等螺旋角锥形立铣刀容屑槽槽形的理论分析

Theoretical Analysis of Chip Flute of Spiral Taper Milling Cutter with An Equal Helical Angle

本文研究了等螺旋角锥形立铣刀容屑槽的槽形特点及其形成方法,推导了槽形的理论计算公式并编制了相应的计算机程序,利用该程序可以在进行实际的切削加工前,在计算机上绘制其加工槽形,并计算前角、刃带宽度,有利于正确地选择二次刀具及调整参数。

This paper discusses the charateristics of the chip flute of spiral taper milling cutters with an equal helical angle, and the way how to produce it. The theoretical calculation formulas were derived and pro-grammed and so the chip flute can be charted on a computer with the rake angle and cutting edge width worked out before manufacturing. This is useful for choosing correctly the cutter to be used in the machining of spiral taper milling cutters.
