| Summary: | Quallty of automotive starnping process is often related to quality characteristics of automotive stamped panels. These are the panel's dimensional stability measured by deviations of panel's geometical dimensions from the nominal design specification. Correspondingly panel geomefiry is deemed as one of the attributes to variation in stamping process other than material properties, stamping process variables and die engineering and construction (Hammet! Baron et al. 2000). More often that not, deviation in stamped automotive parts
are claimed as the atfribute of variations in assembly dimensions
(Gu'rnan, and tlammett 2003; Hammet! Baron, and Smith 2000;
Kuzna-Smith 2000; Y*9, and Treum 2004). This is because good
fits cannot be achieved wtren panels are of large variations. As such,
continuous efforts should be made in improving the qualtty
automotive stamping process by studyipg the dimensionat stability
of the stampedpanels. |
