Abstract

1440711 Shaping superplastic alloy sheet ISC ALLOYS Ltd 12 Feb 1975 [5 March 1974] 9868/74 Heading B3Q An article is made of superplastic alloy sheet by shaping the sheet to form a projecting area using differential fluid pressure when the sheet has been rendered superplastic, and using a saw to cut an aperture in or trim an edge on the shaped sheet by removing the projecting area. Cutting and trimming operations are performed by a rotary saw the blade of which may be parallel to the general plane of the sheet or at an angle thereto. An aperture 5, Fig. 1, is cut by the saw 4 through the side wall 3 of a projection 2 formed to the required size. The resulting lip 6 may be bent flat or removed by machining. Projecting side areas may be cut away to form arches, or the flanged edge may be trimmed, Figs. 2 and 3 (not shown).
