State of the Art Laser Dressing System for Super Abrasive Grinding Wheels

Conventional dressing methods available commercially are single point and roller dressers. Dressing is essentially a sharpening operation designated to generate a specific topography on the working surface of the grinding wheel. These techniques have seldom been satisfactory for super abrasive wheels. There are problems of high dresser wear, insufficient grain protrusion, improper generation of profiles, stresses being induced into wheels, time consuming, shortcomings of loading induced deformation&shape distortion and very low dressing efficiencies. Numerous works have been published on the feasibility of laser dressing of grinding wheels till now. Based on the reports and research works, the present effort has been to actualize the same conditions of laser dressing in actual high speed grinding conditions. The work presents a favourable and opportune environment for the technology of laser dressing to shape into reality.
