This paper mainly is that the traditional CA6140 lathe electricity control system is Reformed the numerical control the open-loop control system. After the reform system is take the MCS-51 monolithic integrated circuit system as the control module, Take step-by-steps the electrical machinery as the actuation functional element. Realizes X axis and the Z axis two coordinates linkage as well as to the cutting tool automatic selection. At the same time can carry on the straight line and the circular arc inserts makes up; After installs the work piece Completes the multichannel working procedure the processing Completes each kind of more complex components through the compilation different procedure the processing; Enhanced the processing scope and the processing precision compared to the traditional CA6140 lathe.
