Computer-aided CMM modular fixture configuration design

In this paper, a software that is able to plan fixture configuration and assembly procedure for modular CMM measuring fixtures is described. By applying Set Theory, a fixture structure is considered as an assembly unit divided into several sub-assemblies and elements. Each sub-assembly is defined as a functional unit that includes one contacting element, one connecting element, and some other assembly elements. Using 'minimum fixture elements' and 'simple fixture configuration' criteria, an assembly algorithm is developed to design a suitable fixture configuration and assembly procedure. The system is implemented using VC++ in a Solidworks platform.
