Ovality and Bow Defect of Pre-punched Sheets in Roll Forming of Trapezoidal Sections
Roll forming process is used for manufacturing sheet metal parts by successive bending and creating the final shape with gradual deformation. In this article, deformation of a pre-punched sheet due to the roll forming process was studied. Two main defects in the roll forming process are ovality of holes and bow defect. The ovality of the hole is influenced by the process parameters including sh...
متن کاملDuctile Failure in High Strength Steel Sheets
Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usag...

15 صفحه اولPunched-Card to Magnetic-Tape Converter
THE principal devices for converting source data to magnetic tape recording for Univac* are the card-to-tape converter and the Unityper. * Unityper is the, logical conversation medium for input of 'otherwise untreated data. Files of punched cards, however, represent to the owner an investment of time and expense in preparing material for other treatment. The card-to-tape converter provides a me...
متن کاملA punched-card system for the laboratory.
A punched-card system was developed to simplify the administrative aspects of the clinical chemistry laboratory. In it a three-part requisition and samples are matched and given a laboratory number. The third copy of the original laboratory requsition is a charge card also used as a name file for the day. Prepunched cards, coded for laboratory tests, are used for each test requested. The labora...
