This project, sponsored by the U. S. Air Force , was the first application of puter technology to control the operation of a milling machine.Standard NC machine greatly reduced the machining time required to produce a part or plete a production run of parts, but the overall operation was still timeconsuming. Tape had to be prepared for the part, editing the program would result in making a new tape, and tapes had to be rewound each time a part was pleted. With this in mind, the machine manufacturers added a puter to the existing NC machine, introducing the beginning of CNC.The addition of the puter greatly increased the flexibility of the machine tool. The parts program was now run from the puter’s memory instead of from a tape that had to be rewound . Any revisions or editing of the program could be done at the machine, and chang
