Coordinate Measuring Machine Data Collector

Before the actual machining processes begin on certain steam turbine components, the coordinates of many points on the workpiece are collected and formated and used as data in a large computer program which controls machining parameters. The collection and formating of the input data are accomplished with a dual axis, six digit, Ferrand position readout and a three digit event counter each of which has auxiliary BCD outputs. The BCD outputs are connected to a Control Logic " L" Series Microcomputer. The microcomputer scans the BCD output from the Ferrand readout and the event counter, converts these data to even parity ASCII Code, properly formats the data and sends the results to an ASR-33 Teletypewriter. The tape generated on the Teletype is then used as input data by the machining parameters program mentioned earlier,
