Diamond and cubic boron nitride abrasive abrasive damage threshold

Laser trimming method as a non-contact method of dressing, avoid hard contact force and is a promising method for trimming, but there is a big gap from the practical application, abrasive grinding study. In order to promote the laser trimming technology practical application, the paper made ​​the following tasks: (1) to establish a computing laser dressing threshold dimensional unstable heat conduction model, the differential  grinding wheel , programming operations, solving a single pulse laser irradiation resin bond and metal binder removal threshold,  Diamond blade boron nitride abrasive abrasive damage threshold for the selection of a suitable laser dressing parameter provides the basis. (2) Single pulse ablation pit size and depth of the sharpening effect plays an important role.
