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 steels
Kinematics: machine tool design;
generation and forming of shapes; six degrees of freedom
