【Abstract】 According to the design of an agricultural irrigation emitter mould ,the paper introduced the process that uses Pro/ENGINEER technique and advanced RP,RT techniques to manufacture mould. The applications of Pro/ENGINEER and RP, RT techniques make the mould design, production and modification faster and more easily. Realization of the 3-D display on screen by the Pro/ENGINEER software reduces the iterative process in research of product and accelerates the exploitation of new product. Primacy product manufactured with RP technique can avoid disagreement between the model and product and accelerate the design and manufacturing of mould. RT technique can rapidly manufacture the mould and develops benefit of RP. In the paper, an efficient method was brought forward to the key point and problem brought with the application of high and new techniques.更多还原
