Abstract
Experiments have been made to study self-excited vibration in cylindrical grinding. The results are as follows : (1) Remarkable vibration with considerably large amplitude occurs in higher work speed range, in plunge grinding always and in traverse grinding at considerably smaller feed as compared with the wheel width. (2) The frequency of the vibration relates with the natural frequency of bending vibration of the work. (3) Spiral chatter marks are generated in traverse grinding.. (4) The work vibrates almost in line with the resultant grinding force. It is concluded from the experimental results that the self-excited vibration due to regenerative effect occurs in cylindrical grinding.
