Affiliated at NIST with Intelligent Systems Division since September 1991
Working on automated reasoning.
Working on various aspects of metrology automation.
Active, as a member of the DMIS National Standards Committee, in developing the DMIS language for control of coordinate measuring machines.
Active in developing STEP, the international standard for product model data, particularly STEP parametrics and STEP Manufacturing.
Built software for an advanced feature-based control system for 3-axis machining application.
Built software system to interpret the DMIS language for control of coordinate measuring machines.
Developed canonical functions for 3-axis to 6-axis machining.
Built software systems to interpret various dialects of the RS274 language for control of numerically controlled machining centers.
Studied control system architectures for robotic applications and computer integrated manufacturing.
Affiliated at NIST with Manufacturing Systems Integration Division formerly Factory Automation Systems Division, 1984 to 1991
Developed design concepts and software for the Automated Manufacturing Research Facility Vertical Workstation, including a feature-based design protocol, an interactive design editor, automated mechanical drawing, automated process planning, part and environment modeling, design and process plan verification, automated tool path generation, automated generation of NC-code, local database management, automated generation of LISP code, automatic feature recognition, and automatic generation of hole-milling code with in-process metrology.
Active in developing STEP, the emerging international standard for product model data.
Developed design concepts and wrote all software for the Off-Line Programming System, a system for automatically generating NC-programs from STEP data. Developed pocket milling with tool engagement detection and built it into the system.
Built translator that converts a boundary representation of a design from a proprietary format (a Parasolid transmit file) to a STEP physical file.
Developed several models for automated manufacturing in EXPRESS, the STEP information modeling language. Built prototype EXPRESS editor.
Studied and reported on a STEP application protocol framework.
Staff Director, Subcommittee on Science, Research, and Technology (SRT), September 1982 - February 1984. Science consultant with SRT 1975 - 1982.
Worked on innovation and productivity topics 1979 - 1982, including: technology transfer, centers for industrial technology, national medal of technology, small business innovation, robotics, patent policy, technology and employment, the human factor in innovation and productivity, tax policy, university-industry relations, and a proposed National Technology Foundation.
Principal House staffer for the Stevenson-Wydler Technology Innovation Act of 1980, which covered the first three items above.
Published House Newsletter on Innovation and Productivity for several years.
Worked primarily on authorizing legislation and oversight of the National Science Foundation 1975 - 1979, including special studies of peer review, program managers, the U. S. Antarctic program, and other topics.
Worked on authorizing legislation and oversight of the National Institute of Standards and Technology (under its former name).
Principal House staffer for initial enactment of the Earthquake Hazards Reduction Act.
