We provide the control system for shotpeen machines manufactured by Straaltechniek B.V. These machines are used by aircraft engine manufactures such as Rolls Royce to shotpeen their turbine components.
Shotpeening is the process of plastically deforming the outer surface of a component by shooting hardened balls onto the surface. The purpose is to introduce compressive stresses in the material which decrease the possibility of fatigue cracks developing, thus increasing lifespan and reliability of the component.
The result is dependent on a number of variables such as size, density, speed and angle of the balls, the material properties and duration of the shotpeen process. ‘Overpeening’ happens when the material is peened longer than necessary. This not only costs time and money but can even increases the likelihood of fatigue cracks and must be prevented.
Better insight in the peening process would allow for optimization of the process variables resulting in better quality and save considerable amounts of time and money..
- Research literature on the prior work done on simulating the peening process.
- Is it possible to predict coverage based on the known process variables?
- Is it possible to optimize the process parameters such that 100% overall coverage is reached in a minimum amount of time?
