This research examines the benefits of localised workpiece heating in metal machining with a laser source for reduce cutting forces and improve machinability. The study develops a three-dimensional numerical model for laser preheating on a rotating metal cylinder with experimental validation to evaluate thermal response and strong correlation between heating levels and metal cutting parameters. The research outcomes are directly applicable to hard metal machining such as titanium alloys in manufacturing industry.
