Variables in Design: Analysis and Model Building

Release Date:
9/12/2012 9:00 PM

Anthony Chory, mechanical engineering, features Anthony Chory 


The Alvine Engineering Professional Effectiveness and Enrichment Program will present a lecture that summarizes some useful information extracted from the book “STATISTICS FOR EXPERIMENTERS”, An Introduction to Design, Data Analysis, and Model Building, Authored by Box, Hunter and Hunter. “How to determine which variables of a manufacturing process makes some parts turn out good and some parts turn out not so good,” says Chory.

Using some basic statistical assumptions, multiple graphics and some statistical analysis, examples are analyzed to determine the effect of manufacturing variables.   The method provides a numerical factor to each variable and combinations of each variable.


Chory earned his BS in Mechanical Engineering from UMASS Lowell in 1978 and his MS in Mechanical Engineering from the University of Bridgeport in 1985.   He has worked in Transmission Design and Development at Sikorsky Aircraft since 1978.   Mr. Chory is currently Chief of Transmission Design for all military aircraft transmissions.  He also provides technical support to other Sikorsky Transmission production and development programs along with consulting for other UTC transmission programs.  He has been responsible for the Black Hawk transmission system for over 25 years working to make it the most reliable and bench-marked transmission in the helicopter industry.  Prior to his responsibilities as the Chief of H-60 Design, Mr. Chory had extensive experience in Finite Element Analysis, gear analysis and other general types of transmission and structural analysis.  He was also was responsible for Research and Development programs including the 30000 RPM Spring Clutch development program used on the RAH-66 Comanche program and the MM&T Composite Black Hawk Intermediate Gearbox Program which was fabricated and tested.  His design, production and field experience has given him the skills to not only develop new transmission but insure they are producible, durable and highly reliable.


Nov. 6, from 6 p.m. – 7:30 p.m.

The University of New Haven is a private, top-tier comprehensive institution recognized as a national leader in experiential education. Founded in 1920 on the campus of Yale University in cooperation with Northeastern University, UNH moved to its current West Haven campus in 1960. The University provides its students with a unique combination of a solid liberal arts education and real-world, hands-on career and research opportunities. UNH enrolls approximately 6,400, including nearly 1,800 graduate students and more than 4,600 undergraduates – the majority of whom reside in University housing. Through its College of Arts and Sciences, College of Business, Henry C. Lee College of Criminal Justice and Forensic Sciences, Tagliatela College of Engineering, and College of Lifelong & eLearning, UNH offers 75 undergraduate and graduate degree programs. UNH students have access to more than 50 study abroad programs worldwide and its student-athletes compete in 16 varsity sports in the NCAA Division II’s highly competitive Northeast-10 Conference.
