Research on Calculation Method of the Cutter Setting Angle in Screw Surface Form Milling

Article Preview

Abstract:

The transition surface and the over-cutting phenomenon always appear in the screw surface form milling process which is based on the non instantaneous center envelope method. To solve this problem, an accurate calculation method of the cutter setting angle is proposed. The contact equation between cutter and workpiece is introduced. Spatial mathematical model is established according to the cutting tool profile calculation principle and the cutting mechanism. This method improves machining precision effectively, and can get the required screw surface. It also provides essential references for the design of form milling cutter.
