机器制造业广泛使用盘形刀具加工零件的螺旋面。实践中常用作图法或作图解析法确定刀具截形,这种方法很直观,可以弄清根据原始设计参数能否加工出需要的零件表面、是否存在过渡曲线、过渡曲线的尺寸以及刀具的结构尺寸等等。现在采用的作图法的基础是作出一系列垂直于刀具轴线的平面与零件螺旋面的交线。每作这样一条交线,工作量都很大,而且截面形状随着平面沿刀具轴向的位移而变化,这就使作图十分繁琐。如果不是取垂直于刀具轴线的平面,而是取垂直于零件轴线的平面,则作图
The machine tool industry makes extensive use of the helical surfaces of disc-shaped tools for machining parts. In practice, it is often used to determine the tool truncation in the drawing method or the drawing analysis method. This method is very intuitive and can clarify whether the required surface of the part can be worked out according to the original design parameters, whether there is a transition curve, the size of the transition curve, Structure size and so on. The drawing method now used is based on making a series of intersections between the plane perpendicular to the tool axis and the helix of the part. For each such a line of intersection, the workload is great, and the cross-sectional shape with the plane along the tool axial displacement, which makes the mapping is very complicated. If it is not to take the plane perpendicular to the tool axis, but to take the plane perpendicular to the axis of the part, the mapping
