Research output: Contribution to journalArticlepeer-review


Ductile mode grinding can be applied to ceramics if the grain depth of cut is decreased. In this research, single grain grinding experiments by using a pyramidal diamond tool have been carried out in order to clarify the ductile brittle behavior for 4 kinds of sintered ceramics. The results are as follows. (1) For the ground grooves of ceramics, shallowing effect by elastic recovery is not recognized. (2) The ratio of height of pile up peak to groove depth decreased with increasing maximum grain depth of cut gm. (3) While the formation of ground grooves changes from ductile mode to brittle mode with increasing gm, the pile ups of both sides of ground grooves coexist with chipping in the transition region. (4) In the brittle mode region for SiC and Al2O3, the actual groove depth was larger than the set value. (5) With ductile mode grinding, the height of formed peak between two grooves approximately agrees with the geometric value.
