Ray, Steven R. – NIST (Contributor to Chapter 10) Chief of the Manufacturing Systems Integration Division,
Manufacturing Engineering Laboratory, National Institute of Standards and Technology (NIST). From a technical
specialty in process planning, he co-developed a neutral process plan model called ALPS (A Language for Process
Specification), and participated on the development of STEP Part 49 (Process Structure and Properties), on the
validation of STEP AP213 (Process Plans for NC Machining), and served as acting Chair of the IGES/PDES
Organization from 1989 to 1990. Dr. Ray received his Ph.D. in Mechanical & Aerospace Engineering from
Princeton University in 1981, and his Bachelor's degree in Physics from Bristol University, England in 1977.
the IGES Organization from June 1980 and subsequently, Chairman of the IGES/PDES Organization until October
1989. Edited IGES Versions 1-3. Mr. Smith achieved ANSI approval for IGES Version 1.0 then organized the ISO
TC 184/SC4 Subcommittee and served as Chairman and Secretary from 1984 to 1995. He chaired the U.S. TAG for
ISO TC 184/SC4 from 1984 to 1989. Gained approval for the Initial Release of the first twelve parts of ISO 10303
