[0002] After the CNC machine tool completes the workpiece cutting, it is necessary to measure the workpiece accuracy and then decide on the subsequent processing procedures. The measurement method for large CNC machine tool workpieces is usually to move the workpiece to a special detection platform for measurement. The repeated disassembly and movement of large workpieces is time-consuming and laborious. At the same time, there are secondary positioning errors, which affect the processing accuracy and work efficiency. Sometimes the measurement personnel can move the detection instrument to the machine tool working platform, adjust the instrument and then measure the workpiece. Although this method eliminates the work of disassembly and movement of the workpiece, the work of adjusting the detection instrument is relatively tedious and complicated. It takes a lot of time to adjust the detection instrument within a large scale range of the workpiece, and there are many human factors, which affect the measurement accuracy and are subject to many restrictions. Summary of the invention
