在现代金属切削加工中,为提高劳动生产率,常常采用提高切削用量的方法。然而,随着切削用量的提高,切削刀具的耐用度将随之降低,换刀、调刀次数将随之增多,换刀调刀时间在切削加工工时中所占的比重将相对增大。因此,改进调刀技术、缩短调刀时间、提高调刀精度,对提高切削加工,特别是镗削加工的生产效率,具有非常重要的意义。
In modern metal cutting, in order to improve labor productivity, cutting methods are often used to increase the amount of cutting. However, as the amount of cutting increases, the durability of the cutting tool will be reduced. The number of tool changing and cutting times will increase accordingly, and the proportion of tool changing time will be relatively increased. Therefore, it is very important to improve the tool setting technology, shorten the tool setting time and improve the precision of tool setting. It is very important to improve the production efficiency of cutting, especially boring.
