【Abstract】 A new trace controlling technology is developed in order to meet the demands in development of domestic high speed and high precision CNC machine tools. The tool motion trace is generated by high frequency and high resolution sampling and interpolating,the expected trace can be realized correctly by new type full close loop position control, the system is effectively integrated by digital information transfer. Such design of high poed and high precision trace controlling system has been applied to various domestic CNC machine tools and it works very satisfactory.更多还原
