加工螺距固定不变的螺旋面盘形刀具,其廓形宜用电子计算机根据给定的被加工零件横截面廓形进行计算,这时方程式中所选择的变量,它的极值应该是容易确定的,图1中的ψ角就是这样的变量,它表示零件螺旋槽的横截面廓形在该点法线N 的位置。本文介绍的盘形刀具廓形计算方法同现有的各种计算方法的一个根本区别就在于它能保证接触线方程有唯一的解,当成形铣刀和成形砂轮绕本身中心线旋转时,其切削刃形成回转体(本文称盘形刀具)的回转表面。确定该盘形刀具的参数就是设计计算要完成的基本课题,也就是成形铣刀和成形砂轮的法向廓形。如图2所示,在万能铣床加工时,零件的坐标系XYZ 和盘形刀具(砂轮、铣刀)的坐
Machining spiral constant helical surface disc cutter, its profile should be calculated using the computer based on the cross-sectional profile of the workpiece to be machined, then the equation selected variables, its extreme value should be easy to determine , The ψ angle in Fig. 1 is the variable that indicates the cross-sectional profile of the part helical groove at the normal to point N of the point. The fundamental difference between the disc cutter profile calculation method introduced in this paper and the existing calculation methods is that it can guarantee the unique solution of the contact line equation. When the forming cutter and the forming grinding wheel rotate about their own center line, The cutting edge forms the surface of revolution of a rotating body, referred to herein as a disc cutter. Determine the parameters of the disc tool design and calculation is to complete the basic issue, that is, the forming profile milling cutter and forming wheel profile. Shown in Figure 2, universal milling machine processing, the part of the coordinate system XYZ and disc-shaped tool (wheel, milling cutter) to sit
