  • Selectively grouped axes linear interpolation numerical control system
    Patent number: 5146410
    Abstract: A computerized numerical control system controls the axes of a computerized numerical control apparatus (20) from a programmable machine controller (10) coupled to the computerized numerical control apparatus (20). Command values for the axes, information with respect to the grouping of the axes, and execution times for the axes in respective groups are sent from the programmable machine controller (10) to the computerized numerical control apparatus (20). When all commands for the axes in the respective groups are received by the computerized numerical control apparatus (20), pulses start to be distributed to the axes, and the pulses are distributed within the execution times. Linear interpolation can be performed on any desired combination of axes of the computerized numerical control apparatus (20) for preventing physical interference which could otherwise occur between axes when an automatic tool changing (ATC) mode is controlled by the programmable machine controller (10).
