End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour Milling machines can be used on wood, metal, and nearly any other solid object to cut a range of shapes and sizes They are most often automated by computer numeric control to carve out designs created in a computer-aided design program, but manually operated machines are also still common Milling machines can be used in both horizontal and vertical
