某斜齿轮零件由于结构上的原因,只能采用如图1所示的斜梳齿刀。刀具工作时,刀具的节线（或齿顶线）与零件轴线相垂直,且沿着零件螺旋角作上下运动,从而加工出所需的齿型面。
A bevel gear parts due to structural reasons, can only be used as shown in Figure 1 oblique comb tooth cutter. When the tool is working, the knuckle (or tip line) of the tool is perpendicular to the axis of the part and moves up and down along the helix angle of the part to produce the desired tooth profile.
