Checking fixture design is a complicated task requiring a strong professional background and rich practical experience. In order to enhance design efficiency and quality, this paper proposes a computer-aided checking fixture design methodology. The key issues include a new minimal volume bounding box generation approach for workbench design, a multi-objective optimisation algorithm of locator layout for location design, a multi-surface extension and transition method for checking components design and a flexible part library system to reuse standard parts and to assemble them automatically. As an implementation of the system based on the key methods, Checking Fixture Design Wizard for automobile parts, a plug-in on CAD software, is developed. Finally, a car door checking fixture design is taken as a case study to verify its feasibility and practicability.
