A CAM System produces a GCode program that runs a CNC machine. CNC Equipment comes in many flavors: Horizontal and Vertical Machining Centers (Mills), Two & Fours Axis Lathes, CY Axis Lathes (a mill and lathe in one machine), Routers, two & four axis wire EDM, Screw Machines, Lasers, Plasma Arcs, Punch and Nibble (fabrication equipment) and Water Jets. Then there is the Software to support CAM (getting the program to the machine) DNC - Direct Numerical Control. This software communicates from the computer at the programmer's desktop to the CNC Machine transmitting the program to the Machine that produces the part.
