Brake Press Operator
Job Description:1) Sets up and operates power brake to bend, notch, punch, form rolls, arc, or straighten metal plates or sheet metal and structural shapes to
blueprint or sketch specifications: Selects, positions, and aligns dies in machine ram and bed, using shims, rule, square, or templates.
2) Turns setscrews or bolts to fasten clamp bar that holds dies in position.
3) Turns adjustment screws to set specified pressure of ram and clearance between dies to thickness of metal, as indicated by calibrated scale or feelers.
4) Lays out or details layout on work stock from blueprints or templates.
5) Positions workpiece manually or with crane, to align layout marks to dies.
6) Starts machine to lower ram or depresses pedal to activate ram that bends or cuts metal.
7) Sets stops on machine bed and repositions stock to run successive pieces, or to perform multiple operations.
8) Verifies dimensions of workpiece, using template or scale.
9) May preheat metal in furnace or by using oxyacetylene torch.
10) May grind laps or burrs from edges of workpiece, using portable grinder.
11) May devise and build temporary dies.
12) May operate apron brake which bends metal by forcing metal between movable apron and horizontal bending bar.
13) May be designated according to type material processed as Brake Operator, Sheet Metal I; or according to special operations required to process thick metal as Brake Operator, Heavy Duty.

CNC Operator
A CNC (computer numerical control) operator is someone who operates a CNC machine. The CNC machine can perform functions, such as precision drilling and tapping, cutting and shaping steel and aluminum, or milling flat stock into intricate designs. Often called a CNC lathe, the operator programs the machine to perform the task needed and monitors the work, making all necessary adjustments as needed.
In most cases, an operator learns the trade through an apprenticeship program and on-the-job training of a vocational school. He or she must typically understand blueprints and know how to read and interpret them. Computer knowledge is also a requirement, since the CNC machine is computer controlled. By entering a set of numbers in a particular sequence, the CNC operator can program the machine to do any number of functions.
The CNC machine is capable of running large production orders with little to no variance in production pieces. The operator monitors the work being completed and takes many critical measurements. If the machine is producing work that is not satisfactory, small adjustments can be made by the operator using a key pad on the control panel of the machine.
Often, a single operator is assigned to several CNC machines. This is possible due in part to the CNC's ability to provide such close tolerances over a large amount of work. The operator goes from machine to machine, checking the finished product of each. The operator takes critical measurements of each machine's work and implements any needed adjustments.
