Abstract

In this report the fundamental analyses of grinding phenomena in very low speed grinding process have been considered in order to investigate the possibility of high accuracy and high quality machining. Main conclusions are as follows : (1) Observation of cutting chips shows that continuous chips are generated in very low speed grinding as same as ones generated in common speed grinding. (2) At wheel speed Vs=14m/s the unique phenomena of wheel wear rate and grinding forces are due to the size effect caused by the change of wheel wear condition. (3) The grinding performance of accuracy and quality at very low wheel speed Vs=0.5m/s is equal with and/or more excellent than that in common speed grinding.
