[0002] With the continuous progress of China's manufacturing industry, CNC machine tools are developing towards higher precision. As an essential part of CNC machine tools, the quality requirements for CNC cutting tools are also getting higher and higher. Therefore, it is necessary to conduct quality inspection on the cutting tools. Otherwise, broken or worn cutting tools will affect the processing quality and efficiency, resulting in poor processing or even scrap.
