CNC Programmers
Overview
CNC Programmers write computer code that tells automated machines exactly how to cut, shape, and create parts from metal, plastic, and other materials. You'll analyze blueprints and technical drawings, then create step-by-step instructions that guide machines through precise cutting operations. Using specialized software like CAD programs and simulation tools, you'll test your code virtually before running it on actual machines. This role combines programming skills with hands-on manufacturing knowledge, and you'll often collaborate with engineers and machinists in modern manufacturing facilities.

Key Responsibilities
- Order tooling for jobs.
- Perform preventative maintenance or minor repairs on machines.
- Align and secure pattern film on reference tables of optical programmers, and observe enlarger scope views of printed circuit boards.
- Determine reference points, machine cutting paths, or hole locations, and compute angular and linear dimensions, radii, and curvatures.
- Write programs in the language of a machine's controller and store programs on media, such as punch tapes, magnetic tapes, or disks.
- 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.
- Write instruction sheets and cutter lists for a machine's controller to guide setup and encode numerical control tapes.
- Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.
- Determine the sequence of machine operations, and select the proper cutting tools needed to machine workpieces into the desired shapes.
- Sort shop orders into groups to maximize materials utilization and minimize machine setup time.
- Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data to calculate dimensions, tool selection, machine speeds, and feed rates.
- Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications.
- Revise programs or tapes to eliminate errors, and retest programs to check that problems have been solved.
- Compare encoded tapes or computer printouts with original part specifications and blueprints to verify accuracy of instructions.
- Enter coordinates of hole locations into program memories by depressing pedals or buttons of programmers.
