    Abstract: A method and apparatus are disclosed for using a numerically controlled turning machine to automatically cut a thread in response to programmed data defining certain thread cutting parameters. The programmed data defines an initial thread cutting pass and the final thread depth. The method and apparatus cause the cutting tool to make a number of iterative thread cutting passes relative to the rotating workpiece with successive passes being made at correspondingly smaller cutting depths. The threading cycle is terminated by two finish passes at a predetermined minimum depth of cut.
