Over the past 25 years, the shipbuilding industry has gone from full scale faired hull design with manual part definition and preparation to the use of computerized designs and computer assisted part preparation. During this period of growth, the equipment and the computer systems adopted have varied from yard to yard to suit the needs at the time of purchase. In addition, existing facilities and the historical mode of operation has varied from yard to yard. Therefore, the methods for selecting plate sizes, for nesting parts on the plate and the requirements for marking and labeling cut parts vary from yard to yard. In preparing this report, the above has been recognized. The various factors that play a role in the final and successfully marked parts are discussed under the appropriate headings. It is hoped that the information contained herein will not only be found interesting and informative, but that it will also be helpful in lowering costs and improving production. / NOTE:Technical rept. |
