Mechanical designs can be complex involving numerous parts and sub-assemblies. In the manufacture of these parts and sub-assemblies, they are subjected to variation. Hence, a better understanding of their form, fit and function is vital. For better clarity and quality acceptance, more firms are now specifying their engineering drawings using GD&T symbols so as to better control its geometric and functional characteristics. Tolerance stackup methods are then used to ensure that the cumulative effects of these tolerances are acceptable to the functional aspects in a sub-assembly. In this course, a disciplined tolerance stackup and analysis approach would be applied on engineering part assemblies subject to different and multiple GD&T specifications. |
