刀具磨损形式有哪几种：什么是刀具的耐用度？什么是刀具的寿命？

切削液能从切削区域带走大量的()，降低刀具、工件温度，提高刀具寿命和加工质量。

什么叫刀具耐用度？什么叫刀具寿命？

什么是刀具的耐用度？它和刀具的寿命有什么关系？

切削用量对刀具寿命的影响，主要是通过切削温度的高低来影响，所以影响刀具寿命最大的是：（）

超精密切削是使用精密的（）刀具切削加工金属和非金属材料。

Every deliberate act of wrongdoing by the master or any of the crew against the ship or cargo，without the authorization or privity of the Shipowner or his agent，is（）.

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

刀具磨损越慢，切削加工时间就越（），也就是刀具寿命越长。

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。
