CNC Programming

Computer numerical control (programmers) develop programs to be used to operate manufacturing tools and equipment and CNC machinery is used by operators to cut and shape metal and plastic for various types of manufacturing. It is required for a CNC operator to have mechanical skill to read blueprints. Increasingly, many employers also require operators to have basic computer programming skills and experience with computer-aided design and manufacturing programs.
