| Task | AI exposure |
|---|---|
| Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer data to other media. Storing and retrieving program files is routine digital work. | 76% AI can do it |
| Enter coordinates of hole locations into program memories by depressing pedals or buttons of programmers. Hole coordinates can be entered from drawings by software. | 74% AI can do it |
| Write programs in the language of a machine's controller and store programs on media, such as punch tapes, magnetic tapes, or disks. CAM and LLMs generate controller code; storing files is trivial. | 72% AI can do it |
| Compare encoded tapes or computer printouts with original part specifications and blueprints to verify accuracy of instructions. Comparing code or printouts against specs is document checking. | 72% AI can do it |
| Write instruction sheets and cutter lists for a machine's controller to guide setup and encode numerical control tapes. Setup sheets and cutter lists can be generated from program data. | 72% AI can do it |
| Determine reference points, machine cutting paths, or hole locations, and compute angular and linear dimensions, radii, and curvatures. Geometry and hole coordinate calculations are well suited to software. | 66% AI can do it |
| Sort shop orders into groups to maximize materials utilization and minimize machine setup time. Nesting and batching optimization is handled well by scheduling software. | 64% AI can do it |
| Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper. CAD tools generate layouts from specs; designer reviews the output. | 60% AI helps |
| Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data to calculate dimensions, tool selection, machine speeds, and feed rates. AI can calculate dimensions and speeds from drawings; engineer verifies. | 58% AI helps |
| Modify existing programs to enhance efficiency. AI can suggest efficiency edits; machinist must validate changes. | 58% AI helps |

| Revise programs or tapes to eliminate errors, and retest programs to check that problems have been solved. AI can find and fix code errors; retesting needs machine time. | 56% AI helps |
| Order tooling for jobs. Tool lists and purchase orders can be drafted; buyer approves vendors. | 52% AI helps |
| Determine the sequence of machine operations, and select the proper cutting tools needed to machine workpieces into the desired shapes. AI suggests operation sequences and tools; shop judgment still needed. | 50% AI helps |
| Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications. Simulation is automated, but trial runs need a person at the machine. | 40% AI helps |
| Perform preventative maintenance or minor repairs on machines. Hands-on machine maintenance and repair needs physical presence. | 15% Needs a person |
| Align and secure pattern film on reference tables of optical programmers, and observe enlarger scope views of printed circuit boards. Physically aligning film on optical equipment is hands-on work. | 12% Needs a person |

Questions about CNC programmers and AI
Will cnc programmers be replaced by AI?
Partly. About 6 in 10 working hours go to tasks AI can already do, mostly writing machine controller code and calculating hole coordinates and cutting paths. Setup on the machine, trial runs and hands-on maintenance stay with people because they need a person at the equipment.
Which CNC programmer tasks is AI taking over?
Writing controller code, entering hole coordinates and storing program files are the most exposed tasks, with exposure scores of 72 to 76. Mastercam and other CAM software already generate G-code from models, and file storage is routine digital work that software handles well.
Which CNC programmer tasks stay human?
Preventative maintenance, aligning film on optical programmers and observing trial runs stay with people. Maintenance scores 15 for exposure and trial runs score 40, because a person has to stand at the machine to hear chatter, see the cut and measure the finished part.
How can CNC programmers stay valuable?
Run first-article trial cuts on the machine and log results, since test runs need a person at the spindle. Hold a NIMS CNC credential and write setup sheets that shop operators can check against drawings. Learn Fusion 360 or Mastercam post processors so you tune G-code for each controller, and model parts in SolidWorks to check hole geometry before programming starts.
