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

Mitigating Ingredient Variability Risks with Smart Manufacturing

February 18, 2016
Author(s)
Frank H. Riddick, Evan K. Wallace, Jim Davis
Managing the design of products and the efficient execution of the manufacturing processes needed to produce them is an endeavor fraught with all manner of risks for manufacturing enterprises large and small. In certain industries, such as the food

Nanomanufacturing: a perspective

February 10, 2016
Author(s)
James A. Liddle, Gregg M. Gallatin
Nanomanufacturing, the scalable and economically-sustainable mass production of nanomaterials and devices, represents the tangible outcome of the nanotechnology revolution. Nanomanufacturing processes, in contrast to those used in nanofabrication for

Performance Evaluation of Human Detection Systems for Robot Safety

January 22, 2016
Author(s)
William P. Shackleford, Geraldine Cheok, Tsai H. Hong, Kamel Saidi, Michael O. Shneier
Detecting and tracking people is becoming more important in robotic applications because of the increasing demand for collaborative work in which people interact closely with and in the same workspace as robots. New safety standards allow people to work

A metamodel for optimization problems

January 8, 2016
Author(s)
Ibrahim Assouroko, Peter O. Denno
In mathematics, computer science, and operations research, mathematical optimization is the process of finding best feasible values (oftentimes maxima or minima) of a given objective that is modeled mathematically. This paper introduces the concept of a

Benchmarking Robot Force Control Capabilities: Experimental Results

January 7, 2016
Author(s)
Joseph A. Falco, Jeremy A. Marvel, Richard J. Norcross, Karl Van Wyk
Metrics and test methods are needed to characterize the control capabilities of robots with both intrinsic and extrinsic force sensing. The availability of these benchmarks will motivate research product development, and provide a mechanism for reporting

Flexible Lines with Setups: Analysis, Improvement, and Application

January 4, 2016
Author(s)
Cong Zhao, Jingshan Li, Ningjian Huang, John A. Horst
Setup times commonly exist in many flexible manufacturing lines to adjust tools and carry out safety and quality checks during product changeovers. In this paper, a Markov chain model is introduced to study flexible manufacturing lines with setups. An

A defect-driven diagnostic method for machine tool spindles

December 31, 2015
Author(s)
Gregory W. Vogl, M A. Donmez
Simple vibration-based metrics are, in many cases, insufficient to diagnose machine tool spindle condition. These metrics couple defect-based motion with spindle dynamics; diagnostics should be defect-driven. A new method and spindle condition estimation

Integrating views of properties in models of unit manufacturing processes

December 28, 2015
Author(s)
Peter O. Denno, Duck B. Kim
This paper investigates the potential advantages and pitfalls of directly integrating knowledge expressed as predictive model equations with other process knowledge. The context of this integration is models of unit manufacturing processes. The method
