procedure and who must decide the next step.
Method selection: Compare manual forming, a folder and section rolls for a specified artistic-metalwork component and defend the method that best balances safety, quality, material use and available competence.
Defect diagnosis: Inspect a sample or measurement set showing inconsistent bend angles and propose a structured investigation that separates material behaviour, datum error, tooling condition and operator method.
Sustainability transfer: Redesign a small-batch forming job to reduce scrap and unnecessary energy use without weakening safeguarding, supervision or inspection.
Competence boundary: Explain the difference between learning about a machine, being trained to use it, being assessed as competent for a task and being authorised by an employer or workshop to carry it out.

Evidence of Learning

Evidence type	What successful evidence can show
Knowledge	You distinguish hazards, risks, danger zones, safeguards, isolation, springback, work hardening, handling risks and quality criteria using correct workshop terminology.
Practical skill	Under appropriate supervision, you prepare a simple manual forming task, control the workpiece, use a datum and stop when conditions fall outside the approved method.
Product	You produce a formed sample that meets stated dimensional, angular, surface and repeatability criteria without hiding defects.
Documentation	You complete a pre-use record, quality check, risk-control explanation and process reflection clearly enough for an instructor or employer to review.
Reflection	You identify where your own competence ends, when help is required and how feedback changes your next supervised attempt.
Transfer	You apply the same safety reasoning to an unfamiliar forming process by identifying danger zones, energy, workpiece movement, safeguards, inspection needs and stop criteria before proposing action.
