ABSTRACT
Kugelstrahlzentrum Aachen GmbH (KSA), a company specialized in shot peening services and automation solutions, and Rolls-Royce Deutschland (RRD), a subsidiary of Rolls-Royce plc, are currently working together to develop and test an improved process control system for shot peening applications. The common goal is a system for monitoring peening intensities on-line in order to reduce Almen tests and consequently to cut process times and costs.
In the context of this joint project, KSA has down-scaled its shot velocity measurement system to measure smaller shot sizes down to 0.1 mm. The ISIC-system (Integral Shot Intensity Control) is able to detect shot velocities of ferrous and non-ferrous peening media as well as mixtures of different media sizes. The main results are at present: A clear linear correlation with Almen intensities, even higher sensitivity and an ability to quantify the influence of varying shot sizes and particle distribution.
