Quality Assurance and Control of Steel Blade Production Using Full Non-Contact Frequency Response Analysis and 3D Laser Doppler Scanning Vibrometry System

Quality management is one of the crucial aspects of the Industry 4.0 concept of industrial production. The key matter is to limit the time for the quality system processes in the total production time. This paper presents the use of non-destructive, non-contact experimental modal analysis using the single or multipoint approach for measurement over the surface of the product. The example of such quality assurance measurements, with the use of a 3D Laser Doppler Vibrometry System, is a proposal of advanced instrumentation and data acquisition systems which is the perfect fit for Industry 4.0 factory quality management systems.
