Abstract:The current situation and characteristics of superabrasive wheels dressing are recommended in this paper.Keys of superabrasive wheels dressing and dressing problems to be solved are presented.A promising dressing technique--Laser Dressing is emphasized.Study on Laser Dressing at home and abroad in recent years has been analyzed.Dressing experiments are made on resin bonded CBN wheels with opto acoustic Q switched YAG Laser.A conclusion is made that opto acoustic Q switched YAG Laser is adaptive to dress resin bonded CBN wheel.Prospects of Laser Dressing on superabrasive wheels in the future are as follows:establishment of thermohydrodynamics model;improvement on study of dressing mechanism;implementation of laser truing and dressing simultaneously;deep study on Laser Precision Dressing;development of Laser profile dressing;development of adptive controlled dressing system;implementation of on line Laser Dressing and improvement of dressing efficiency.
Keywords:superabrasive wheels  Laser Truing and Dressing  Opto  acoustic Q  switched YAG Laser  current situation  prospect
