模具渐开线齿形的电火花线切割加工

Machining of Involute Profile of Die on WEDM

电火花线切割加工模具或齿轮渐开线齿廓之前,需先作曲线拟合,以便计算线切割编程数据。文章给出高精度的渐开线齿廓线曲线二点拟合法以及电火花线切割加工模具齿形和内齿精度简易检测方法。该方法对各种模具和圆柱齿轮的渐开线齿形加工均适用。

In order to calculate wire cutting program data, the curve fitting is done before the involute profile of die or gear is processed by WEDM. The paper puts forward the Two Point Fitting Method for involute tooth -profile, the method of tooth - profile cutting by WEDM, as well as a simple and easy method for measuring the accuracy of inner teeth. The method is universally applicable to the process of tooth - profile of various dies and spur gears.
