摘要
传统麻花钻锥面刃磨有4个参数,但在已知这些参数时并不能准确地确定主刃的形状及其后角。用球向量法建立前、后刀面的向量方程,求出两曲面的交线即主刃曲线,建立辅助平面与端平面向量方程,通过求解辅助平面分别与端平面和后刀面的交线,从而可求出主刃上任意点的后角。运用Matlab软件进一步分析定位斜角及其他参数对主刃曲线和后角的影响规律,为钻头圆锥刃磨法提供了一种精确的计算方法。
By tradition,twist drills have four parameters,but in the practical processing,we can＇ define other parameters with the four parameters.The paper set up the front side and back side of the aiguille with the method of global vectors to resolve the intersectant line of the two sides,just the main edge.At the same time,it set up an assistant side and a plane to solve the back angle of the main edge in any spot.It analyzes the rule of the parameters＇ influence with the method of matlab.It also supplies an accurate method for this conical drill.
