Transverse grinding outer circumferential surface roughness determining methodMethod for determining surface roughness of outer circumference of transverse mill

Abstract

The invention discloses a method for determining the surface roughness of the outer circumference of a transverse mill. A three-dimensional modeling method is used for determining the surface roughness of the outer circumference ground by a transverse grinding method; the method comprises the following main steps: firstly, establishing a grinding three-dimensional model; on the basis of the model,intermittently rotating the three-dimensional model of the grinding wheel for one circle around the central axis of the workpiece; wherein the rotation angle is alpha 2, Boolean operation is performed once every time the workpiece rotates, the last remaining part of the workpiece is called as a circumferential surface roughness calculation three-dimensional model by subtracting the grinding wheelfrom the workpiece, the inner contour line of the rough surface of the outer circle and the outer contour line of the rough surface of the outer circle are drawn, and the distance between the two contour lines is the circumferential surface roughness Ra of the outer circle.
