Tool trajectory generation based on tool deflection effects in the flat-end milling process (II) - Prediction and compensation of milled surface errors

In this paper, we present the optimum reference for the compensation of too l trajectory to fulfill the imposed tolerances in flat-end milling process. First, Eve suggest the milled surface prediction methods considering the t ool deflection effects. Based on the predicted error distributions, we prop ose a cutting process simulation method, which can verify (1) if the tolera nce is fulfilled, and (2) if it is possible to compensate the surface error s by the proposed approaches presented in Part I, before the real milling o peration begins. As the result of our research, we could make our compensat ion method very applicable for real industrial cases by considering the imp osed manufacturing tolerances. Required experiments for practical examples were performed, and it was found that the results were in good agreement wi th our predictions.
