在滚刀制造过程中,由于滚刀螺旋角大,刃磨前角时会产生严重干涉现象,使前面产生腰鼓形和齿顶部塌角(如图1)。这种由于干涉而形成的曲线,计算复杂,难于找出它的曲线方程。因此,磨大螺旋角滚刀前角时,如何正确修整砂轮,消除干涉,是个比较困难的问题。目前,一般工厂的操作师傅,为了消除干涉,使前面平直,基本上都是利用折尺或徒手凭经验多次修整砂轮,反复测量滚刀前面, In the hob manufacturing process, due to hob helix angle, sharpening rake will have a serious interference phenomenon, so that front of the waist drum and tooth top collapse (Figure 1). The curve formed by the interference is complicated to calculate and difficult to find its curve equation. Therefore, when grinding the large helix angle rake angle, how to properly adjust the wheel, to eliminate interference, is a more difficult issue. At present, the operation of the general factory master, in order to eliminate interference, so straight in front, are basically using folding ruler or free hand experience dressing wheel several times, repeatedly measuring the hob in front of,
