Automotive sheet metal parts must be stamped to exact dimensions for a vehicle to assemble properly. A radius stamped into the part and the location of the radius relative the part's edge, called the flange, must be precise for fit-up and aesthetic reasons.
Small inside radii are almost impossible to measure with mechanical radius gages. An inspector cannot always see the fit of the template gage against the sheet metal because of the design of the part. Measuring the length of the flange is equally difficult since the inspector cannot repeatably find the exact point that marks where the radius ends and the flange begins.
Also, over time, bending sheet metal thousands of times over jigs, presses or molds can wear down the sharpness of the edges, resulting in parts outside acceptable tolerances. Inspect the inside and outside radius of the bends and press edges for consistency of fit during assembly and get notifications when edges no longer meet requirements. For radius measurements, the TS800 comes with the proper radius standoff but is a separate accessory for the HS702 or HS703.
