ABSTRACT:
A numerical control system for lathes includes a controller adapted to calculate a tool moving amount based on data from a tool moving mode-punched tape as read by a tape reader for each sampling time .DELTA.t when a pulse is generated from a sampling pulse generator and on spindle rotation position data detected by a spindle position detector, and executes a tool action instruction mode including a feed per minute instruction mode, feed per spindle revolution instruction mode and thread cutting instruction mode by operating a tool through a servo system in accordance with the tool action mode.
