Abstract

Abstract A tool-operating copy of a magnetic tape program for a machine tool is made from a master tape that has been produced by a large-scale computer. The master tape is scanned and a desired program therefrom is read into the memory of a small interfacing computer. The output of the interfacing computer is used to reproduce the selected program in a cartridge tape unit which provides the actual tool-operating copy. While the copy is being made, information temporarily stored in the interfacing computer is printed out for visual identification. Portions of the program determined to be in error by visual insepction, or portions desired to be changed, are fed back into the interfacing computer through a keyboard device to correct the appropriate parts of the program contained within the interfacing computer memory and also correct the cartridge operating copy.
