Abstract:  
SHOT PEENING is a special process with free-flying spherical particles as tools. The work of the balls on the surface can therefore not be controlled as easily as in a machine tool. Accordingly, the digitisation of process and quality parameters for the requirements of Industry 4.0 is difficult to achieve. Generations of engineers have been working for more than 150 years to gain control of the flying shot peening balls and their effect on the surface. The goals of shot peening are, in particular, safe and reproducible processes in order to achieve reliable cold work effects and the introduction of residual compressive stresses that significantly increase the service life of components under dynamic loads. For the future, the simulation of shot peening processes is a promising approach to reduce development time, optimise processes, and save energy. In order to clarify the fundamental development steps of blasting and peening technology against the background of the three phases of industrialisation up to the present day, it is first worth taking a brief look at historical records.
