PROPELLER MANUFACTURE BY A NUMERICALLY CONTROLLED MILLING PROCESS,

Abstract

The report describes the process by which a torpedo propeller was produced on a numerically controlled milling machine. The process involved several steps. First, a geometric conversion routine translated the design data from conventional blueprint form to a set of rectangular coordinates. These converted data were expanded into a more complete array by means of interpolation routines. Then, through the use of the APT (Automatic Programmed Tools) computer system, programs were processed that converted the expanded data into the commands that actually machined the propeller. It is expected that propellers machined in this fashion will eventually be more accurate and less costly than conventionally produced propellers. (Author)
