Form dressing of V-formed resinoid bond wheel by scanning a Q-switched YAG laser beam on the wheel surface is carried out and the form dressing mechanism is experimentally investigated by analyzing initial profile of dressed wheel, variation of wheel tip profile in form grinding process, density and height of cutting edge and so on, comparing with those by a traditional dressing with PVA wheel. Main conclusions obtained in this paper are as follows; (1) Scanning YAG laser beam on V-formed resinoid bond wheel surface results in the better form dressing effect concerning form accuracy or projecting height of cutting edge than a traditional dressing with PVA wheel. (2) Radius of wheel tip decreases with increasing peripheral wheel speed in form dressing because a heat effect on wheel surface by laser beam decreases with an increase of peripheral wheel speed. (3) Laser dressing of V-formed wheel at higher peripheral wheel speed represses a reduction of form accuracy in form grinding process. (4) Radius of dressed wheel tip increases with increasing formed angle and is much affected at larger formed angle by peripheral wheel speed in laser dressing.
