【摘要】 简述了大型复杂螺旋曲面成形铣削刀具设计的基本原理和方法。提出了复杂螺旋曲面的工件计算直径dm、工件计算螺旋角βm、刀具安装角中心距α等工艺参数的选择方法，并给出了橡胶定子压胶心轴盘形铣刀廓形设计的应用实例。这一工艺参数确定方法解决了生产实践中的干涉、过切、畸变和失真等问题，能有效地提高产品的制造质量，有助于成形铣削技术的进一步成熟和完善。指出我国在对现有成形铣削机床进行经济性开环局部数控改造的同时，应尽量加快向半闭环成套数控技术转变和发展的步伐，以全面提高生产效率和产品质量。更多还原

【Abstract】 Special forming milling techique of large-scale complex spiral curved surface is described. The movement relationship between rotary milling cutter and workpiece is analuzed. A new method is advanced to optimize the primary technological parameters such as real calculated diameter dm, calculated spiral angle βm, tool setting-up angle and tool assembly central distance a. This method is put into practical production and shows entirely effective to solve the problems such as interference, excessive cutting-in, distortion or deformation of traditional technique.更多还原
