Rahou}, country = {}, institution = {}, abstract = {The study of the generated defects on manufactured parts shows the difficulty to maintain parts in their positions during the machining process and to estimate them during the pre-process plan. This work presents a contribution to the development of 3D models for the optimization of the manufacturing tolerances. An experimental study allows the measurement of the defects of part positioning for the determination of ε and the choice of an optimal setup of the part. An approach of 3D tolerance based on the small displacements method permits the determination of the manufacturing errors upstream. A developed tool, allows an automatic generation of the tolerance intervals along the three axes.}, journal = {International Journal of Industrial and Manufacturing Engineering}, volume = {4}, number = {5}, year = {2010}, pages = {464 - 468}, ee = {https://publications.waset.org/pdf/6049}, url = {https://publications.waset.org/vol/41}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 41, 2010}, }
