ABSTRACT:
Methods of making an inspection fixture to assess the accuracy of a manufactured, bent tube or tube assembly are disclosed. Coordinates of end points, intersection points, and other points of interest of the bent tubular part are provided to a CAD system. The coordinates are connected by a centerline. The centerline is projected onto an X-Y plane and widened. The projected centerline is extruded in the Z direction. The resulting three-dimensional extrusion is unfolded to form a flat pattern for a tube run. The process is repeated until flat patterns for the parts of a tube fixture are created. The resulting flat patterns are provided to a computer-controlled laser cutting machine. The inspection fixture parts are cut by the laser cutting machine and bent to their final shape in accordance with bend angle information generated from the three-dimensional extrusion in the CAD system. The bent parts are assembled on a base plate and welded together to form the inspection fixture.
