To eliminate flaptrack wall deflection during machining operations which can exert up to 3000 lb of force, the fixture incorporates an expandable T-bar that presses against the inner workpiece walls.
A major aerospace manufacturer needed machining flexibility to process a family of four sizes of aircraft wing flaptracks. The solution was a four-machine FMS that reduced overall cycle time by 200 hours.
The first was the desire to avoid distortion from heat processing, which led to the decision to machine the flaptracks after heat treating.
The solution was a modular fixturing system that accommodates the four sizes of flaptracks by modifying selected clamp elementss.
