Abstract: 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.
