大前角圆弧铣刀齿形修正拟合

Modification and match of big orthogonal convex or concave milling cutter's profile

主要介绍圆弧铣刀在大前角情况下,齿形的修正计算及运用椭圆方程拟合圆弧铣刀前刃面齿形,有效提高了圆弧铣刀制造精度,满足了对高精度圆弧的加工要求。

Design of the big orthogonal convex or concave milling cutter＇ s profile, and profile modification are introduced. By using ellipse formula to match the arc of face profile, the manufacturing requirements for highly accurate arc are satisfied.
