The machined surface - time series modelling
The applicability of time series modelling techniques to the simulation of machined surface profiles is discussed. The methods are then illustrated for a second-order autoregressive model with a normal amplitude distribution. In order to allow generation of non-normal surface profiles the relations between the surface height third moments and residual third moments together with similar relations for the fourth moments, and hence skew and kurtosis, are also given for first- and second-order autoregressive models. Examples are then shown for each of these cases. ?? 1979.
