本文介绍铲磨盘形齿轮铣刀时,计算砂轮截形的一种较精确的方法。——编者盘形砂轮与成型铣刀和指状铣刀铲背面的接触线是一条空间曲线。为使铣刀获得一定的齿形,应对砂轮的截形进行相应的计算。工厂所采用的计算方法不能保证所要求的砂轮截形(这点将在下面说明)。故通常需对砂轮截形进行修正。但是, This article describes a more accurate method of calculating the wheel truncation when scooping a disc gear cutter. - The contact line between the eddy wheel and the cutter and the back of the finger cutter is a spatial curve. In order to get a certain tooth milling cutter, the wheel should be truncated corresponding calculation. The method used by the factory does not guarantee the required truncation of the wheel (this point will be explained below). It is usually necessary to correct the wheel shape. but,
