This paper describes Lockheed's system for tracking the raw material and flight hardware traceability, inspection, and manufacturing records of the heat-resistant tiles used to ensure safe re-entry of man-rated space vehicles.
An IBM (MB-09) Card was keypunched with the hardware part number, serial number, forty-one measurements, and Material Review Dispositions on reject conditions. (This system is currently being modified to accommodate the use of bar codes, which permit more Material Review Disposition data to be included than do punched cards.) Stations for data input and retrieval located throughout the processing facility allowed manufacturing, inspection and traceability workers to make hardware process inputs via the cards, card reader, and CRT. Statistical Process Controls are used at key points to enable adjustment of processes to specification values.
This paperless data input and retrieval system significantly improved performance by reducing input errors and improving the readability of raw material and flight hardware traceability, inspection, and manufacturing records over hand-written entries.
