Unformatted text preview: presents a summary of the validation method. From one side, a real sample as been machined. The employed cuttings parameters were: feed fd = 0.2 mm/tooth and cutting speed Vc = 100 m/min. The employed tool was a mono-bloc carbide milling tool with a diameter of about 10 mm and two cutting edges. This sample has been measured using an optical probe. The set of surface points, thus obtained, has been used to define the real surface signature. On the other hand, the model has been implemented on Microsoft Vb.net programming framework. A simulated surface was thus computed. Such calculations cannot be compared directly to measured coordinates because this latter data includes random perturbations of the measurement process. For that reason, a flat standard of very high quality was measured to characterize the signature left by the optical probe. This information was finally added to the theoretical distributions to simulate the effect of acquisition. Surface Best Fit 199 Figure 7; Model verification
