Abstract

The purpose of this study is to establish a new dressing technique of resinoid bond wheel by scanning the point of heat source on wheel surface. Dressing effect with CW YAG laser is testified in previous report. In this paper, Q-switched YAG laser is selected as a dressing tool for making more improvement of dressing effect with YAG laser, and dressing mechanism and grinding characteristics of dressed resinoid bond wheel with Q-switched YAG laser are experimentally discussed by observing the acting wheel surface and analyzing some grinding results with dressed wheel. Furthermore, dressing effect with Q-switched laser is verified by comparing with that with CW laser. Main conclusions obtained in this paper are as follows : (1) Scanning Q-switched YAG laser beam on resinoid bond wheel surface results in better dressing effect than that with CW laser beam. (2) Dressing with Q-switched laser of 2kHz in Q-switch frequency brings out best grinding characteristics of resinoid bond wheel in those of all Q-switch frequency. (3) In lower Q-switch frequency, heat affected structure generated on dressed wheel surface is completely removed as soon as laser beam is irradiated because of radical and frequent variation of heat energy supplied with laser beam.
