This paper describes a system to predict positions and dimensions of burrs formed in end-milling. Two kinds of burr models are applied for the prediction, that is, "Poisson burr model" estimates the burr formed by cutting edge entering to a workpiece and "Rollover burr model" estimates the burr formed by cutting edge leaving from a workpiece. In the prediction, geometric parameters of a cutting tool, physical properties of a workpiece, cutting conditions and cutting force are used. Some values of these are derived by NC simulator. Predictions and examinations were performed in some cutting conditions. The predictions of exit burr agree with the results of examinations.
