Abstract:
ABSTRACT
Rolls-Royce Deutschland (RRD) is germans aeroengine manufacturer with the complete responsibility for design, manufacturing, validation and in-service support for engines.
Within component manufacturing beside complex machining operations a series of special processes such as controlled shot peening are applied. Benefit of improved process
control will be improved quality (less process failures) and reduced time and cost for process control. Standard control method for shot peening based actually on Almenstrip
peening and measure the bending of the strip as measure of the "Almen-Intensity" prior to the peen the part. Here a reduction of almenstrip peening will deliver benefits in
terms of lead time for components and will reduce the resource (e.g. machine capacity, operators) needed for process control work.
An optical measurement system has been modified for shot peening application delivering the distribution of the velocity for typically used peen media and manufacturing
equipment. It has been demonstrated that the system is feasible to determine peen intensities at least comparable to Almen tests.
