Integration of thermomechanical strains into tolerancing analysis

Semantic Tolerancing

Recently we developed a new tolerance modeling scheme, semantic tolerance modeling, to enable interpretable and accurate tolerance analysis. In this paper, a new dimensioning and tolerancing practice, semantic tolerancing, is proposed with the theoretical support of semantic tolerance modeling. Based on the principles of interpretability, this tolerancing approach allows for better design inten...

Software Defect Prevention through Orthogonal Defect

“Quality is never an accident; it is always the result of intelligent effort” [10]. In the process of making quality software product, it is necessary to have effective defect prevention process, which will minimize the risk of making defects /errors in software deliverables. An ideal approach would involve effective software development process with an integrated defect prevention process. Thi...

Tolerancing Optical Systems

Introduction Tolerancing an optical system has traditionally fallen between an art and a science. Experience and intuition has driven optical engineers for decades in deciding the appropriate tolerances to place on optical components and the mechanics holding them. In an effort to systematically quantify this process, mathematical methods have been reported by Warren Smith, Ronald Willey, and o...
