Shape & Dimension Control
For first article inspection and quality control, the ATOS measuring data of digitized components can be directly compared with the original measured data or CAD master data. Such a full-surface nominal/actual comparison can be used to quickly determine whether defined tolerance limits have been maintained, or to control which areas of a component have been deformed. During tool try-out, the ATOS 3D digitizer delivers fast results on the actual geometry of a stamped part. This makes it possible to verify on the shop floor that the part will fit properly during assembly and that it complies with optical requirements. The ATOS system not only measures deviations between the stamped part and CAD parameters over the entire surface but also checks hole pattern, trim and spring-back for required tolerances using special algorithms with subpixel accuracy for precise inspection of cut edges.
Detection of Material Defects
A material's forming limits might be exceeded during the stamping process without this being immediately visible to the human eye. GOM's ARGUS strain measurement system checks for areas of the material that have been critically weakened, e.g. due to extreme material thickness reduction.
