车削加工中的刀具磨损问题长期以来一直引起人们的普遍关注。这不仅因为刀具本身的成本将影响总的加工成本,而且因为刀具的更换增加了机床辅助时间,在生产效率极大提高的今天,后一因素对总的加工成本有更大的影响。刀具的磨损率是切削用量提高的一个主要制约因素,而它们又共同决定着总的加工成本(当然还有其它一些影响因素)。因此,如何确定一个最为合理的切削 Tool wear in turning has long been a cause for widespread concern. This is not only because the cost of the tool itself will affect the total cost of processing, but also because the replacement of tools increases the machine aided time, which greatly affects the total processing cost. Tool wear rates are a major constraint on increased cutting usage, and together they determine the total processing cost (and of course other factors). Therefore, how to determine a most reasonable cutting
