Open publisher page 0 citations

Abstract

For rotational parts with irregular curve profile, in order to achieve its manual programming and machining, we need to segment the contour curve according to the change of curvature. Through the calculation, we can get the minimum arc to fit the segments, and calculate the circular endpoint coordinates and radius by using the drawing methods. Finally, we develop the NC program. By the analysis of the result, we find the method can simplify the programming and improve machining efficiency.
