Structured and textured cutting tool surfaces for machining applications

In the past few decades, there has been considerable advancement in developing and testing structured and textured cutting tools for different machining operations. This paper not only presents a review of the stateof-the-art in manufacturing processes to structure and texture surfaces of cutting tools for machining applications but also identifies the strengths and weaknesses of utilizing structured or textured rake and flank faces as well as other important functional surfaces of cutting tools. This includes an assessment of the relevant texture geometries and microscale structures and their applicability and/or limitations for the improved chip material flow and contact at the chip-tool interface, reduced forces, dynamic deflections, and friction, improved anti-adhesion and tool wear, and enhanced debris management, lubricant, and coolant utilization. This manuscript includes contributions from many research groups in academia who closely work with industry and the content presented herein is expected to provide an organized and comprehensive narrative on current advances, capabilities, and challenges in developing and implementing optimum texture and structure design on cutting tool surfaces with some guidance for future directions.
