切削参数对弧齿锥齿轮齿面平均残余高度的影响

基于弧齿锥齿轮展成加工原理，推导了各数控（NC）轴运动表达式，研究刀盘转速、数控轴联动速度和单步插补角度等参数对齿面平均残留高度的影响规律，建立了两者之间的耦合关系，在此基础上完成了切齿验证试验。结果表明:在降低齿面平均残留高度方面，刀片旋转切削速度的改变影响很小，数控轴联动移动速度的影响略有增加，单步插补度数的影响最为显著，实验结果和理论分析结果一致，验证了本文理论的正确性。 

Effect of cutting parameters on average scallop height for tooth surface of spiral bevel gears

Based on the spiral bevel gear finish milling theories conducted by the numerical control(NC) face milling method, the expressions of motions for the NC axes were deduced, the influencing patterns of cutting speed, rate of movement of linkage axes, and degree of single step interpolation on the average scallop heights were studied, and their coupling relations were setup. Accordingly, the cutting experiment was conducted to verify the above results. The proposed study indicates that increasing the cutting speed and the rate of movement of the linkage axes has limited effect on average scallop height, while decreasing the degree of single step interpolation is able to reduce the average scallop height dramatically, which agrees with the theoretical analysis.
