Microwave hybrid heating is an efficient method of heating that combines traditional heating techniques with the power of microwaves. In this study, microwaves have been utilized to modify the mechanical properties of tungsten carbide (WC/Co) cutting tool inserts by enhancing the microhardness and wear resistance properties. This result improvement in microhardness is expected to ease the cutting process and reduce tool wear. This research will involve conducting experiments, including assessing the microhardness and tool wear measurement by comparing the performance of microwave-treated tool inserts with untreated tool inserts. The findings from this study could have implications for the manufacturing industry as they offer a solution to enhance machining processes for high-strength materials while prolonging the lifespan of cutting tool inserts. The improved efficiency and reduced costs associated with replacing tools will be among the outcomes obtained from this research ultimately contributing to advancements, in metal-cutting technology.
