快速原型制造及其基本原理 总被引:4,自引:0,他引:4
一、赋予制造业新生命力的快速原型技术 快速原型与制造技术是国外80年代后期发展起来的一种新技术。它涉及CAD/CAM技术、数据处理技术,CNC技术、测试传感技术、激光技术等多种机械、电子技术,材料技术和计算机软件技术,是各种高技术的综合应用。它与虚拟制造技术一起被称为未来产品创新的两大支柱技术。它对缩短产品开发周期,降低产品开发费用具有极其重要的意义,甚至有人祢快速原型与制造技术是继CNC技术后制造技术的又一次革命。 随着以信息技术为主导的现代科学技术的迅速发展,传统的制造技术正在发生极其深刻的重大转变,主要表现在产品生命周期缩短,用户需求多样化和交货期日益缩短成为竞争的三个主要因素。快速原型技术与其它制造技术集成后,在新产品开发的时间和费用上将节约10%~50%,它在产品设计和制造过程中的作用如图1所示。 相似文献

This paper presents a comprehensive set of theoretical investigations and industrial applications of computer-based rapid
manufacturing technology for high-integrity aerospace components. Two rapid manufacturing processes have been proposed by
integrating rapid prototyping, high-speed machining (HSM), reverse engineering and geometric computation theory. They have
been validated through trial manufacturing of a matrix of current aerospace components embracing critical design features
to be found across the aerospace industry. Applied to future development programmes, this research will provide aerospace
companies the benefits of significant decrease in product introduction lead-time, savings in non-recurring product introduction
costs and considerable reduction in manufacturing costs for “one off” and low volume service parts. The findings can also
be applied to rapid prototype development in other industries, such as automotive and military. 相似文献

To shorten the product development cycle time and reduce the cost at the same time, which is very critical for the survival
of those small and mid-sized one-of-a-kind production (SMOKP) companies, various computer communication, simulation and computer
aided engineering and management techniques have been widely used in these SMOKP companies. However, according to our study,
the applications of these advanced computer technologies in these SMOKP companies are lack of system integration and synergy,
which result in communication errors, reworks, duplications and hence a longer product development lead time and a higher
cost. To solve this problem, an inter/intranet based computer aided rapid product development system is presented in this
paper. This system consists of a number of inter/intranet based computer models or subsystems for supporting rapid development
of a one-of-a-kind product. It also employs a novel concurrent product development strategy called “prototype based incremental
product development strategy” and an integrated product data structure called “product production structure”. Some industrial
implementations of the proposed system, product development strategy and product data structure are also reported in the paper. 相似文献

Non-metallic rapid prototyping has been successfully applied in several industries, but a metal rapid prototype is required
for functional prototypes and tooling applications. A metal rapid prototype fabricated using selective laser cladding is presented
in this paper. Laser cladding is one type of laser surface treatment process. During this process, an alloy is fused onto
the surface of a substrate. Laser cladding devices, i.e. powder feeder, CNC workstation table, laser shutter, and shielding
gas controller, were integrated to make automatically any cladding profile possible. The metal prototype was then fabricated
layer by layer. This is called the selective laser cladding system (SLC). The fabrication of the metal rapid prototype using
SLC technology is described and the detailed design and construction of the SLC is presented in this paper. 相似文献
