Traditionally, in the automotive and aerospace industry, assembly jigs are large, custom, permanent structures that are costly to both design and build. Assembly jigs are usually one of the largest non-reoccurring costs at the start of a manufacturing project. Manufacturers are under increasing pressure to reduce non-reoccurring costs, reduce time to market of products, and improve the capacity and utilization of their tooling. The BoxJoint system is an arrangement of beams and joints, which together forms a framework. There are no welds between the connecting pieces in the system, instead the parts are fixed to each other with friction. Harcourt HBOX™ units are used to join standard beams to form the framework of the jig. The framework is set to a loose tolerance facilitating a quick assembly process and the use of standard low cost beams. The final accurate interface between the jig and the component is achieved through adjustable HFLAG™ and HSHIMBOX™ units. Throughout the jig build process, laser metrology is used to quickly measure and adjust the position of the jig beams, HSHIMBOXs, and HFLAGs.
