Abstract

A flat metal plate is first formed into a suitable segment of a large generally spherical body. It is then properly positioned on a horizontal cradle and its edges cut vertically as if from infinity, i.e. so that they are all parallel. A cutter then traverses the pre-cut edge to form the proper contour for welding. The pre-cut edge itself forms an accurate fixed reference and cooperates with guides on the face of the curved plate to keep the axis of the milling cutter tool substantially perpendicular to the surface of the plate at the point of milling contact. When all segments are so made and then joined, the resultant generally spherical body will be within substantially closer tolerances.
