Book excerpt: This session centered on the current capabilities of several commercially available graphics systems in parts nesting and computer aided shipyard drafting. Three representatives of graphics system vendors participated on a panel to answer questions from the audience concerning their products' capabilities and graphics systems in general. These representatives were Dr. Robert Cowen of Computervision Corporation. Robert N. Hickox of Adage, Inc. and Lou Melancon of Auto-Trol Corporation. In addition, a representative of the italian yard italcantieri S.p.A. was on hand to relate that yard's experience in the use of Adage equipment for interactive nesting. Of interactive nesting italcantieri, in response to questions from the floor, has seen a reduction in nesting labor as a result of using their system from between 20,00 to 24,000 man-hours per year. He further stated this effort represented the production of some 2500 nest tapes. On the topic of system reliability the vendors reported uptimes for their systems in excess of 95%. The cost of these systems was also questioned. Without a clear description of the application, number of users, etc. of such a system, the vendors were able to respond only that the costs ranged from around $100,000 for a single user drafting system on up. On the topic of computer aided design systems two members of the audience reported on the Navy's development efforts in this area. Two current applications cited in the Navy are a computer aided hull lines generation system employing interactive graphics and a graphics assisted ship's arrangements program.

This book was released on 1979 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the REAPS Technical Symposium. Paper No. 24: Group Technology and Automated Process Planning, a Change in Management Strategy. The trend toward increased customization is increasing the problems associated with batch manufacturing, both in design and manufacturing itself. Group technology helps to solve these problems and is thus attracting great interest. The benefits of group technology in such applications as design retrieval, design standardization, standardization of machine tool routings, automated process planning, and machine tool investment can bring about dramatic savings in the multibillion dollar manufacturing industry. Three or four years ago, only a handful of companies were interested in group technology. Today, many companies, including a number considered to be highly conservative, are seriously considering or have adopted group technology systems. This increased interest is a reflection of a growing awareness of the potential benefits of group technology, particularly for batch manufacturing. These advantages can apply to both design and manufacturing.

Book excerpt: The use of computers has made a tremendous impact on the ship design and the ship building processes in recent years. Designers utilize special programs to optimize their design according to economic and performance requirements. for a certain type of vessel in a certain type of service. From this iterative process, the optimum parameters are obtained and the preliminary design carried out.

This book was released on 1976 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The law that created the National Aeronautics and Space Administration directed NASA to provide "for the widest practicable and appropriate dissemination of information concerning its activities and results thereof." Assuming that the research and development costs supported NASA's primary space and aeronautics missions, then any secondary use of this technology for other non-aerospace purposes would provide an additional benefit to our national economy. The the exploration of space and the advancement of aeronautics generates innovations in almost every field of science and technology and, therefore, provides us with the broadest possible technical base to stimulate progress in areas not even remotely connected to the original research. NASA has established a national network of dissemination centers to serve industry by searching what has become the world's largest data bank of technical information. Technical information that has been provided through this network has resulted in many useful applications and new products. Spinoffs of technology have ranged from medical devices for the handicapped to patching materials for street maintenance and countless applications in between.

This book was released on 1977 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total design and production of a new product is particularly a problem for large projects, for example special purpose ships and offshore structures, where a close co-operation and control is demanded by owners, classification societies and officials in general. In today's situation, lacking as it is in new orders, the builder is often forced by the terms of the contract to spend only a very short period of time on design activities. Shortening the leadtime for design and work preparation is as very important for the ability of a company to compete. Preferably this shortening of lead- time must not induce extra costs or be at the expense of product quality. Based on our experiences in the use of EDP as well as our plans for further development, we will focus on what has been done and what may still be done to strengthen our competitiveness in this area.

Book excerpt: In March of 1976, the decision was made at Port Weller Dry Docks to purchase an in-house computer system to expand our use of computer programs and to update our present systems. At that time two systems were in operation at Port Weller. The accounting and labor distribution programs were executed on a Litton-McBee paper tape oriented computer system, and the production planning and control, numerical control, and design programs were executed on a UNIVAC 1108 time sharing system using a remote batch terminal for data transmission.

This book was released on 1976 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the decision was made to proceed with the development of the Interactive Graphics version of the SPADES System, a list of requirements and goals was made. One of the major considerations was to have total interchangeability between the graphic and the batch mode of the System such that rework could be processed easily, whether the original work had been done through the 'CRT' or in batch. As much as we would like to think otherwise, experience has taught us that changes and revisions are an ever present way of life during the ship design and construction process. The requirement was also set that none of the SPADES management and control features would be compromised because of the graphic. In order for the graphic version to be a useful production tool, the user would have the capability of totally checking parts and/or burning tapes generated through the CRT without having to wait for a drafting machine drawing and/or computer printout. It was also decided that the user would have the capability of switching from one program to another directly from the tube without re-initializing any program at the central computer. The plans called for four CRTs to be on simultaneously, and for at least one batch SPADES program to be also running at the same time. This requirement caused the only major modification of the then existing SPADES System in order to allow different programs to read and write records from the same data base at the same time. By combining the use of virtual memory capability of the computer and judicious use of overlay, all the applicable programs have been linked together in one executable module.
