Granted: 1993-02-02
Abstract: ABSTRACT OF THE DISCLOSURE Microfinishing devices and processes for in-process gauging of  a microfinishing process of generally cylindrical workpieces.  A size control shoe is  used  with a  microfinishing  shoe such  that  the diameter  of  a generally cylindrical  workpiece can  be continually  monitored during  the microfinishing  process.   Once  a  predetermined  diameter or   workpiece geometry is achieved,  the machining  process can  be terminated.   Several embodiments of  size control  shoes are  disclosed which  are  particularly adapted for retrofit applications for existing microfinishing equipment.  A "masterless" microfinishing  machine is  also described  having arms  which engage the size control and microfinishing  shoes which follow the path  of the workpiece  during machining.   Since the  shoes must  be maintained  in engagement with the  workpiece after  a desired diameter  is achieved,  the pressure applied by the  microfinishing arms is relieved  until all of  the workpiece surfaces are machined.  Methods incorporating periodic  reversing of the direction  of rotation of  the workpiece relative  to the shoes  are also described  which  provide  enhanced material  removal  rate  and  high accuracy.
