为了实现产品的快速设计和设计知识的重用,提出了基于可配置模板的方法。该方法的设计思想是从产品结构设计、零部件装配、安全校验到绘制出图的全流程都利用可配置模板实现。在考虑设计知识动态演化特性的前提下,建立了包括产品结构配置模板、参数校验模板、模型模板、二维工程图模板、计算报告模板和BOM表模板在内的可配置知识模板构建方法。最后给出了该方法在吊具产品配置设计过程中的实际应用,验证了该方法的可行性和有效性。 相似文献

Rapid tooling (RT) is the technology that adopts rapid prototyping (RP) techniques and applies them to tool and die making.
Research into RT techniques has shown that it is gaining more importance and is starting to pose a serious threat to conventional
machining. In this paper, several popular RT techniques are discussed and then classified. A comparison is also made on these
techniques based on tool life, tool development time and cost of tool development. 相似文献

Laminate tooling is a relatively fast and simple method of making large metal tools directly for various moulding processes in the rapid prototyping and manufacturing field. Metal sheets are usually cut, stacked, aligned and joined. In most cases, lasers are used only for the cutting of steel sheets in laminate tooling, but in this study, the use of the laser was expanded for improved laminate tooling. First, the laser was applied to eliminate the stair steps of steel laminates by filling them with molten filler metals. Then application of hard particles to molten filler metals for improved surface hardness of laminate tools was investigated. To achieve this goal, a CO2 laser system composed of a CO2 laser, a five-axis CNC table, an automatic feeding equipment of filler metal and flux and a personal computer was developed. Various experiments on filling stair steps and hardening were performed and the results were verified and estimated. 相似文献

Rapid prototyping (RP) is fast becoming a standard tool in today’s product design and manufacturing environment. Significant
benefits in terms of lead time and cost savings have been reported with the use of RP technology. However, these benefits
can be derived only during the design and planning stages of a new product where RP parts are produced in small quantities
for design evaluation, form fitting, and marketing analysis. The high cost of raw material stock used in current RP systems
makes them economically unsuitable even for small-batch production during the product evaluation and manufacturing stages.
Further to this, the difference between the mechanical and physical properties of RP and traditional manufacturing materials
limits the functionality of RP end products. Rapid tooling (RT) technology has opened up new cost-effective solutions for
small-batch production. In this paper, a technique using a rapid soft-tooling approach, namely, aluminium filled epoxy resin
tooling for injection mould preparation is successfully explored. An aluminium filled epoxy resin mould is evaluated and the
characteristics of the injection-moulded end products are presented. 相似文献
