摘要:

提出了加工非可展直纹面刀轴矢量的解析解法,给出了解析解法的加工误差,并将其与“R偏置法”的侧铣加工方法的误差进行了比较。计算结果证明,该方法减小了理论误差。应用MATLAB绘制了依据该方法计算出的叶片刀轴轨迹。最后,通过数控加工试验验证了所提出方法的正确性。加工结果表明,加工误差在允许加工误差范围内,叶轮加工表面质量好。

关键词: 侧铣, 非可展直纹面, 解析法, 加工误差

Abstract:

This  paper  proposed machining non-developable ruled surface cutter axis vector's analytical method,provided the  analytical method's machining error and  compared with the “R offset” flank milling method's error.The results prove  that the  prposed  melhod   can reduce the theoretical errors.Then the blade tool path trajectory  was drew   by the algorithm with MATLAB software. Finally,NC machining experiments verified the proposed algorithm,the machining results show that the machining errors are  within the allowable machining error range and the  machining surface quality of impeller is good.

Key words: flank , milling;non-development ruled , surface;analytical , method;machining error
