Tolerance Analysis by Polytopes
CoRR, 2015 To determine the relative position of any two surfaces in a system, one approach is to useoperations (Minkowski sum and intersection) on sets of constraints. These constraints aremade compliant with half-spaces of R^n where each set of half-spaces defines an operandpolyhedron.

Manufacturing Signature for Tolerance Analysis
Journal of Computing and Information Science in Engineering, 2015 Every manufacturing process leaves on the surface a signature, i.e., a systematic pattern that characterizes all the features machined with that process. The present work investigates the effects of considering the manufacturing signature in solving a tolerance stack-up function.
