渐开线塑料齿轮模具线切割代码自动生成方法研究

为了提高塑料齿轮模具的开发速度,研究了新的渐开线齿廓拟合方法及其线切割代码自动生成方法,提出了等曲率半径变化法来确定拟合节点坐标和等弧长圆弧拟合法来精确拟合渐开线齿廓,并推导出了相应的计算方法。最后,利用VB语言开发出精确度可由用户自由控制的渐开线齿廓线切割代码自动生成器,为渐开线齿轮模具的精确快速开发提供帮助。

The Research of Method to Generate Automatically Wire Cutting Code of Involutes Plastic Gear Mold

In order to improve the speed of development of plastic gear mold, researching the new method of fitting involutes profile and the method to generate automatically wire cutting code. Putting forward the same change of curvature radius to find the coordinates of fitting nodes, deducing the corresponding calculation method. Finally, developing the automated producer of involutes profile cutting code through VB language whose accuracy can be controlled by users, providing assistance for the rapidly development of involutes gear mold.
