| Abstract: | Virtual manufacturing (VM) is one of the research highlights both in science circles and enterprise circles at present. In this paper, on analyzing the forming process of the workpiece and the sources of machining error, Cutter Trajectory Representation (CT-Rep) is presented, which is available for characterizing the machining quality of workpiece in VM. According to the CT-Rep, the surface geometrical topological model of the workpiece after turning operation is established and applied in virtual machining and measuring cell being developed. |
