摘　　要：介绍了以高频高分辨率采样插补生成刀具运动轨迹,通过新型转角-线位移双位置闭环控制保证轨迹具有所希望的精度,并以信息化轨迹校正消除机械误差和干扰对轨迹精度的影响,从而保证机床长期高精度运行。Sampling interpolation with high frequency and resolution is used to generate cutter movement trajectory, via new type angle of rotation-linear displacement two-position closed loop control, so as to ensure expected accuracy, and also informatization trajectory is used to correct and eliminate the effect of mechanical error and interference with trajectory accuracy, thereby to ensure the high accuracy running of the machine tool in long term.
