新构形硬质合金插齿刀切削刃几何角度分析

Analysis of Geometric Angle of Cutting Edge of New Profiling Carbide Shaper Cutter

提出了一种硬质合金插齿刀的新构形方法———异形凸曲前刀面硬质合金插齿刀,对新构形插齿刀的前角、后角及刃倾角进行了分析;建立了切削刃几何角度的数学模型,与原构形硬质合金插齿刀进行了比较研究。

A new profiling method(carbide shaper cutter with complicated curved rake face) is presented. The rake angle, cutting clearance and edge rake angle of the new profiling carbide shaper cutter are analyzed. The mathematical model of geometic angle of cutting edge is established. The comparing study between new profiling and traditional method is acted.
