Competition generated the requirement of quick decisions at engineering activities. As a consequence, application of advanced computer modeling in engineering design needs application of intelligent computer methods to assist human decision making. A powerful CAD/CAM system with a comprehensive range of sophisticated modeling tools for describing engineering objects and programming tools for creating modeling procedures constitutes an appropriate environment to accept intelligent methods. The only way of survival for companies producing mechanical products on the competitive edge seems application of advanced modeling together with intelligent decision making. Much modeling, problem solving, database handling, visualization and other methods are involved in a typical computer-based engineering process. This process recently relies upon an integrated set of modeling tools and an integrated product database. Involving intelligent computer methods is a great challenge in this field. This paper surveys advanced modeling from the point of view of application of intelligent methods. It is organized as follows. A characterization of state of the art in advanced engineering modeling reveals important issues to be discussed in this paper. Following this, worldwide network-based group work of engineers is discussed. Human computer interaction (HCI) and network communication methods as important aspects of computer-aided engineering are outlined. Then recent development results in modeling of mechanical systems with special emphasis on integrated modeling of mechanical products, especially well-engineered shapes, are introduced. Finally, virtual manufacturing as an area of involving intelligent methods in CAD/CAM technology is discussed.

The Cost

Abstract U.S. industry spends billions of dollars as a result of poor interoperability between computer-aided engineering software tools. While ongoing standards development efforts are attempting to address this problem in today’s tools, the more significant demand in next-generation tools will be for representations that allow information used or generated during various product development activities to feed forward and backward into others by way of direct electronic interchange. Although the next generation of tools has the potential for greatly increased benefits, there is also a potential for the cost of poor interoperability to multiply. The goal of this work is to develop representations of information that are unavailable in traditional CAD/CAM/CAE tools to support the exchange of product information in a distributed product development environment. This paper develops a vision of next-generation product development systems and provides a core representation for product development information on which future systems can be built.

Tree Method

The divergent tree method was adopted in this paper, and an illustrative example of tool storage design in the machining center was given to describe the divergent thinking in the conceptual design process of mechanical products. Firstly general divergent tree method was applied to get various schemes of storage, then the primary schemes were achieved by using the measure of known characteristics, finally the excellent degree appraisal approach was applied to find out the optimum one. In addition, an intelligent computer aided conceptual design system of tool storage based on the divergent tree method and excellent degree appraisal approach was demonstrated in this paper.

This paper presents a design methodology for the thermal design and packaging of hybrid electronic-mechanical products. In this work, tight integration between ECAD and MCAD was achieved through the use of a web-based tool used in managing the concurrent designs, called the Domain Unified CAD Environment (DUCADE). This work also reduced the amount of time required for thermal simulation by using a web-based Design of Experiment Testbed (DOET) to systematically determine effects of varying system parameters before full-scale computational fluid dynamics (CFD) thermal modeling was performed. The design process began by proper selection of material, manufacturing process and cooling methods, based on electrical and integrated circuit design. DUCADE was then set up to monitor couplings between the various domains. This was followed by computer-aided-design and computer-aided-engineering of the mechanical package. In computer-aided-engineering, DOET was first used to determine variables that had significant effect on the thermal system response. Detailed CFD thermal simulations were then carried out in FLOTHERM only focusing on variables that the DOET determined to have strong effect. Rapid prototypes were fabricated to refine the design before final production. Each step of the cycle was tested and demonstrated through a case study on the design of the Berkeley Emulation Engine (BEE) which involved multi-disciplinary electrical, mechanical, and thermal design.

Aided Design

Computer-aided design of assembly processes (Computer aided assembly planning, CAAP) of complex products is an important and urgent problem of state-of-the-art information technologies. Intensive research on CAAP has been underway since the 1980s. Meanwhile, specialized design systems were created to provide synthesis of assembly plans and product decompositions into assembly units. Such systems as ASPE, RAPID, XAP / 1, FLAPS, Archimedes, PRELEIDES, HAP, etc. can be given, as an example. These experimental developments did not get widespread use in industry, since they are based on the models of products with limited adequacy and require an expert’s active involvement in preparing initial information. The design tools for the state-of-the-art full-featured CAD/CAM systems (Siemens NX, Dassault CATIA and PTC Creo Elements / Pro), which are designed to provide CAAP, mainly take into account the geometric constraints that the design imposes on design solutions. These systems often synthesize technologically incorrect assembly sequences in which known technological heuristics are violated, for example orderliness in accuracy, consistency with the system of dimension chains, etc.An AssemBL software application package has been developed for a structured analysis of products and a synthesis of assembly plans and decompositions. The AssemBL uses a hyper-graph model of a product that correctly describes coherent and sequential assembly operations and processes. In terms of the hyper-graph model, an assembly operation is described as shrinkage of edge, an assembly plan is a sequence of shrinkages that converts a hyper-graph into the point, and a decomposition of product into assembly units is a hyper-graph partition into sub-graphs.The AssemBL solves the problem of minimizing the number of direct checks for geometric solvability when assembling complex products. This task is posed as a plus-sum two-person game of bicoloured brushing of an ordered set. In the paradigm of this model, the brushing operation is to check a certain structured fragment for solvability by collision detection methods. A rational brushing strategy minimizes the number of such checks.The package is integrated into the Siemens NX 10.0 computer-aided design system. This solution allowed us to combine specialized AssemBL tools with a developed toolkit of one of the most powerful and popular integrated CAD/CAM /CAE systems.
