锥基波形前刀面硬齿面插齿刀构形方法与构形理论的研究

STUDY ON THE PROFILING METHOD AND THEORY OF HARDENED GEAR PINON TYPE CUTTER WITH CONE BASE WAVE RAKE FACE

在深入剖析现有硬齿面插齿刀构形方法利弊的基础上,论述了锥基波形前刀面硬齿面插齿刀的构形方法与构形理论及其优越性。研究表明:新构形方法插齿刀较现有插齿刀构形精度可提高一倍以上,刀具主剖面负前角绝对值可提高2～5倍,刀具抗崩刃能力和整体寿命大幅度提高,完全满足高精度硬齿面插齿加工的需要。

Advantages and disadvantages of profiling method of existing hardened gear face pinion type cutter are analyzed. Based on these, the new profiling method and profiling theory is expounded emphatically and the superiority of this kind of pinion type cutter is discussed. The profiling precision raise over twice as high, the ability of breakage resistance is high but also tool life is long, the hardened gear face pinion type cutter can meet the requirements of machining of the hard face gear with high precision.
