【摘要】：针对螺旋锥齿轮在数控加工中心上加工效率低的问题,提出利用盘状铣刀对螺旋锥齿轮进行端铣的加工方法。由螺旋锥齿轮齿面及刀具的几何特征,调整铣刀与被加工齿面的相对位置,使齿面与刀具包络面的法截面相对法曲率最小,增大切削带宽,同时控制刀轴矢量调整切削深度避免加工干涉。最后将规划的加工刀位转化到数控机床轴上,利用VERICUT进行加工仿真验证该方法的可行性与正确性。
[Abstract]:Aiming at the problem of low machining efficiency of spiral bevel gear in NC machining center, a method of end milling of spiral bevel gear with disc milling cutter is put forward. According to the geometric characteristics of the tooth surface and cutter of spiral bevel gear, the relative position of the milling cutter and the machined tooth surface is adjusted to minimize the normal cross-section relative normal curvature between the tooth surface and the cutter envelope surface, and to increase the cutting bandwidth. At the same time, control the cutter axis vector to adjust the cutting depth to avoid machining interference. Finally, the tool position is transformed to the axis of NC machine tool, and the feasibility and correctness of the method are verified by VERICUT machining simulation.
