Product Models 1 - 4GUP1301

Goal(s)

Digital representations are key elements contributing to the product development process. The associated software, mainly CAD software and technical data management systems, allow the manipulation of the product description. This module aims to train students in the use of these tools in order to improve their mastery in the design office, and to specify data quality in the extended enterprise.
This module aims to train students to use these tools in order to improve their control in the design office, and to specify the quality of data in the extended enterprise.to create and modify a partial description of a product being designed through common geometric representations (CAD) and technical data management tools.to identify the different categories of forms that a product can take during its development process.to understand the limits of current software descriptions and to evaluate their consequences on the product development process,to share information on a product through technical data management systems. (The configuration of TDMSs will not be covered in this module).Exchange information between design support software.Organise steps in the product development process from existing software and its constraints.

This module is spread over the two semesters with :

• standard elements of CAD tools and expert uses (CAM, SCAN, Kinematic Simulation) in the first semester
• advanced modelling plus technical data management in the second semester
