CNC machining positioning method based on high-precision case part

The invention relates to the technical field of numerical control, in particular to a CNC machining positioning method based on a high-precision case part. The method comprises the following steps: firstly, establishing sensors at specified positions in a CNC machining positioning device, and establishing a wireless communication device based on the sensors; operation pose data of the CNC machining positioning device are collected through the sensors, and the operation pose data are transmitted to the data processing center through the wireless communication device; actual operation pose data of a driving motor in the CNC machining positioning device are collected and transmitted to the controller; and actual operation pose data in the controller are transmitted to a data processing center, the operation pose of the CNC machining positioning device is optimized, a control instruction is given to the optimized operation pose, and CNC machining positioning is carried out. According to the machining positioning
