摘要
通过采用Renishaw QC20-W无线型球杆仪对某立式加工中心的XY,YZ,ZX三个平面在不同的进给速度下圆度误差进行了测试,对不同进给速度下的圆度误差进行了对比和分析。最后通过分析机床各项因素对圆度误差的影响,得出了造成伺服轴圆度误差的主要原因是由于伺服不匹配和垂直度误差,给出了改进伺服轴位置环增益等建议。
The roundness error test using Renishaw QC20-W wireless ballbar for a certain type of vertical machine center's XY,YZ,ZXplane.The roundness errors at different feed speeds are compared and analyzed.Finally,through the analysis of various factors influence on machine roundness error,the main cause of the servo axis roundness error is due to the servo mismatch and verticality error,and the improvement of servo shaft position loop gain is proposed.
