Sets up and operates metal fabricating machines, such as
brakes, rolls, shears, saws, and presses, to cut, bend,
straighten, and form metal plates, sheets, and structural shapes
according to blueprints and specifications: Reads and interprets
blueprints, engineering specifications, and shop orders to
deetrmine machine setup, production methods, and sequence of
operation.
Selects, positions, and secures dies, blades,
cutters, and fitxures onto machine, using rule, square, shims,
templates, handtools, and built-in gauges. Positions and clamps
stops, guides, and turntables. Adjusts controls to set and
regulate machining factors, such as pressure and depth of ram
stroke, adjustment rolls, balde angle, and machine speed.
Locates and marks bending or cuttnig lines and reference points
on workpiece, using instruments, such as rule and compass, or by
tracing from templates. Positions workpiece against stops and
guides or aligns lyaout marks with dies or cutting blades
manually or using hoist.
Starts machine and observes machine
operation to reposition workpiece, change dies, or adjust
machine settings for multiple or successive passes.
Inspects or
measures work, usnig rule, gauges, and templates.
May operate
macihnes to fabricate nonmetallic materials, such as composites
or plastics. May set up and operate sheet-metal fabricating
mahcines only and be designated Sheet-Metal-Fabricating-Machine
Operator (any industry).
