The conceptual design model for mechanical product and its computer aided design are the important and focus problems. A mechanical product design process of FPBS model, function-principle-behavior-structure model, was put forward and discussed. The semantic relationships between the elements of FPBS model were studied to make foundation for the application of FPBS model. The operational demand of knowledge system for FPBS model was analyzed, and indicates the ontology can be applied effectively to knowledge system operation of FPBS model. Then, an ontology based FPBS model was established and a FPBS ontology model system was constructed. The experimental results indicate the model can be used in computer aided conceptual design for mechanical product effectively.

In this paper, our aim is to design and built a lightweight single-piston floating caliper, without compromising the performance. The aim is to design a caliper as simple as possible so that the manufacturing cost would be low. Mounting position can also be varied in this design. To make the caliper lighter it is necessary to remove material, Aluminium 7075 is used as the material, and Asbestos is taken as the brake pad material. To maintain the stiffness the material has to be used in a more efficient way. A computer-aided design model of a brake caliper is created in Solidworks and analyzed for stress and deformation in ANSYS Workbench.

Rapid prototyping uses layered manufacturing technology to produce functional parts directly from 3D computer-aided design model without involving any tools and human intervention. Due to layer by layer deposition, volumetric error remains in the part which is basically the volumetric difference between computer-aided design model and the fabricated part. This volumetric error causes poor dimensional accuracy and surface finish, which has limited the widespread applications of rapid prototyping. Although rapid prototyping is able to produce functional parts in less build time with less material wastage, today many industries are looking for better surface quality associated with these parts. Literature discloses that the part quality can be improved by selecting proper build orientation that corresponds to minimum volumetric error. In support of this, current study presents a computer-aided design-based novel methodology to precisely measure the volumetric error in layered manufacturing process, in particular fused deposition modeling process. The proposed method accepts computer-aided design model of the part in .CAT format and automatically calculates volumetric error for different build orientations. An Excel function is integrated with it to determine optimum build orientation based on minimum volumetric error. Several simple and complex examples verified the robustness of our proposed methodology. We anticipate that the current invention will help future rapid prototyping users in producing high-quality products through an intelligent process planning.

The Impact

Today, product design process is facing a market globalisation led by distributed teams. The international market context, in which industrial companies evolve, leads design teams to work in a large multidisciplinary collaborative context using collaborative practices. In this context, product design process is driven by the integration and optimisation of stakeholders’ collaboration. Thus, to facilitate collaborative steps, new management strategies are defined and new information systems can be used. To this end, we have focused our article on the topic of collaborative product design project management. We have underlined the necessity to use quantitative and non-intrusive indicators during the management of collaborative design phases besides subjective evaluations. Tracking these indicators is performed in parallel to the existing approaches in order to evaluate the performance of collaborative design project. Moreover, these indicators can show the impact of the collaboration steps on the design project evolution. The computation of proposed indicators is based on precise metrics which details the completeness of the computer-aided design model and its evolution depending on the used collaborative tools and the project milestones. This computation uses the importance of each computer-aided design model part and the transformation rate of each part of the computer-aided design model.
