砥石摩耗特性

This paper presents the experimental investigation on the wear characteristics of CBN wheels in creep feed grinding. The obtained results are as follows : (1) As the wheel depth of cut decreases at a constant stock removal rate, the grinding force per a grain cutting edge f_ts increases almost power functionally and the mechanism of wheel wear changes rapidly from the attrition type to the micro-fracture type when the f_ts value exceeds a critical value f_ts (c). (2) The volumetric wheel wear rate takes a minimum value at the critical condition.
