Surface Roughness Modeling Based on Surface Roughness Feature Concept for High Speed Machining

This paper explains the concepts to develop a Model of Surface Roughness in order to help researchers to model predictors for high speed machining, also a concept of a surface roughness feature (RaF) is introduced. A RaF is an information piece that shows the factors used by a Ra prediction technique associate with a specific geometric feature. The surface roughness information model is a repository of the RaFs designed to focus on particular workpiece geometries. The Ra predictor developer can design the content of the Ra information model according with his Ra prediction technique to be developed. Each RaF matches with a prediction technique to form RaF predictors and they are united to form a general Ra predictor for the entire workpiece profile.Copyright © 2005 by ASME
