摘　　要：成形磨削与车削相比可显著提高蜗杆的齿形精度和表面质量。根据螺旋面形成原理建立了渐开线蜗杆的齿面方程,利用空间啮合理论计算出了磨削蜗杆所需砂轮的轴向截形,依据此截形数据设计了砂轮数控修整方案,并用修整好的砂轮磨削工件实现蜗杆的数控成形磨削加工。Forming grinding can be used to improve the profile accuracy and surface quality about the worm significantly com- pared with the machine turnery. Based on the formation of helicoidal surface, a tooth surface equation is deduced. The spacial meshing theory is used to calculate the axial section of the grinding wheel. With the result to design the routes of dressing, then the finished grinding wheel is used to grind the worm to realize the CNC form grinding of the involute worms.
