Quality assurance on BMW convertibles

Measuring Systems: TRITOP

Keywords: Process optimization in production line, Quality assurance in production, Validation of fitting dimensions, Calibration stability of assembly jigs, MCS, PCS

Mobile optical 3D coordinate measuring technology is used for quality assurance on the production line in the BMW Regensburg plant. For the assembly of roof modules for convertibles, optical measuring equipment is used in process planning for the machine capability study (MCS) even before the start of serial production. On the assembly line the photogrammetric system then enables flexible inspection to be carried out during manufacture. Thus trends and deviations in production can be detected at an early stage. As result of using optical metrology rework time is reduced and production costs are cut down significantly. Also Quality Management can be specifically improved by means of process capability studies.

Optical Digitizing by ATOS for Press Parts and Tools

Measuring Systems: ATOS, TRITOP

Keywords: Springback, trimming, milling, casting

During recent years, optical sensors like the ATOS system for digitizing sheet metal parts and tools have been more and more used in the industry. In the following you can see how the nominal/actual comparison of sheet metals is used in the automotive industry for analysis and inspection purposes and on various applications in tool manufacturing.

3D Digitizing in Tool and Moldmaking

Measuring Systems: ATOS, TRITOP

Keywords: Milling, Forms and casts, Try out analysis

In tool and mold making it is important to capture the actual contour of a part. The traditional method for the acquisition of measuring data is time-consuming and requires transporting the tool to the measuring setup. Powerful digitizing systems, based on the principle of fringe projection, are an integral part of industrial process and measuring chains and constitute a good alternative.

Quality control of a sheet metal part using digitizing and adequate inspection tools

Keywords: Springback, Trimming, Hole pattern, Edges

With ATOS feature lines, like border lines and holes, can be accurately defined and the data is included in the digitized 3D point cloud data. From this data, Quality Control software packages can derive fast individual data points, data defining geometrical elements and border lines as well as the form of the surface.
