另部件加工时,大直径的电测,在国内一直是一个未解决而又极待解决的问题。利用单位增量脉冲计数的方法,进行大直径的电子测量,可以完全取代传统的大卡尺的机械测量。大直径的电测又是数控和群控机床进行自动加工中必须解决一个课题。这一方法的基本原理已在有关杂志上介绍过了。经过几年来的试验研究,现提出一种较完善 Another part of the processing, the large diameter of the electrical measurement in the country has always been an unsolved problem to be solved. The use of incremental pulse counting unit method for large diameter electronic measurement, can completely replace the traditional mechanical caliper measurements. Large diameter electrical measurement is CNC and group control machine automatic machining must solve a problem. The rationale for this approach has been introduced in magazines. After several years of experimental research, it is proposed a more perfect
