Basic Research On Some Key Technologies In Rapid Manufacturing Fender Mold

Arc Deposition Manufacturing is one type of shape-creative and mass-creative parallel rapid manufacturing technology using arc as thermal resource,which includes Plasma Deposition Manufacturing and Pulsed MIG welding. This technology provides a low-cost rapid manufacturing of high-quality way. The convex and concave mold designing is very essential in the rapid manufacturing technology for fender mold. The technical analysis of the numerical simulation can be used to determine the rationality of die design, optimize the process parameters of the correction, thereby forming a better design of the mold. In order to meet the rapid prototyping manufacturing system, the model of convex and concave mold must be simplifies and the STL should be detected and repaired. Only in this way the system can form deposition trajectory, preparing for the follow-up processing. Therefore, this paper has researched on rapid fender mold manufacturing technology, to achieving volume and surface finish forming integrated manufacturing. Key elements include:1. Based on the rapid tooling manufacturing technology, this paper has analyzed the rapid tooling manufacturing technology at this stage, studied the key to rapid tooling studied the key to rapid tooling technology and the characteristics, provided theoretical guidance for arc deposition manufacturing system.2. This paper has introduced the basic knowledge of the rapid tooling manufacturing technology, analyzed the forming principle of Plasma Deposition Manufacturing and Pulsed MIG welding, and studied the structure, equipment, principles, and characteristics of the forming process of the rapid tooling manufacturing system.3. The major issues and factors of the forming simulation results were analyzed in-depth, the forming process simulation of the fender metal sheet was simulated, and the simulation processes and the fender forming simulation results were studies.4. The basic knowledge about the rapid fender mold manufacturing technology was studied in detail, the molder of fender mold was reconstructed and the STL files were repaired.5. To validate the utility of above research, a double-twist leave has been made by Hybrid Plasma Deposition & Milling. The results show that the fender forming tool path is in full compliance with the analog processing path and manufacturing process technology, and provide the foundation for follow-up fender mold manufacturing.
