Abstract

According to the process, a blank is placed in a suitable jig flexed thereby to form a concave surface S, the degree of concavity of which corresponds to the degree of desired convexity. The surface S is then ground flat. When the jig is removed the blank resumes its unstressed condition since it is not flexed beyond its elastic limit, and the surface S assumes the desired degree of convexity.
