摘　　要：根据双螺杆泵螺杆螺旋面端面截形型线方程,利用成形铣削原理和坐标变换理论,从成形铣刀与螺杆工件的相对运动关系出发,建立基本的铣刀刀刃廓形方程。利用Matlab软件对设计刀具过程中的三角超越方程等非线性方程进行求解,得到铣刀回转面轴截形,然后以铣刀回转面轴截形为已知条件,反求螺杆螺旋面端截形,验证铣刀廓形求解方法的正确性。According to lines equation of transverse profile of twin-screw pump′s screw helicoids,from the relative kinematic relation between formed milling cutter and screw,the basic profile equation of formed milling cutter was established by molding milling principles and coordinate transformation theory.Using Matlab software to solve nonlinear equation,such as trigonometric functions in the process of designing the milling cutter,the axial section profile of the milling cutter revolution surface was obtained,and it was taken as known condition, used for reversing transverse profile of screw helicoids.So the validity of this solution method was verified.
