标准齿轮盘铣刀齿形过渡曲线的研究

Study on the Transition Curve of Tooth Profile of Standard Disk Type Gear milling Cutter

标准齿轮企铣刀齿形曲线上渐开线部分各点的坐标可从有关资料中查出，而过渡直线及齿底圆弧部分则查不到，这给铣刀的设计和制造带来不便。本文通过分析计算补充了过渡直线及齿底圆派圆心的坐标，以及圆弧与渐开线切点的坐标等十分有用的数据。

The coordinates of the involute parts of tooth profile of standard disk type grar Anlling cutters can be found in relevant references. But there is none of such data for the transition straight line and tooth bottom arc parts. Ths causes inconvenience for the design and machining of drilling cutters. By analysis and calculation, the coordinate data for tooth were found, thus rnakis design and rnachining more convenient.
