Cemented Carbide Cutting tool Boundary Notch

Boundary notch of the cemented carbide cutting tool can be expressed by boundary notch height and boundary notch width. The forming processes of boundary notch can be divided into three steps: micro-tipping appears firstly; then,mesh fractures expand; finally, boundary notch results.

Main factors that influence boundary notch of cemented carbide cutter are pieces material,cutter material and cutter geometry parameters.

Deburring machining process and adjusting cutting tool geometry parameters to reduecce angle and width of negative chamfer, to increase cutter corner that ensures thae quality of workpiece and cutting performances of cutting tool.
