Microtexturing has emerged as a highly effective technique for enhancing the performance of carbide cutting tools by precisely altering their surface characteristics at the microscale. Strategically designed microtextures can significantly improve the tribological behavior of cutting tools by reducing friction, facilitating efficient chip evacuation, and minimizing tool wear during machining operations. Practical implementations have demonstrated notable improvements in tool life, machining efficiency, and the surface finish of workpieces. This chapter presents an overview of microtexturing on carbide cutting tools to enhance machining performance. It discusses the fundamental principles, methodologies, and performance outcomes associated with surface texturing techniques applied to carbide cutting tools.
