Concurrent versioning principles for collaboration: towards PLM for hardware and software data management

The change management (CM) and version control mechanisms used in the mechanical and software domains are presented in the product lifecycle management (PLM) and application lifecycle management (ALM) approaches, respectively. Based on their comparison, this paper discusses branching/merging concepts and utilises them to propose an evolution of the product data management (PDM) functions of PLM, thereby allowing PLM to become a collaborative platform common to software and hardware engineers. This evolution is an opportunity to develop a three-way merge tool for CAD documents. Recent works on model-merging techniques from the software development domain are evaluated in the process.

PHENIX: product history-based reverse engineering

Reverse engineering (RE) is an activity which consists in digitising a real part in order to create a CAD model. Today, a lot of references are centred on geometrical approaches based on transformations of the point cloud. The issued CAD models are generally ‘frozen’ or barely re-usable. Nevertheless, to support engineering changes in a new design process, the product should be represented with a parametric geometry. This paper suggests a knowledge-based approach in order to provide a product’s parametric CAD model. A data model based on the extension of the core product model (CPM) is suggested and enables to manage multi-CAD models of the knowledge-based RE process.

Simulations of consecutive diffusion process

Process simulation based on virtual reality can comprehensively present the real process on the computer. It can play an important role in the development and manufacturing field of diffusion furnace. This paper researches the establishment of consecutive diffusion process and the key techniques of process simulation. In the process of creating process simulation, V code would be created to control motion of each part. A simulation that reflects on the real process could be acquired with this research. This process simulation not only shortens the development time of diffusion furnace, but also makes designer have a perspective to the defects of product in the design process. It promotes the effective of design, and reduces changes in later period of design.

Intelligent modeling of moulded case circuit breaker
