CM202 数控机床精度的要求现在已经不局限于静态的几何精度,机床的运动精度、热变形以及对振动的监测和补偿越来越获得重视。
(1)提高CNC系统控制精度:采用高速插补技术,以微小程序段实现连续进给,使CNC控制单位,并采用高分辨率位置检测装置,提高位置检测精度(日本已开发装有106脉冲/转的内藏位置检测器的交流伺服电机,其位置检测精度可达到0.01μm/脉冲),位置伺服系统采用前馈控制与非线性控制等方法;
(2)采用误差补偿技术:采用反向间隙补偿、丝杆螺距误差补偿和刀具误差补偿等技术,对设备的热变形误差和空间误差进行综合补偿。研究结果表明,综合误差补偿技术的应用可将加工误差减少60%~80%;
(3)采用网格检查和提高加工中心的运动轨迹精度,并通过仿真预测机床的加工精度,以保证机床的定位精度和重复定位精度,使其性能长期稳定,能够在不同运行条件下完成多种加工任务,并保证零件的加工质量。
