Paper Title:
Machining Theory of Forming Complex Inner Helicoid and Numerical Algorithm to Design Contour of the Disc-Mill Cuter
  Abstract

The inner helicoid of the PDM’s stator is a kind of typical inner surface that is complex and tenuous. This paper studies the theory to form the inner helicoid in the screw stator which has a large lead and whose cross-section is composed by convex and concave curves using disc milling method. According to the varieties of the curve types of workpiece’s cross-section, a numerical method was proposed to calculate the theoretical contour shape of the disc milling cutter using coordinates of the fewer points on the workpiece’s cross-section. The manufacturing test confirmed the correctness of the design algorithm of the cutter’s profile and feasibility of this milling forming method.
