Skin Model Based Tolerance Analysis [Elektronisk resurs]

• Skin model of a workpiece is a discrete geometry representation of the physical interface between the workpiece and its environment. Skin model and the related operations are defined in GPS ISO 17450-1 standard. Skin models, in the form of point clouds as those obtained from scanning or any discrete geometry format, captures the variations more accurately and provide opportunities for more accurate variations and tolerances analysis. However, various variation and tolerance analysis methods use different forms of variation representations such as vectors, displacement torsors, etc. In order to use these methods with skin models, the variations need to be extracted from the skin model appropriate to the analysis method. This paper presents and illustrates methods just to do such reformulations.
