Title

Error Analysis for Four-Axis Side Milling of Undevelopable Ruled Surfaces

Abstract

Based on the geometric features of the undevelopable ruled surface (URS) and conical and cylindrical milling cutters, this paper analyzes the interference errors which take place when a part with a URS is machined using 4-axis side milling. Formulas to calculate the interference errors are derived, and methods to reduce the errors are proposed. Experimentation on a turbine impeller whose blades are URS shows that the derived formulas and the proposed error-control methods are effective. Thus, the analysis provides a promising solution for the practical problem occurring in the machining of parts with URS.
