Abstract

A retrofit auto-indexing system for a turret punch press is described in which a predetermined location is provided to which both the upper and lower turrets of a non-indexing turret punch press are rotated. Upper and lower punching tools are mounted respectively in the upper and lower turrets in such a manner so as to be rotated simultaneously, using a single servomotor, to a desired angle. The auto-indexing system is controlled using a microcomputer which is connected to receive the numerical control programmed data, determine whether the code it is receiving relates to the auto-indexing function and, when it does, institute the instructed auto-indexing function. Otherwise, the microcomputer passes the numerical control programmed data directly to a minicomputer which operates the turret punch press in a known manner.
