Abstract

Laser treatment is a novel and promising non-conventional method to reduce the conditioning costs and time of superabrasive tools. In this study, the thermal effects of picosecond laser radiation on metal-bonded cubic boron nitride (CBN) and diamond superabrasive tool surfaces have been analytically and experimentally investigated. The analytical approach is intended to find threshold process parameters for the selective ablation of the superabrasive grains and the bond material. The laser radiation experiments have been conducted with a picosecond Yb:YAG laser on metal-bonded CBN and diamond honing tools. It has been analytically and experimentally demonstrated that, using suitable parameters, the selective and controlled treatment of superabrasive tool components is possible.
