A high-efficiency milling strategy using a small radial engagement and a very deep axial cut.
The cutter follows a looping path that keeps radial engagement low — often under 10% of diameter — while taking an axial cut as deep as the flute length. The low radial engagement thins the chip, and the feed is raised to compensate.
The result is a much higher material removal rate for a given spindle power, because the cutting force is spread along more of the flute and less of the tool is engaged at any moment. It needs a fast control and a rigid setup.
Using trochoidal paths at the conventional feed per tooth. The thinned chip means the tooth rubs instead of cutting unless the feed is raised.
