The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.
Cammilling is the operation of production of cams in a milling machine by the use of a universal dividing head and a vertical milling attachment. The axis of the cam blank and the end mill spindle should always remain parallel to each other when set for cam milling.
