摘要：

基于对采油螺杆泵螺杆形状的分析建立了螺杆螺旋曲面方程;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，建立了基本的铣刀刀刃廓形方程。根据铣刀的实际使用情况，针对成形铣刀用钝重磨后产生的加工误差，进一步建立了具有合适前刀面和恒定后角的铣刀刀刃廓形方程。对廓形方程进行干涉检查，保证了铣刀廓形的正确性。该铣刀刀刃廓形方程为铣刀的设计制造奠定了理论基础,对实际生产具有重要意义。

Abstract:

Through analyzing the shape of screw of oil extraction progressing cavity pump,a spiral surface equation of the screw was established;and from the relative motion between formed milling cutter and screw,the basic profile equation of formed milling cutter was established with molding milling principles and coordinate transformation theory.According to the actual use of milling cutter,aimed at the causes of processing errors after wear of formed milling cutter,a complete profile equation of formed milling cutter was established which had proper rank and constant clearance angle.Through interference checking for profile equation of formed milling cutter,the correctness of profile equation was ensured.The profile equation provides a theoretical foundation for design and manufacture of the formed milling cutter,and it will have great significance to actual production.

Key words: screw, formed milling cutter, cutting edge, profile equation
