CNC Applications - University of Florida

machine was a joint project between Massachusetts Institute of Technology (MIT) and the US Air Force in the mid 1950's. It was a three axis milling machine controlled by a room full of vacuum tube electronics. Even though it was unreliable, it set the stage for modern machines. The controller was called Numerical Control, or NC.

predominant noise sources in the workrooms of the mill. The causes of high noise in the rice mills may be attributed to the use of a long flat belt drive, crank-and-pitman mechanisms, absence of an electric motor enclosure, poor machine maintenance and inadequate acoustic design of the workroom of the rice mill (Prasanna Kumar et al., 2008).

Milling Machine - University of Minnesota

The cutting action of the milling machine is performed by the endmill or drill bit when it rotates. The endmill and drill bit are sharp. The cutting action produces material chips that could be sharp. These chips may be propelled into the air by the rotating motion of the milling machine and cause injury. Control Plan:
