Milling uses rotary cutters to remove material from a workpiece by feeding the workpiece at an angle to the axis of the tool. The axes that a milling machine has, determines the type of work and the locations in which it can be done on the workpiece. Here we look at 3, 4, and 5 axis machining, their differences, and which to choose for your part.
