Unformatted text preview: the real and the simulated surface signatures obtained. The left hand side of the figure shows the predicted and the real textures realized by a spiral cycle. The different texture zones of the machined surface are accurately described by the model. So the model can be advantageously used to predict the texture or roughness induced by given cutting parameters, tool geometries and machining strategies. The right hand side figure shows the predicted and the real signatures obtained. Both curves have been centered and reduced in order to be correctly compared. The predicted and the real signatures are in good agreement although if some differences can be noticed. They can be partly explained by the plastic deformation and shearing induced by cutting or geometrical defects of the milling tool. Figure 8; Simulated and real signatures 200 5. CONCLUSION S. Aranda et al. In this paper a model has been presented to predict the signature of the end milling machining process. This model differentiates from the previous approaches by the...
