The following paper aims to apply the concept of the small displacements torsor (SDT) in order to predict the defects of a part resulting in successive machining set-up. The proposition is to enlarge the 1D dispersion method to a 3D analysis of the feasibility of a machined part. This paper follows our previous works on the development of a method using this concept to simulate a manufacturing process. These developments are adapted to the turning process and its particularities. The relevant parameters allowing to describe the manufacturing and positioning defects are determined. These defects are analyzed with regards to the functional specifications of a part.
