His early assignments were with the General Engineering Laboratory and the Knolls Atomic Power Laboratory in Schenectady. N. Y. He joined the Marine Turbine and Gear Department in 1968 as Manager Engineering Administration. and assumed his present assignment as Manager Engineering Resource Planning & Administration in 1976. Mr. Gingrich was instrumental in procuring the Interactive Graphics System for the Medium Steam Department. having headed up the Study Team and is now responsible for the Interactive Graphics Systems management including new procurements. He is a member of the American Institute of Design Drafting and is currently the Chairman of the Computer-Aided Drafting Committee in that organization. Mr. Reinhold L. Winter is a graduate of the General Electric Apprentice Program and Salem State College from which he received his B.S. degree in Business Administration. He has nineteen years experience with the General Electric Company including eight years in Business Systems and Programming two years in Computer Operations Management and six years in his present position as Manager Engineering Business Systems. He was a member of the original Study Team that investigated and selected the present Applicon Interactive Graphics (IAG) equipment and currently is responsible for the management of software and hardware support for the ZAG Facility.

This paper discusses the Interactive graphics System used by the General Electric Company, Medium Steam Turbine Department (Engineering & Manufacturing) for designing, drafting, and manufacturing applications. A brief overview of the hardware malting up the system is described, followed by a more detailed description of the actual applications. Two-dimensional applications described include a Heat Balance Analysis, Flow Diagrams, and Electrical Schematics. A more fruitful area for increased productivity gains is described in the three-dimensional or mechanical applications including turbine design & layout and bucket design. coordination of the design with manufacturing for numerical control tape generation is described through CAM and Plate Frame Cutting applications. Finally, a short review of the engineering design work using Interactive graphics is discussed. Productivity gains of 2.6 to 1 are being realized, and the overall savings to the Medium Steam Department are outlined.

This paper presents an integrated approach to computer-aided Ship design for U.S. Navy preliminary and contract design. An integrated Hull design System (HDS), currently under development by the Hull Group of the Naval Sea Systems Command (NAVSEA 32). is the vehicle for the discussion. This paper is directed toward practicing ship design professionals and the managers of the ship design process. Primary emphasis of this paper, and of the development effort currently under way, is on aiding ship design professionals in their work. Focus is on integration and management control of the extremely complex set of processes which make up naval ship design. The terminology of the Ship designer and design Manager is used. The reader needs no familiarity with the technologies of computer science.

A computer aided Ship design (CASD) and a computer aided Manufacturing (CAM) program are described. The objective of the program is to provide the capability to design and manufacture towing tank models using interactive CASD and CAM techniques. A three dimensional interactive graphics device supported by a minicomputer is used to drive the design portion of the system. A microprocessor based graphics system, simply and directly interfaced to a CNC controller on the shop floor, is used to perform the post processing and drive the milling machine. Experiences with actual use of the system and the benefits derived from this use are discussed for an actual production job. © 1979 institute of Electrical and Electronics Engineers Inc.

作者： Satterfield, Steven G. Rodriguez, Francisco Rogers, David F. Computer Aided Design and Interactive Graphics Group Division of Engineering and Weapons AnnapolisMD21402 United States

ISBN: (纸本)9781450379083

This paper describes a stand alone graphics system utilizing a microprocessor based display controller with the capability of combining refresh with storage tube graphics. This combination is accomplished by utilizing the Write-Thru feature of a Tektronix 4014 display terminal. The display controller is a typical Z-80 microprocessor system interfaced to the 4014 by a standard Tektronix parallel interface. A portion of the Z-80 memory is used as the display buffer, allowing it to be divided into store and non-store (refreshed) segments. The microprocessor performs the conversion from the simple integer X,Y coordinates in the display buffer to actual Tektronix drawing commands. A second Z-80 microprocessor is used to perform graphical transformations and transfer the data from the PDP-11 host to the Z-80 display controller. The operations performed by the second microprocessor include translation, rotation and scaling. These operations are implemented by matrix multiplication of the user data by a user specified transformation matrix. The stand alone capabilities of the graphics system is made complete with interactive devices such as a tablet, analog dials, and function switches interfaced directly to the host computer. © 1978 Association for Computing Machinery.

This paper describes CAMILL, a system for computer aided milling of ship hull models defined with interactive graphics-The major hardware components of CAMILL are a mini-computer based refresh display and a three axis numerically | controlled milling machine. For hardcopy documentation there is a large flatbed plotter. The two major software components are an interactive display program and a cutting program. The interactive display program is the human interface and provides capabilities for creating and modifying the ship design. The cutting program is executed in an intelligent terminal interfaced to the milling machine-The data used by the cutting program is generated by the display program and stored on a magnetic cassete tape. This cassette is transferred to the intelligent terminal for use by the cutting program-The main function of the cutting program is to direct the milling of the desired ship hull.

AN OVER VIEW OF A CASDAC SUBSYSTEM—computer‐aided PIPING design AND CONSTRUCTION (CAPDAC)

引用

Naval Engineers Journal 1976年第5期88卷 87-98页

作者： SHERIDAN, HARRY C. THE AUTHOR:graduated from the Polytechnic Institute of Brooklyn in 1959 with a BS degree in Mechanical Engineering. He is presently employed as the Machinery Group Leader of the Computer-Aided Design Division in the Computation and Mathematics Department at the David W. Taylor Naval Ship Research and Development Center Carderock Laboratory. Prior to that he was the Service Piping Branch Head in the Design Division of the New York Naval Shipyard. He is a member of the American Society of Mechanical Engineers.

The Navy has begun developing a large‐scale integrated computer‐aided ship design and construction system CASDAC which comprises several subsystems. The topic of this paper is the computer‐aided Piping design and Construction system — CAPDAC. It will involve the use of computers and computer programs by which shipyard and design agent personnel can design piping systems and provide input to the planning and construction process. The progress of work on the system to date includes development of programs, meetings with industry, and an engineering analysis. This later effort Is outlined in some detail. The overall piping design process, Level II, III, and IV design requirements, computer based environment, integrated system, “stand‐alone” subsystems, “standalone” applications, and planning support and construction support aids are described. Current work on a piping composite drawing subsystem is reviewed and current efforts on automating the pipe fabrication process are discussed. © 1976 by the American Society of Naval Engineers, Inc.
