Research Abstract

The major aim of the present research project is to contribute for establishing a new method of in-process sensing/monitoring tool wear especially in turning process. After various experiments are carried out, following results are obtained.
1. The close correlations between flank wear of cutting tool and the transient vibration generated by a diagnostic impulse are confirmed for plain carbon steel (S35C) /general purpose cast iron (FC20).
2. For this in-process sensing method, the cutting tool is necessarily clamped firm. The fixing torque of the clamp screw must be over than 15Nm for ordinary case.
3. Improving controllability and accuracy of the amplitude of the diagnostic impulse, a newly designed small electro-magnetic hammer is introduced and tested. The resultant variation of the impulse are limited only several % for the selected conditions.
