Tool and die makers use CAD to develop products and parts. They enter designs into computer programs that produce blueprints for the required tools and dies. Computer numeric control programmers, described in the metal and plastic machine workers profile, convert CAD designs into CAM programs that contain instructions for a sequence of cutting-tool operations. Once these programs are developed, CNC machines follow the set of instructions contained in the program to produce the part. Machinists normally operate CNC machines, but tool and die makers often are trained to both operate CNC machines and write CNC programs and thus may do either task.
