如本刊79年第4期《拉刀刃磨新方法的调正计算》一文(以下简称《调正计算》)所述,新方法刃磨出的拉刀前刃面是球面的一部分——球带。该球面的球心为砂轮轴心线与拉刀轴心线的交点,如图1。图1所展示的既是新法刃磨时拉刀与砂轮的相对位置,也是《调正计算》中作为公式推导基础的几何关系图形。《调正计算》中介绍了计算方法,并且说也可画线图作为调正机床的依据。这确实比盲目调正好,但作为操作工人使用仍不方便,特别是当拉刀规格品种繁多,砂轮大小有变化时使用不方便。为解决这一问题,图1提供了极为有用的数学模型,模
As described in our article, No. 4 of 79, “A New Method for Adjusting the Broaching Sharpening Tool” (hereinafter referred to as “Tuning Calculation”), the new method of sharpening the broach rake face is part of the sphere - the ball band. The sphere of the spherical center of the grinding wheel axis and broach axis of intersection, shown in Figure 1. Figure 1 shows both the new law sharpening broach and the relative position of the wheel, but also “correction calculation” as the basis for the derivation of the formula geometry. “Adjustment calculation” describes the calculation method, and said that you can draw the line chart as a basis to adjust the machine. This is indeed better than blind adjustment, but it is still inconvenient to use as an operating worker, especially when the broach size is varied and the size of the grinding wheel is inconvenient. To solve this problem, Figure 1 provides a very useful mathematical model
