Abstract
In order to properly characterize the surface profiles produced by abrasive waterjets (AWJ), a hybrid model is proposed. To obtain this model, the significant sinusoids corresponding to the discrete spectra must first be removed from the original profile data. Then the residuals are fitted employing autoregressive moving average (ARMA) models. The criterion guarantees that hybrid model always provides a more accurate description of the profile than the pure ARMA model. A linear least squares algorithm (AIC) has been presented to identify these sinusoidal components. The effectiveness of the model in comparison with ARMA has been verified through modeling AWJ generated surface profiles.
