Realization of convenience and can guarantee a certain accuracy. Reduce costs, computer control technology is the most simple application. It full use of the software hardware crisis To achieve the functions of the machine control; to expand the scope of the processing machine tools, precision and reliability has been further improved. XY NC table is the use of mechanical and electrical systems design SCM 8031, 2764,6264 and 8155 and memory chips and other hardware components , In the control system of hardware on the preparation of certain procedures in order to achieve a certain processing functions. The basic idea is: circular or linear interpolation procedures to achieve the geometry of the parts for processing, every section of the processing should have a certain impulse to Electric drives positive and, through 8155 (1) corresponding to the processing of information sent to the turret into the knife in order to achieve the corresponding go to the knife, the electrical and tool to achieve the relative movement of the tool so the processing of the workpiece. The control system uses software interrupt control system structure and subroutine is simple, clear in the economic conditions in the application of NC more. Disruption of a modular structure because such a structure designed to facilitate revision and expansion, the establishment of more convenient, easy to handle and more direction. CNC XY table designed by mechanical and electrical systems as a stepping motor-driven devices. Stepper motor is a pulse will be transferred into angular displacement of the Electrical and Mechanical-DAC devi
