Machining of hardened steel components has traditionally been the domain of grinding. A laser-assisted machining (LAM) process with a larger material removal rate is developed to replace the currently used hard turning and grinding operations for machining hardened steel shafts.
Novel laser-assisted machining techniques were exploited for profile finishing of difficult-to-machine materials of complex geometric features. The study of laser-assisted machining was based on a simultaneous experimental and numerical investigation of the process.
