Abstract

1338202 Planing LA SALLE STEEL CO 10 Jan 1972 [12 Jan 1971] 998/72 Heading B3L A process of removing metal from the interior surface of elongate workpieces 10 having a hollow constant cross-section comprises the steps of advancing a shaving tool 12 through the workpiece, heating the metal to be removed to a temperature within the range of 250‹ F. to the hot working temperature for the metal, and maintaining the rate of advancement of the tool to cause the temperature of the metal being removed to be raised to a final temperature above the hot working temperature of the metal. The initial temperature of the metal can be achieved prior to metal removal or during metal removal. The final temperature is generally above 700‹ F. and preferably above 1,100‹ F. The rake angle of the shaving tool is within the range - 70‹ to +20‹, though preferably between -5 degrees and +5 degrees, whilst the clearance angle is within the range -15 degrees to + 15 degrees, though preferably between - 2 degrees and + 2 degrees. The external surface of the workpiece may be supported by a die during machining to prevent swelling. Further a tube expanding plug may be passed through the workpiece simultaneously with the shaving tool to iron or expand the shaved internal cross-section. The shaving tool may have an opening therethrough to permit the passage of metal being removed.
