Abstract
A residual height trajectory algorithm of complex surface plane envelope is proposed for NC grinding of complex surface. Firstly, based on the differential geometric relationship between the grinding wheel end plane and the workpiece surface, the properties of the plane enveloping surface are analyzed; secondly, the residual height based on the space vector is calculated; Secondly, the algorithm is proposed by using the tangent characteristics of the contour line of the equal residual height; Finally, the tool path of the ellipsoid convex surface is calculated, and the characteristics of the two different tool paths are compared and analyzed, and it is proved that the proposed method is effective The tool path has higher machining efficiency at the residual height.
