| Abstract: | A novel process for rapid and economical tooling manufacture combining rapid prototyping and precision plaster casting was studied. Through the example of manufacturing a mould for the rubber tire, the main process flow of rapid tooling manufacture was analyzed and the key techniques of the process were pointed out. The dimensional precision of the mould manufactured can reach CT3 or CT4 and the surface roughness can reach Ra0.8～3.2μm. The process can greatly shorten the tooling manufacturing cycle and lower the cost and is an up_and_coming rapid manufacturing technology for metal tooling. |
