CNC Programmer

JOB SUMMARY

Develop programs to control machining or processing of metal parts by automatic machine tools,

equipment, or systems.

PRINCIPLE ACCOUNTABILITIES include

• Determine the sequence of machine operations and select the proper cutting tools needed to machine work

pieces into the desired shapes.

• Revise programs or tapes to eliminate errors, and retest programs to check that problems have been solved.
• Analyze job orders, drawings, blueprints, specifications and design data to calculate dimensions, tool

selection, machine speeds, and feed rates.

• Determine reference points, machine cutting paths or hole locationsand compute angular and linear

dimensions, radii, and curvatures.

• Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery

will function properly and produce items that meet specifications.

• Compare programs or computer printouts with original part specifications and blueprints to verify

accuracy of instructions.

• Write programs in the language of a machine's controller or on a CAM system and store programs on company network drives.
• Modify existing programs to enhance efficiency.
• Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer

data to other media.

Additional responsibilities and duties may be assigned.
