摘要：不等螺旋角立铣刀的切削刃有不同的螺旋角，通过切削试验对比不对称不等螺旋角立铣刀和传统等齿距立铣刀、对称式不等螺旋角立铣刀的切削性能。试验结果表明：与传统等齿距立铣刀相比，不等螺旋角立铣刀显著降低了切削过程中的振动，对称式不等螺旋角立铣刀切削力小于不对称不等螺旋角立铣刀，在加工薄壁零件时，不对称的不等螺旋角立铣刀能够获得比普通不等螺旋角立铣刀更好的表面质量。

Abstract: Each cutting edges of unequal helix end mill is provided with variablet helix angle.Through the cutting experiment，compared with traditional end mills，unequal helix angle end mills and ordinary unequal helix angles end mills.The experimental results show that unequal helix angles end mills can significantly reduce the vibration in the cutting process compared with the traditional enqual pitch end mills，especially when the thinwalled parts are processed，the unequal helix angle end mills can obtain better surface quality than the common unequal helix end mills.
