[0002] Turning machine tools are one of the basic equipment for mechanical processing. Early turning machine tools mainly relied on manual operation and mechanical transmission, and the processing accuracy and efficiency were relatively low. With the advancement of science and technology, especially the introduction of CNC technology, the performance of turning machine tools has been significantly improved. CNC lathes control the movement of machine tools through computer programs, realize the automation and precision of the processing process, and greatly improve the processing accuracy and production efficiency. In the process of mechanical processing, positioning accuracy is one of the key factors to ensure product quality. For turning machine tools, the positioning function is particularly important. It can not only ensure the accurate position of the workpiece during the processing, but also reduce the processing error caused by position deviation and improve the processing accuracy of the product. In addition, the positioning function can also realize the rapid clamping and positioning of the workpiece, shorten the processing cycle, and improve production efficiency.

[0003] Although existing machine tools have made great progress in processing technology, they still rely on manual operation of workers in the positioning process. This traditional method is not only time-consuming and labor-intensive, but may also limit the positioning accuracy due to human factors, thus affecting the overall processing quality and efficiency.
