  • Real-time data collection apparatus for use in multi-axis measuring machine
    Patent number: 4724525
    Abstract: A real-time data collection apparatus for use in collecting data from a multi-axis measuring machine comprises laser interferometers for outputting position measurement data from the measuring machine axis. A measuring probe produces an output signal as a function of probe deflection. The measurement data from the laser interferometers and the probe data are simultaneously captured in response to a data capture signal. The simultaneously captured data is input to a data analysis computer for subsequent processing.
