A horizontally arranged workpiece supporting table is reciprocally mounted upon a support bed and guided for longitudinal movement, relative to the bed, along a vertically arranged, horizontally axised arc-like curve, beneath a forming tool mounted above the bed upon a slide member moved transversely of the bed along a transversely directed, vertically arranged, horizontally axised arc-like curve. The up and down movement of the workpiece, as the table reciprocates in its curved path beneath the tool, coupled with the up and down transverse movement of the tool forms a predetermined, large radius, compound curved surface upon a plate-like workpiece supported upon the table.
