Abstract

This paper addresses the problem of 3D reconstruction and orientation of the cutting tool on a machine tool after it is loaded onto the spindle. Considering the reconstruction efficiency and that a cutting tool is a typical object of surface of revolution (SOR), a method based on a single calibrated view is presented, which only involves simple perspective projection relationship. First, the position and the orientation of the cutting tool is determined from an image. Then the silhouette of the cutting tool on the image is used to generate the 3D model, section by section. The designed algorithm is presented. This method is applicable to various kinds of cutting tools. Simulation and actual experiments on a machine tool verify that the method is correct with an accuracy of less than 1 mm.
