| 摘 要： | 直线电动机作为高速数控机床直接伺服进给系统驱动方式，得到广泛应用．设计了基于PMAC的直线电动机伺服进给驱动单元．该伺服进给机构将直线电动机、高速电主轴、直线光栅尺、LUGE动板以及其它附件集成在一起，实现了数控磨床横向工作台和砂轮主轴系统的”零传动”．研究了直线电动机的双闭环控制技术和定位精度等问题．通过对动板有限元分析表明，电主轴压力产生的垂直变形量不会对系统运行精度产生影响；实验研究了电主轴振动和直线电动机伺服刚度对定位精度的影响，探讨了PMAC的误差补偿功能．表明该系统具有良好的动态性能以及定位精度．

| Abstract: | Linear motor as a novel driving mode is widely applied in feeding system of high-speed CNC.Based on the PMAC,the servo feed unit driven by linear motor is designed in this paper.By combining the linear motor,high-speed spindle,linear raster,LUGE table and their accessories in this unit,"zero transmission" between the worktable and wheel spindle in the numerical control grinding machine is realized.The results analyzed by FEM show that the influence of the distortion due to spindle pressure on systematic ope... |
