Quality Inspection for Punching Parts Based on 3D Alignment

Researched on quality inspection of parts in the punching porcess,a new method based on 3D alignment of digital prototype workpieces is introduced here based on reversing engineering.Its basic principle is that the measured points cloud of punching parts aligns with the digital prototypes in related software,Furthemore the processing error of punching parts is analyzed and the results of data processing is shown in visualization.
