Abstract
Burrs are formed at the workpiece edge in most metal cutting processes. These burrs cause problems in production lines in terms of added cost and time required for the deburring process. To prevent burrs, partial laser heat treatment of the workpiece is proposed. The effects of milling cutter exit angle, feed rate, and cutting speed on machined workpiece edge shape were investigated. The results indicated that the machined workpiece edge shape is affected by undeformed chip thickness and cutting time of the laser heat-treated area. In addition, by controlling the laser irradiation conditions and generating a thick martensite layer, it was possible to prevent burr formation.
