Tungsten Carbide Hand Cutting Tool Rake

For a tungsten carbide hand cutting tool involved in axial milling, there are several rake angles to be addressed, all addressing cutting forces for a given material. Side rake is relative to cutting edge. With positive tungsten carbide hand cutting tools the rake is in the tool, for negative tools, the rake is relative to the position of the tool to the center line. Since there’s no clearance in negative inserts, clearance is provided by normally having a 5 to 7 deg negative rake and side rake for clearance to avoid rubbing.  Shear plane is recognizing as the shearing of metal at a given plane, that is relative to the cutting edge.  A negative plane offers less shear, more pushing of the material, more horsepower and a stronger edge engaged in the cut zone. A positive plane reduces cutting forces offers freer cutting, less horsepower and a weaker cutting edge. Clearance is the angle below or behind the cutting edge.
