For NC machining of plane section method, the machining path of toolcuttingplane and implicit surface can be found, and the curve of the tool path is drawn by the positive-negative method.
Because there exists a chip-curling groove on the rake face, the rake face of a modern cuttingtool used on NC machine tool is not a plane, but a curved surface.
由于现代数控刀具都设计有卷屑槽,从而使其前刀面不是平面,而是曲面。

Is processed the plane is the big plane, the material is HT250, therefore cuttingtool choice hard alloy face cutter.
