In drilling fluorophlogopite,the wear width on major flank was measured and the material removal volume was calc-ulated.The wear width per material removal volume(VB/V) was applied to evaluate tool wear in this test.Through single factor test,some machining parameters were discussed such as tool material,cooling conditions,spindle speed and tool angle.The test results show the tool wear rate is mainly affected by tool material and cooling conditions.During fluorophlogopite ceramics machining,the high-speed ...
