When machining large parts such as an aircraft bulkhead or wing rib, workholding can be a challenge. What's the best way to clamp a part when 95-percent of the material will be machined away? How should thermal expansion and vibration be dealt with? How can setup changes be reduced?
According to Michael Gaunce, group manager of stationary workholding at SCHUNK, aerospace milling applications can benefit from a better approach to workholding. How you clamp a part should be considered as early as the design phase. In many cases, adding retention points in a first OP can reduce setup changes and improve quality.
