✦ Synopsis

A unique computer-basedmethod is presented of producing marine propellers of moderate size. The surfaces of the propeller are calculated from a table of offsets as an array of rectangular coordinate points and displayed on a graphics terminal where they can be examined and, if required, interactively modified. Ultimately a propeller, requiring only a minimum of hand finishing, is obtained using a numerically controlled milling operation.
