Numerically controlled apparatus including functions of synchronous-simultaneous transaction and independent-simultaneous translation

Claim 1

A numerical control apparatus for simultaneously performing plural control operations comprising: an input unit (2) for receiving numerical control data from a source (1) thereof; a central processing unit (CPU) (3); a memory unit (4), said memory unit including a first memory region (41) for storing X, Y and Z translation-axis data, a second memory region (43) for storing distance data for each translation axis, a third memory region (421) for storing synchronous-translation velocity data for each translation axis, a fourth memory region (422) for storing independent-translation velocity data for each translation axis, and a fifth memory region (440) for storing independent-translation axis data; and means controlled by said CPU for processing data received from said source and storing each type of said data in respective memory unit regions and, upon command, selectively reading said stored data from said memory unit in accordance with said command, performing calculations to derive numerical control signals therefrom in the form of a plurality of incremental control signals representing control operations, and applying said control signals to control means for performing said control operations; said control operations including each of a control operation such as linear translation wherein a single translation in an axis is performed, independent translation wherein translations of plural means are performed in different axes independently at the same time, synchronous translation wherein translations of a plurality of means are performed simultaneously in a plurality of axes, synchronous translation wherein translation of a single means is performed in a vectorial direction, and combinations of more than one of said translations simultaneously.
