A process for forming a metallic article such as a fluid actuated ram assembly and particularly a hydraulically actuated ram assembly which includes as an initial step production of a raw casting from a mold. Subsequently one or more transverse parting operations are effected to the casting so as to form components of the article which may subsequently be attached to form the article. Suitably the raw casting is mounted on a lathe for various machining operations to be effected prior to carrying out the parting operations.
