Machining Time Indicates the time that the tool is cutting Total Time This is the overall time of the process. This time is an addition of the machining time, as well as any air time that the tool makes. Replay Mode Controls how the tool paths are replayed. There are five different choices for the replay mode.

Milling is the machining process that uses a rotary cutter to remove material by moving a cutter across the workpiece. This can be done on one axis or several axes, the speed and pressure of the cutter head are in a different direction. We are going to look at some milling formulas for ease on the milling machine.
