Using Contactless Scanning for Quality Control of Automotive Parts

Abstract:

The article presents the research of use of modern 3D measurement contact-less methods for quality inspection in automotive industry production. Experience with measuring parts and functional assemblies of complex shape and advantages of the optical methods of digitization are shown on a practical example of analysis of dimensional stability of car decorative strip plastic mouldings. The goal is to demonstrate that the modern methods of dimensional analysis of 3D products can significantly participate in optimization of the manufacturing process and ensuring higher quality of the products. Contact-less 3D systems, so called 3D scanners, were used for the measuring purposes. With their help, the tested sample were digitized in high resolution, and he obtained models of real parts underwent a thorough inspection of precision of shape and dimensions. The attention was directed primarily at the problematic spots – deviation of the strip ends when compared to the nominal CAD model. The analysis was performed using various alignment to the CAD model, thus contributing to finding context with respect to mounting points on the vehicle rails. Concurrently, an influence of galvanic plating on the accuracy of the product was studied.
