近几年来,经济型数控车床使用日益广泛,它不仅为使用单位提高了经济效益,而且为普车的技术改造起了一定的示范作用。但是笔者在调查中也发现投产不久的经济型数控车床因操作者嫌操作麻烦,不愿使用而处于闲置状态的也为数不少,此类问题不解决,势必会影响到数控车床的进一步推广和普及。一、存在的问题及其分析操作者反映得较集中的问题有二: 1.加工前刀具的起始位置(程序原点)调整困难批量大调整一次还值得,批量小还不如使用普通车床。所以该问题的实质就是如何在加工中实现坐标设定功能。 2.换刀时刀位校准困难在数控车床上一般零件的加工都不是一把刀具所能完成的,为此都设置了自动转位刀架和刀位补偿功能。但由于刀补量的测量
In recent years, the economical use of CNC lathes is more and more widely used. It not only improves the economic benefits for the units used, but also plays an exemplary role in the technological transformation of the general car. However, the author also found in the survey put into operation near the economy of CNC lathes because operators are too bothersome to operate, are unwilling to use and in a lot of idle state, such problems are not resolved, is bound to affect the further promotion of CNC lathes and universal. First, the existing problems and their analysis The operator has two problems that are more concentrated: 1. The starting position of the tool before machining (program origin) is difficult to adjust Large batch adjustment is also worthwhile. So the essence of the problem is how to realize the coordinate setting function in the process. Tool change when the knife bit difficult to calibrate the NC parts in the general machining of the lathe can not be completed by a tool, for which have set up an automatic indexing knife holder and cutter compensation. However, due to the amount of knife measurement
