The objective of the study is to show that a one-way machining simulation can be qualitatively satisfactory to validate a range of parts machined on a manufacturing with machine-tools 3 axis, even if they must meet geometric tolerances. A reflection on a method of distribution of defects is proposed. A compliance criterion based on the variance domain differences is used. Then, the main component analysis of defects is applied. The proposed model is validated by experimental analysis for which the distributions of defects are given. The results show the major character of the dimensional defect component compared to the angular components (repositioning and machining). A unidirectional approach seems so reliable when the manufactured part and its range of machining remains modest complexity.
