What considerations are most important when selecting a fixture for machining a thin-walled workpiece to minimize distortion?

When selecting a fixture for machining a thin-walled workpiece to minimize distortion, several key considerations are paramount. First, minimize clamping pressure. Thin-walled parts are easily deformed by excessive clamping forces. Use clamps that distribute force over a large area, such as soft-jaw clamps or contoured supports, to avoid localized pressure points. Secondly, provide adequate support. The fixture should support the workpiece as close as possible to the machining area to prevent v....
