A story in the November 1980 issue discussed cost-efficient production of numerical control (NC) part-programs. Aerospace structural components maker Monitor-Boxart of Farmingdale, N.Y., was about to complete a technology overhaul, converting its primary part-program-input medium from computer tape to "flexible diskettes." The program, which began in 1970, included installing a mini-computer-based turnkey system. It expected the benefits to include the creation of an in-house computer facility and elimination of machine downtime due to tap breakage.
