Task 1 P1 Identify the health and safety legislation, regulations and safe working practices
applicable in a fabrication workshop, with learners being asked to produce a written report. Evidence presented for P1 must be specific to fabrication processes. There is a huge amount of generic material which learners will have access to. Care should be taken to ensure that what you present is referenced properly and not directly copied from the internet or any other source.

P8 identify the appropriate heat treatment processes, secondary, finishing and assembly techniques needed to manufacture four given components.
Given components are
Upright for the front suspension on the Green power racer. Anodise it .
A garden gate, hot galvanised
Use this for the Water pump Grind the main shaft as the finishing technique
Lathe and surface hardening should come into play!
an engine block rough cast to finished surfaces. Milling machine.

Know how a range of non-traditional techniques are used
Electro discharge: machines eg spark erosion, wire erosion; features of the workpiece eg holes, faces (such as flat, square, parallel, angular), forms (such as concave, convex, profile, square/rectangular), other features (such as threads, engraving, cavities, radii/arcs, slots)
Broaching: machines eg horizontal, vertical; features of the workpiece eg keyways, holes (such as flat sided, square, hexagonal, octagonal), splines, serrations, other special forms
Honing and lapping: machines eg honing (such as horizontal, vertical), lapping (such as rotary disc, reciprocating); features of the workpiece eg holes (such as through, blind, tapered), faces (such as flat, parallel, angular)

1 Understand how a range of secondary machining techniques are used
Turning: machine eg centre lathe, turret; features of the workpiece eg flat faces, diameters (such as parallel, stepped, tapered), holes (such as drilled, bored, reamed), profile forms, threads (such as internal, external), eccentric features, parting off, chamfers, knurls or special finishes, grooves, undercuts
Milling: machine eg horizontal, vertical, universal, planer/gantry; up-cut; down-cut; features of the workpiece eg faces (such as flat, square, parallel, angular), steps/shoulders, slots (such as open ended, enclosed/recesses, tee), holes (such as drilled, bored), profile forms (such as vee, concave, convex, gear), serrations, indexed or rotated forms, special forms
Boring: machine eg horizontal, vertical; features of the workpiece eg bored holes (such as through workpiece, to a depth, tapered), holes (such as drilled to depth, drilled through workpiece, reamed, threaded), external diameters, grooves/recesses, chamfers/radii, faces (such as flat, square, parallel, angular, milled), slots, forms (such as indexed, rotated), external tapers
Grinding: machine eg surface (such as horizontal, vertical), cylindrical (such as external, internal), centreless, universal, thread, profile; features of the workpiece eg faces (such as flat, vertical, parallel, square to each other, shoulders and faces), slots, diameters (such as parallel, tapered), bores (such as counterbores, tapered, parallel), profiles forms, thread forms (such as vee, right hand, single start, multi-start, internal, external), angular faces
Presswork: machines eg single action, multiple action; features of the workpiece eg blanking, notching, piercing, joggling, cropping/shearing, bending/forming, coiling/rolling, planishing/flattening, first draw, second draw, compound operations, cupping, embossing, coining
Health and safety: appropriate legislation and regulations eg Health and Safety at Work Act 1974, Fire Precautions Act 1971, manual handling, Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) 1995, Provision and Use of Work Equipment Regulations (PUWER) 1998, Health and Safety (First Aid) Regulations 1981; use of personal protective equipment (PPE)
Materials: eg ferrous, non-ferrous, non-metallic, stainless, special alloys, deep drawing steelsKinematics: machine tool design; generation and forming of shapes; six degrees of freedom
P1 explain how five different secondary machining techniques are used safely on a range of materials
P2 explain kinematics in secondary machining techniques
