System for Computer Aided Cavity Layout Design for Diecasting Dies
Diecasting is one of the forming methods which is used for producing large number of components with good surface finish by injecting cast alloys in a metal mould under high pressure. Design of a diecasting die requires human expertise and is normally performed by trial and error method, which leads to monetary and time loss. Automation at initial die design stage will result in higher producti...
متن کاملRheo-Cast Microstructure and Mechanical Properties of AM60 Alloy Produced by Self-Inoculation Rheo-Diecasting Process
Rheo-forming is becoming the choice for production of high quality parts with diminished defects and fine integrity. In this paper, the novel self-inoculation rheo-diecasting (SIRD) process, in which semisolid slurry is produced by mixing two precursory solid and liquid alloys and subsequently pouring them through a multi-stream fluid director, has been proposed. Microstructural characteristics...

هدف ما در این پایان نامه طراحی و ساخت سیستم مولد پلاسمای فلزات قلیایی به نام q-machine vertical می باشد.این سیستم از چند قسمت تقسیم شده است که عبارتند از: 1- محفظه خلا با اتصالات از نوع استاندارد cf و خلا اولیه بین6-10 تاtorr 8-10که بصورت استوانه ای و سه تکه و از جنس استنلس استیل 316 می باشد. 2- آهنرباهای الکتریکی: که وظیفه دارند میدان مغناطیسی محوری یکنواخت وثابتی در حدود 5/0 تسلا در طول قس...
Macro-Segregation and Microstructural Characteristics in Rheo-Diecasting of a High Strength Al–4.8mass%Si–0.7mass%Mg Alloy
Rheo-diecasting with electro-magnetic stirring has been carried out to investigate macro-segregation and microstructural characteristics of a high strength AlSiMg alloy under various process conditions. The amount of initial heterogeneous nucleation and the degree of temperature uniformity in the slurry are dependent on the superheat of the melt at pouring into the slurry making vessel. The f...
متن کاملMachine scheduling for multitask machining
Multitasking is an important part of today’s manufacturing plants. Multitask machine tools are capable of processing multiple operations at the same time by applying a different set of part and tool holding devices. Mill-turns are multitask machines with the ability to perform a variety of operations with considerable accuracy and agility. One critical factor in simultaneous machining is to cre...
