Cutting tools are vital instruments in the machining and manufacturing sectors, designed to remove material from a workpiece through processes such as cutting, shearing, and grinding. These tools come in various types, including single-point tools like lathe and boring tools, and multi-point tools such as milling cutters and drill bits. The material composition of cutting tools significantly influences their performance and durability, with common materials including high-speed steel (HSS), carbide, ceramics, cubic boron nitride (CBN), and diamond. Each material offers unique properties suited to different applications, from high-speed machining to precision cutting of hard or abrasive materials. Cutting tools are extensively used across industries like automotive, aerospace, medical devices, construction, and electronics, each requiring precise and efficient machining capabilities. Proper maintenance, such as regular sharpening and appropriate selection of cutting parameters, is crucial to maximizing the lifespan and performance of cutting tools. Technological advancements, particularly in tool coatings, have further enhanced their wear resistance and overall effectiveness, driving innovation and efficiency in manufacturing processes.
