Cemented carbide cutting tools cutting layer parameters

Cutting layer of the cemented carbide cutting tools is the workpiece material layer to cut through the removal of the workpiece in a single pass of to the cutting portion. Cutting layer shape, size directly affects the deformation of the cutting process, the tool bear the load as well as the cemented carbide cutting tool wear. As shown, when the main and auxiliary cutting edges is straight, and λs = O °, KR> 0 °, the cutting layer to the nominal cross section ABCD is a parallelogram, if Kr = 90 °, or rectangular.
