本刊上期介绍了庄铭耕同志做好生产前的准备工作,和缩短辅助工时的无针校正法的经验,现在继续介绍他的经验,供大家学习参考。(二)分段作业一个工件,从加工开始到加工完毕,一般都要几次更换刀具、测量和调速等,将这些时间加起来,就形成了很多的辅助时间,大约要占全部加工时间的30～40%。庄铭耕针对着这个问题,采用了分段作业,将一批工件的工序分成几段,使繁杂的加工步骤变得简单。但是这样做要增加装拆工件的次数,同时
In this issue, Comrade Zhuang Minggeng introduced the preparatory work prior to production and the experience of shortening the needle-free correctional law of assisted working hours. Now, I will continue to introduce his experiences for reference. (B) a piece of work A piece of work, from processing to the completion of the processing is completed, usually several times to replace the tool, measurement and speed control, these time together, it formed a lot of auxiliary time, accounting for about all the processing time Of 30 to 40%. Zhuang Minggeng aiming at this problem, using a segmented operation, the process of a number of pieces of the workpiece is divided into several sections, so that complicated processing steps become simple. However, this will increase the number of loading and unloading parts, at the same time
