Introduction: The shot peening process is managed by various conditions such as injection pressure, injection amount, particle diameter of injected material, injection distance, etc. It is essential for the shot peening process to manage quality by managing these conditions and actual injection such as arc height, intensity and coverage. However, it is impossible to measure the arc height and other properties even if the injection conditions can be managed constantly by monitoring during blasting of the actual product. Therefore, since total inspection after shot peening is virtually impossible, it is necessary to periodically extract products and test them outside of processing. When an abnormality is found in the inspection process, it is necessary to remove a set of products in a batch amount, and the loss is large. Also, it is necessary to arrange for personnel to conduct inspection outside of processing. Furthermore, when changing after the process changeover of products, initial product inspection is necessary, and the fact that production cannot be done until results are obtained is a problem. In addition, due to diversifying needs and shortening of the product life cycle in recent years, the introduction of cell production methods in various industries is advancing. The cell production method described in this paper refers to a flexible production line aimed at achieving multivariate variable production for small-lot mass production through the conveyor production method using conventional conveyors. As the demand for multiple types of products increases, problems such as an increase in process changeover work and a decrease in production lead time cannot be disregarded. At this time, we will propose a peening management system in hopes of providing an opportunity to solve those problems.
