Abstract
A method of determining the size distribution of grinding-induced cracks using a simulation of the grinding process is presented. The simulation uses the grinding wheel profile, grinding conditions and the normal grinding force as input. The grinding operation is considered to be a continuous indentation process arising from a series of abrasive edges. The grinding-induced cracks are estimated based on the indentation fracture mechanics model. Applying the simulation procedure to creep feed grinding of alumina with resinoid diamond wheels resulted in estimates of crack sizes ranging from 3 to 37 μm for the four different grinding conditions that were used in the study.
