Design and Analysis of the Special Milling Machine CNC System based on MCU

Computer control system is the hardcore of milling machines,which is applied to input digital parts program,memory the inputted information,transform data and interpolate operation so that it could realize all kinds of controlling functions.The design of the special milling machine CNC system must be taken consideration into the matching of hardware and must be realized from economic,practical and feasible aspects.The control system with PIC MCU was taken as the main body,which was prone to realize the effective control function in the hardware design and the construction is relatively sim-ple.On the software design,the CNC system can realize the control to the running direction and speed of the milling machine by the formation of interpolation,so that it is applied widely in the special milling machines.
