Abstract


The past 20 years , the manufacturing market environment has undergone a major change , diversifying user needs and personalization . Therefore , the manufacturing sector continue to explore the production model of rapid response to market and technology strategy . DPST (Direct Prototype Spray Tooling) technology developed by Huazhong University of Science and Technology , the combination of robot and spray molding technology , rapid manufacturing injection molds and sheet metal with excellent wear resistance to corrosion of stainless steel , wear-resistant alloy surface stamping die advantage of the extra attention . In the DPST technology , spraying ceramic prototype is the use of industrial robots directly milling ceramic blank technology . But the ceramic material due to the hard and brittle characteristics , workability, and is much more than the metallic material difficult , therefore, now widely used mainly grinding processing method , the removal mechanism is cut in the vicinity of the tool edge material brittle fracture rather than like metal material generated as shear slip deformation . Ceramic brittleness , processing parameters , the robot running speed is not too large , resulting in long processing cycle . So how to ensure rapid processing spraying ceramic prototype is one of the key technologies of the DPST with high dimensional accuracy and surface quality ceramic archetypes premise . Therefore, this paper prototype technology for industrial robot machining . Clay has good plasticity, and the processing parameters , the robot running speed compared to the ceramic processing large increase , excellent molding characteristics . This article is an example of robot prototype manufacturing technology basic research to the clay prototype with ceramic prototype . The paper is based on a six-axis robot robot digital prototyping processing system . Forming characteristics of the prototype materials , design principles of a prototype tool path . Robot prototype machining path planning , using the indirect method to generate the machining path , and further research robot the clay prototypes with ceramic prototype of the processing . Finally, the automotive panel die , for example , using the indirect method to generate the a prototype machining path , robotic machining experiments successfully obtained a of ceramic prototype and clay prototype . Clay prototype accuracy and surface quality to meet the requirements of the subsequent finishing .
