摘要
在细长轴车削加工中,通过建立线阵CCD(Charge-Coupled Device)测量系统和PID(Proportion-IntegralDerivative)误差控制系统组成的在线实时检测控制系统,应用线阵CCD测量系统对工件直径进行在线实时检测,并将测得的结果及时传输到PID误差控制系统,经分析计算后将误差大小反馈给数控系统,数控系统通过刀具的切削补偿来控制整个切削过程.通过试验对比分析,其结果与实际车削加工相符,证明了该系统能够显著提高加工精度,对细长轴实际车削加工具有指导意义.
During the slender shaft turning process, an on-line and real-time detection and control system is established using the linear array CCD measurement and PID error control systems. With the CCD measurement system for work-piece diameter detection, the results are transmitted to the PID error control system. By feeding the errors back to the NC system, the machining compensations are used for machining process control. In comparison with the experimental and actual results, the machining precision is significantly enhanced for slender shaft turning.
