一、前言为了改善切削条件,有些成形铣刀的前角设计成大于零度。当成形铣刀有了前角后,刀齿在轴向剖面内的廓形,就与被加工零件的端面廓形不相同了。因此,成形铣刀在制造过程中,需要求出成形铣刀刀齿的轴 First, foreword In order to improve the cutting conditions, some shaped cutter angle is designed to be greater than zero degrees. When the forming cutter with the rake angle, the tooth profile in the axial section, and the machined parts of the end profile is not the same. Therefore, the forming milling cutter in the manufacturing process, you need to find out the axis of the milling cutter teeth
