Milling is a popular machining process. Milling is a machining operation in which a revolving cutter removes material from a workpiece in a controlled manner. This method of subtractive manufacturing seeks to give the workpiece the desired shape. In milling operations, rotary cutting tools, typically equipped with multiple teeth or edges, …
