摘要
麻花钻前刀面的螺旋槽形状的不同,直接影响着主刃的切削性能和加工刀具的轴向轮廓,结合麻花钻特有的几何特性,推导了一般情况下的麻花钻端截面方程和铣刀轮廓方程,并借助LabVIEW的数学工具包编写了相应的程序,在Pro/E中进行实体验证与理论完全吻合,为麻花钻精确建模和加工刀具的轮廓设计提供了一种新的方法。
The shape differences of the spiral groove on the front blade of twist drill will directly affect the cutting performance of main edge and axial profile of machining tool.According to the unique geometric characteristics of twist drill,the equations of the end section of twist drill and milling cutter contour are derived in general case,and compiles the program by means of maths toolkit of LabVIEW.The entity verification carried out in Pro/E is identical to the theory,which provide a new method for precise modeling of twist drill and the design of profile of machining tool.
