The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...
کشش عمیق از مهمترین فرآیندهای شکل دادن ورق است که به طور وسیعی در صنعت برای تغییر شکل ورق های فلزی و تبدیل آن ها به قطعات توخالی و بدون درز به کار می رود.این فرآیند کاربردی وسیع در تولید قطعاتی با شکلهای متنوع و ابعاد مختلف برای عرصه¬های مختلف تولیدی دارد که در برگیرنده قطعات بسیار کوچک و مورد نیاز در صنایع برق و الکترونیک تا ابعاد چند متری در شاخه¬های دیگر صنعت می¬باشد. گسترش روشهای ویژه در فر...
Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...
Equal channel angular pressing has been used to refine the grain size of commercially pure titanium (grade 2) as well as other metals and alloys. Titanium grade 2 is usually processed at about 350 °C because it lacks sufficient ductility at lower temperatures. The warm processing temperature limits the capability of the equal channel angular pressing technique in improving the strength of titan...
Device drivers account for a substantial part of the operating system (OS), since they implement the code that interfaces the components connected to a computer system. Unfortunately, in the large majority of cases, hardware vendors do not release their code, making the analysis of failures attributed to device drivers extremely difficult. Although several instrumentation tools exist, most of t...
The present research work is concerned with the effects of optimum process variables in elevated temperature hydro-mechanical deep drawing of 5052 aluminum alloy. Punch-workpiece and die-workpiece friction coefficients together with the initial gap between the blank holder and matrix were considered as the process variables which, in optimization terminology, are called design parameters. Since...
