Additives and EGR Process for the Exhaust Gases in Compression Ignition Engine
Abstract: Exhaust gases is the most prompt topic in current situation. Exhaust gases badly affect the environment, human and other living organism so, controlling of exhaust gases is very essential. Today automobile vehicles particularly diesel engine vehicles emit more exhaust gases, so for the controlling of exhaust gases we can use additives in fuel and EGR process together. When the additives are mixed with fuel, a cylinder pressure decreases and ignition …

Influence of Cutting Speed and Tool Angles on Tool Forces in Turning of Steel Reinforced Polymer Composites
Abstract: Turning of steel fiber reinforced polymer composites is quite different compared to machining of conventional metals and alloys. Hence an experimental investigation on orthogonal turning was carried out in an effort to analyze the variation in cutting force and thrust force for different cutting speeds, depth of cuts and tool rake and relief angles using HSS tool. The cutting and thrust force values were found to be decreasing with the …

The Study of Hole Flanging Process of Advanced High Strength Steel
Abstract: 800x600 In the hole flanging process, predetermine hole in the sheet is enlarged by using the larger punch radius for forming the flange. This process is widely used in the various industries. In this study, the hole flanging process in a circular sheet of advanced high strength steel is carried out using elasto-plastic finite element numerical simulation. The lip shape behavior and punch load variation in hole flanging process is …
