摘要：
A novel CNC system for line contact machining is put forward to mill ruled surface efficiently. The motion control card based on FPGA is designed in the system for line contact machining. To meet the complex interpolation requirements of CNC system, NC embedded PC structure is used to improve the performance of the CNC system. Computer input and output program by C + + Builder are operated in DLL with WinIO component, to realize the communication between PC and movement control card. Three interpolation modules are simulated in Quartus II. Simulation result shows that linear interpolation, circular interpolation and complex interpolation function are realized on the motion control card based on FPGA, and the line contact machining can be realized in the CNC system efficiently.
