Abstract
The variation of cutting force exerted on a cutting edge in grinding wheel-workpiece interface is analyzed theoretically by a statistical approach, and the mean cutting area a of a cutting edge and the normal grinding force F exerted on a small part in the wheel-workpiece interface are derived. Through the theoretical analysis, it is revealed that the normal grinding force F, which rises linearly from the starting point of cutting, takes the maximum value immediately before the end of cutting, and that the maximum value Fm of F is proportional to the maximum value fm of mean cutting force f which is exerted on one cutting edge and can be assumed to be proportional to a. The variation of normal grinding force F, which was measured by some experiments, agreed well with the theoretical one.
