关于螺旋槽加工和刀具截形设计,已有成熟资料。当对螺旋槽形精度要求不严时,常用单角度铣刀加工;但若所加工的螺旋角较大,则易出现槽形和前角不符要求,乃至报废。本文针对这一问题从理论上推导了用单角度铣刀加工螺旋槽的端截形方程,经实际验证,可直接用于生产。 There are well-documented sources of helical groove machining and tool truncation design. When the accuracy of the spiral groove is not strict, single-angle milling cutter is often used. However, if the helix angle to be machined is large, the groove shape and the rake angle may not meet the requirements and may even be discarded. In view of this problem, this paper theoretically deduces the end truncation equation of helical groove machining with a single angle milling cutter, which can be directly used in the production after the actual verification.
