Abstract
Accurate and reliable techniques for providing a shot peening process kit used for mass production of thin walled aluminum components.
Claims18
A method for creating a shot peening process test kit, comprising:
- (a) determining a time dependent variation of a shot peening machine;
- (b) determining a machine to machine variation between a plurality of shot peening machines;
- (c) measuring an arc height of a component under test subsequent to a shot peening process;
- (d) correlating the measured arc height to a measured arc height of an aluminum Almen test strip exposed to the shot peening process;
- and
- (e) creating a shot peening test kit in accordance with (a)-(d).
