ABSTRACT:
An apparatus for machining a compound curved surface upon a large plate-like metal workpiece comprising an elongated horizontal bed having parallel curved longitudinal edges, a table slidably mounted upon the bed, and having guide strips complementary to and engaging the edges for reciprocating the table horizontally along an arcuate path. A cross-bar is arranged transversely above the bed and table and a support plate having parallel curved edges is mounted upon the bar for slidably moving transversely of the bed. A slide member is mounted upon the support plate and has guide elements engaging the curved edges thereof for movement of the slide member relative to the support plate along an arc whose axis is longitudinal of the bed. A tool member carried by the slide member engages the workpiece, which is fastened to the table, for forming the curved surface thereon as the workpiece is reciprocated longitudinally of the bed, and the tool member is moved transversely of the bed.
