[0002] A robotic arm is an industrial robot that is usually composed of a series of connected mechanical components that can simulate human arm movements and is used to perform various tasks, such as assembly, welding, and handling. Robotic arm parts are the various parts and components that make up the robotic arm, including but not limited to joints, actuators, sensors, connectors, drives, etc. These parts work together to enable the robotic arm to complete various complex movements and tasks. Precision machining of robotic arm parts refers to the use of high-precision machining technology and equipment to manufacture and process the parts of the robotic arm to ensure that their size, shape, and performance meet the design requirements. This machining process usually requires strict control of machining parameters and processes to achieve high precision and high quality of parts. When machining robotic arm parts, in order to ensure the stability and accuracy of the parts during the machining process, positioning mechanisms are usually used to position the robotic arm parts.
