铲齿成形铣刀的计算机辅助设计

CAD of Relieving Form Cutters

介绍了在微机上开发的铲齿成形铣刀ＣＡＤ系统的构成、应用环境及各模块功能，推导了主偏角及工件廓形偏置后坐标点的计算公式，对铲磨干涉校验公式进行了补充说明，并给出了应用实例。

The built-up , applying environment and module functions of a CAD system developed in PC for designing relieving form cutters are introduced. The formulas for calculating κ r and coordinate points of the offset workpiece contour are deduced. The examination formula of relief grinding interference is replenished. An applying example of the CAD system is given.
