[0002] CNC lathes, also known as CNC turning machines, are outstanding representatives in the field of industrial manufacturing. Based on traditional lathes, they incorporate advanced automated control systems, endowing them with the ability of automatic processing, and becoming a processing equipment with both high efficiency and high precision. In the processing process of CNC lathes, a pre-programmed processing and forming program is indispensable, which ensures that the equipment can accurately and automatically process the parts to be machined.

[0003] However, in the operation process of CNC lathes, there is also an important link - the loading and unloading of parts. This step refers to accurately placing the parts to be machined on the lathe and safely removing the finished parts after processing. In the traditional working mode, this link usually relies on manual labor, which not only requires workers to have rich experience and skills, but also faces the problems of low work efficiency and potential safety risks, such as the equipment may accidentally injure workers.

[0004] With the continuous development of the manufacturing industry, optimizing the loading and unloading process of CNC lathes, improving production efficiency and ensuring worker safety have become important topics in the industry.
