Abstract
A precision bending apparatus is provided for precisely bending tubes. The precision bending apparatus includes a preprogrammed bender for placing a selected sequence of bends in the tube. The apparatus further includes a position sensing means for sensing the precise position of locations on the bent portion of the tube. A control means is in communication with both the position sensing means and the bender, and is operative to alter the program of the bender based on data sensed by the position sensing means.
