A milling cutter is a versatile cutting tool used in machining operations to remove material from a workpiece by advancing it into a rotating cutter. These cutting tools feature multiple cutting edges, known as teeth or flutes, distributed along the circumference or periphery of the cutter body. Milling cutters come in various shapes and sizes, each designed for specific machining tasks such as facing, profiling, slotting, contouring, and pocketing. Common types of milling cutters include end mills, ball nose cutters, face mills, and slot drills, each tailored to achieve precise cuts on different materials such as metal, wood, plastic, and composites. The selection of the appropriate milling cutter depends on factors such as the material being machined, the desired surface finish, cutting speed, feed rate, and depth of cut.
