To control and to optimise the product/process pair, manufacturing companies are more and more directed to use software tools performing virtual simulations. In this way, let us consider that one important aim of the virtual or numerical simulation of process planning is to study and take into account the machining dispersions. The global intend is to predict the intervals of tolerances of a series of manufactured parts and to compare with the specifications due to the design office. The general objective of this work is to extend the field of application and to increase the knowledge about machining dispersion simulations. This study, based on design of experiment, aims to confirm the hypothesis retained for an initial model designed to help process planning and validate chronology, sequencing, and elementary operations. In this paper, an extent of the simulation model of dispersions in turning process first exposed in [W1], is developed. This initial work is based on the characterisation and the taking into account of the geometrical default generated by the turning process. An integration of the parameters relative to the cutting conditions and to the machined and cutting materials is now proposed. The link between these parameters and the input data of the initial model is explained. An application is developed to illustrate the associated methodology. The effect of each cutting parameter on machining dispersions has been shown and quantified.
