A new technique for flexible sheet metal forming in small batches was proposed. To realize the formation process, a forming machine was designed and manufactured. The forming machine is numerically controlled by computer. A sheet metal blank is formed locally by the set of rigid or elastic standard tools, and the local forming operation is repeated incrementally while the sheet metal is transferred regularly. As a result, the blank can be formed into various shapes. Forming processes for spheric, elliptic and hyperbolic shapes were examined. It has been confirmed that products of various fundamental shapes are successfully formed with good geometric accuracy and surface roughness, by adjusting different sequences of incremental forming and several forming parameters.
