分进给量查找计算表某些普通型和经济型数控系统没有转进给机能，而配这类系统的机床多为有级变速。在实际工作中，是以每转进给量来选取切削用量，而这类系统要求指定分进给量，在加工中，若改变主轴速度，对操作者来说，分进给不直现。当已选定主轴每分转速Ｓ和每转进给... Sub-feed to find the calculation table Some ordinary and economical CNC system does not turn into the feeding function, and with such systems are mostly multi-level variable speed machine. In practice, it is based on feed per revolution to select the cutting amount, and such systems require the specified sub-feed, during machining, if the spindle speed is changed, the operator, the sub-feed is not straightforward. When the spindle has been selected for each speed S and per revolution feed ...
