ABSTRACT:
In a method and apparatus for forming a curved surface, a polishing plate consisting of a film-like elastic member is supported at two positions, i.e., central and peripheral portions thereof, and is rotated while two cylinders having different heights and diameters are urged upward against portions between the central and peripheral portions of the polishing plate, and an object to be processed is urged downward against a surface formed between the two cylinders while the object is rotated, thereby forming a curved surface.
