针对级进模的结构特点,在分析镶拼凹模结构的基础上,采用自动化和交互式相结合的设计方法,实现了级进模镶拼凹模的分割设计,同时还提供了分割点和分割线的交互修改功能。采用基于图形的几何约束求解方法,对级进模镶拼凹模进行参数化设计,当镶拼块外形尺寸发生变化时,分割线可随镶拼块外形尺寸变化而自动变化,简化了设计修改过程,提高了设计效率。 相似文献

The design of machining fixtures is a highly complex process that relies on designer experience and his/her implicit knowledge to achieve a good design. In order to facilitate its automation by the development of a knowledge-based application, the explicit definition of the fixture design process and the knowledge involved is a prior and a fundamental task to undertake. Additionally, a fundamental and well-known engineering principle should be considered: the functional requirements and their associated constraints should be the first input to any design process. Considering these two main ideas, this paper presents the development undertaken to facilitate the automation of the fixture design process based on a functional approach.In this context, the MOKA methodology has been used to elicit fixtures knowledge. IDEF0 and UML have been used to represent the fixture design process. A methodology based on the function concept and aiming to formalize such design process is proposed. Fixture functional requirements have been defined and formalized. Functional fixtures elements have been used to create a functional design solution, the link of these elements with the functional requirements and with typical commercial fixture components has been defined via tables and rules mapping. And finally, a prototype knowledge-based application has been developed in order to make an initial validation of the proposed methodology. 相似文献

AbstractThe design and use of a novel temperature–time–gap width (TETIG) test specimen to characterise brazing alloys is described. The assembly was constructed from longitudinally sectioned bar(s) of the parent material(s), with outer segments of the two halves providing datum surfaces for the selfgapping system, conveniently bound in place with wire. Gap filling took place from alloy reservoirs in two machined grooves and flow could be chosen to take place from one or both, in a horizontal or vertical plane. Brazing alloys in the form of wire, sheet, paste, or powder can be used. The design overcomes a problem associated with conventional TETIG specimen design in which the effects of the flow distance of the molten filler metal are indistinguishable from the effects owing to the gap width of the joint. To investigate the reproducibility of the design, a Cu–Sn–Ni–Si–Ag alloy in both powder and solid forms was investigated in identical steel assemblies. Results which led to the use of the specimen design in the development and assessment of an improved alloy composition are reported. 相似文献
