CNC programming courses include fundamentals such as basic principles of CNC machining, CNC programming structure, types of CNC machines and scope of CNC machining. Students learn to calculate processing measurements such as feed rates, tap drill sizes, diameters, helix angles and tool RPM. Students also learn to read technical drawings, use measuring devices and understand geometric dimensioning and tolerances. Computer simulation software helps students visualize the applications of CNC.

A CNC lathe course covers lathe machining operations such as drilling, grooving, threading and facing. Students learn program space reduction, design programs based on turning tool nose radius compensation and feed commands into the CNC lathe. A CNC mill course features topics such as co-ordinate systems, machine axis, modal and nonmodal commands, functions and tool RPM calculations. It prepares students to interpret blueprints, structure programs and perform basic manufacturing operations.

CNC programming features various functions and commands, including dwell commands, interpolation, canned cycles, helical motion and mirror image. CNC programmers use commands that instruct machines to manufacture precision parts with applications in several industries.
