Because of the use of larger radial rake angles and the unique geometry, the chips are easily deformed and the side walls remain perpendicular.
Inside economical milling: an expert looks at all the angels. (Cover Story)
Positive radial rake cuts softer and with less pressure, using less horsepower, creating less heat, and resulting in less strain on machine bearings, ways, and spindle." He compares positive-geometry milling to a planer on wood, where the work material is lifted up and peeled off.
The power of positive inserts
There has been a progression in the geometry of milling cutters from negative axial rake/negative radial rake to positive/positive configurations and, more recently, to High Positive configurations-so called because of greater than normal rake angles, i.e., typically 10 and 10 deg.
Milling cuts it better
Negative radial rake provides strong cutting edges, while positive rake creates a shearing action.
