On Practice and Theory of Constructive Composite Geometry and Topology

November 25, 2019
Author(s)
Thomas D. Hedberg Jr., Allison Barnard Feeney, Vijay Srinivasan
This paper synthesizes a theory from industrial best practices codified in recent standards. Recent editions of ASME and ISO standards codify the evolving industrial best practices in defining and modeling the information about products made from fibrous

Constrained Least-Squares Fitting for Tolerancing and Metrology

July 1, 2019
Author(s)
Craig M. Shakarji, Vijay Srinivasan
Recent years have seen a remarkable emergence of a particular type of least-squares fitting, called constrained least-squares fitting, in national and international standards on tolerancing and metrology. Fitting, which is called an association operation

Cyber-physical Systems Engineering for Manufacturing

October 7, 2016
Author(s)
Allison Barnard Feeney, Simon P. Frechette, Vijay Srinivasan
There is a convergence of interests in cyber-physical systems, systems engineering, and manufacturing innovation in the United States. The U.S. National Institute of Standards and Technology (NIST) has undertaken research programs in smart manufacturing

The New Frontiers in Computational Modeling of Material Structures

February 23, 2016
Author(s)
Vijay Srinivasan, Jarek Rossignac, Vadim Shapiro, William Regli
We are witnessing the emergence of a new paradigm in the modeling of material structures. It stems from the digitization of manufacturing and is fueled by advances in additive manufacturing and material science. This paper strives to provide a critical

Datum Planes Based on a Constrained L1 Norm

December 1, 2015
Author(s)
Craig M. Shakarji, Vijay Srinivasan
This paper has two major goals. First, we present an algorithm for establishing planar datums suitable for a default in tolerancing standards. The algorithm is based on a constrained minimization search based on the L_1 (L1) norm after forming a convex

A Constrained L2 Based Algorithm for Standardized Planar Datum Establishment

November 18, 2015
Author(s)
Craig M. Shakarji, Vijay Srinivasan
For years (decades, in fact) a definition for datum planes has been sought by ASME and ISO standards writers that combines the contacting nature of traditional surface plate mating with a means of balancing rocking conditions when there is a centrally

An improved L1 based algorithm for standardized planar datum establishment

October 1, 2014
Author(s)
Craig M. Shakarji, Vijay Srinivasan
This paper has two major goals. First, we present an algorithm for establishing planar datums suitable for a default in tolerancing standards. The algorithm is based on a constrained minimization search based on the L_1 (L1) norm after forming a convex

Geometric Interoperability via Queries

May 19, 2014
Author(s)
Vijay Srinivasan
The problem of geometric (model and system) interoperability is a non-trivial generalization of the classical problem of part interchangeability in mechanical assemblies. Interoperability subsumes the challenging problems of geometric model quality

Metrological challenges introduced by new tolerancing standards

February 13, 2014
Author(s)
Ed Morse, Yue Peng, Vijay Srinivasan, Craig M. Shakarji
The recent release of ISO has provided designers with a richer set of specification tools for the size of part features, so that various functional requirements can be captured with greater fidelity [2]. However, these tools also bring new challenges and
