Deep drawing of 304 L Steel Sheet using Vegetable oils as Forming Lubricants
The study involves the evaluation of deep drawing process using two non edible oils, Pongam (Pongammia pinnata) and Jatropha (Jatropha carcass) as metal forming lubricants. Experiments are conducted on 304L steel sheets under the raw and modified oils with suitable punch and die on a hydraulic press of 200 ton capacity. The punch load, draw-in-length and wall thickness distribution for deep dra...
متن کاملPancreas Transplantation and Report of 1st one in IRAN
SUMMARY Since 1923, the type I diabetic patients are treating with injections of insulin. Mortality of these patients decreased, comparing with noninsulin using patients, but many of them developed complications of diabetes mellitus, like nephropathy, retinopathy and neuropathy. The choice for treating this diseas and preventing its complications is pancrease transplantation, The 1st pancreas...
متن کاملWarm Deep Drawing of Aluminium Sheet
Aluminium sheet drawing processes can be improved by manipulating local flow behaviour by means of elevated temperatures and temperature gradients in the tooling. Forming tests showed that a substantial improvement is possible not only for 5xxx but also for 6xxx series alloys. Finite element method simulations can be a powerful tool for the design of warm forming processes and tooling. Their ac...
متن کاملStudy of Traverse Grinding Process (1st Report) Accumulation Phenomenon and Size Generation Mechanism in Traverse Grinding
plicated processes on the wheel surf ace along the wheel width. In order to make these processes clear, the experimental analysis of traverse grinding was conducted by widely changing the speed ratio, Kv, the setting depth of wheel, ‡TMT, and the number of total steps, m, (the ratio of the wheel width over the traverse feed per one revolution of the workpiece). The following results were obtain...
