[0002] In the process of mechanical processing, the surface of the workpiece needs to be punched, especially the blind hole processing. Since the blind hole is a conductive hole that connects the surface layer and the inner layer but does not penetrate the entire board, it is not easy to grasp the size during the processing. Therefore, it is necessary to measure it before processing, and then accurately process it after the measurement and marking are completed.

However, due to the wide use of workpieces, the external shapes are not uniform, and some have curved surfaces, which cannot be effectively measured with a vernier caliper, thus affecting the accuracy of workpiece drilling. In addition, the workpiece cannot be fixed during measurement, resulting in errors in the measurement of the workpiece, resulting in unqualified products during the processing process, increased production costs, and the inability to effectively guarantee product quality.
