摘　　要：快速成型技术是集计算机辅助设计、数控技术、精密机械、电子技术、激光技术,以及材料科学于一体的跨多学科领域的新型制造技术。在农机零部件的开发制造过程中,快速成型技术能够结合农机零部件铸型尺寸大、结构复杂的特点,通过铸件三维模型剖分、分块加工、坎合组装浇注等工艺技术,快速完成单件、小批量新产品的试制。在制造过程中,利用无模数字化快速成型机及激光烧结机,可加工出任意复杂形状的铸型,大幅缩短复杂铸件的开发周期,对促进企业产品创新、降低新产品研发成本、提高产品竞争力具有重大意义。Rapid prototyping technology is a new manufacturing technology across multiple disciplines and collecting computer-aided design, numerical control technology, precision machinery, electronics technology, laser technology and materials science. In the development and production process of agricultural parts, rapid prototyping technology can be combined with large casting size and complex structure characteristic of agricultural machinery parts. Through three-dimensional model subdivision, block processing, re-assembly casting and other technology, a single piece, small batch trial can be rapidly completed. In manufacturing process, any complex shape models can be made through digital processing and mold sintering. It has great significance in promoting product innovation, reducing new product development costs and improving the competitiveness of products.
