Modification in Forming Die to Overcome Manufacturing Process
International Journal of Scientific & Engineering Research Volume 11, Issue 7, July-2020 ISSN 2229-5518 41 Modification in Forming Die to Overcome Manufacturing Process Limitation Prof.B.R.Chaudhari[1], PrathmeshKulkarni[2], Tejas Potdar[3], Omkar Pawar[4], Akhilesh Nikam[5] Abstract—Forming of sheet metal is common and vital process in manufacturing industry. Sheet metal forming is the plastic deformation of the work over an axis, creating a change in the parts geometry. Generally, there are two parts used in forming process; one of the part is punch which performs the stretching, bending and blanking operation and another is Die block which secularly clamps the workpiece and same operation as punch. Forming processes are particular manufacturing processes which make use of suitable stresses like compression, tension, shear, combined stresses which causes plastic deformation of the material to produce required shapes. During Forming process, no material is removed i.e. they are deformed and displaced. Some examples of forming processes are Forging, Sheet metal working, thread rolling, Electromagnetic forming, Explosive forming, rotary swaging, etc. Here the problem statement of the project is to combine these two parts design in one forming die which is now manufacturing separately on two different forming dies.

Manufacturing Glossary
MANUFACTURING GLOSSARY Aging – A change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after a hot-working operation or a heat-treatment (quench aging in ferrous alloys, natural or artificial aging in ferrous and nonferrous alloys) or after a cold-working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy. Abrasive – Garnet, emery, carborundum, aluminum oxide, silicon carbide, diamond, cubic boron nitride, or other material in various grit sizes used for grinding, lapping, polishing, honing, pressure blasting, and other operations. Each abrasive particle acts like a tiny, single-point tool that cuts a small chip; with hundreds of thousands of points doing so, high metal-removal rates are possible while providing a good finish. Abrasive Band – Diamond- or other abrasive-coated endless band fitted to a special band machine for machining hard-to-cut materials. Abrasive Belt – Abrasive-coated belt used for production finishing, deburring, and similar functions.See coated abrasive. Abrasive Cutoff Disc – Blade-like disc with abrasive particles that parts stock in a slicing motion. Abrasive Cutoff Machine, Saw – Machine that uses blade-like discs impregnated with abrasive particles to cut/part stock. See saw, sawing machine. Abrasive Flow Machining – Finishing operation for holes, inaccessible areas, or restricted passages. Done by clamping the part in a fixture, then extruding semisolid abrasive media through the passage. Often, multiple parts are loaded into a single fixture and finished simultaneously. Abrasive Machining – Various grinding, honing, lapping, and polishing operations that utilize abrasive particles to impart new shapes, improve finishes, and part stock by removing metal or other material.See grinding. -

Effect of Homogenization on Recrystallization and Precipitation
Materials Transactions, Vol. 49, No. 2 (2008) pp. 250 to 259 #2008 The Japan Institute of Metals Effect of Homogenization on Recrystallization and Precipitation Behavior of 3003 Aluminum Alloy Hsin-Wen Huang, Bin-Lung Ou and Cheng-Ting Tsai Department of Mechanical Engineering, National Central University, Chung-Li, Taiwan 320, R.O. China This investigation studies 3003 aluminum alloys for automobile heat exchangers. The effects of precipitation in homogenization treatments, recrystallization in extrusion and brazing on extrusion forming ability and final material properties are examined. At first, fine second phase particles were precipitated during the 460C Â 9 h homogenization treatment and coarse particles were precipitated by homogenization treatments with 600C Â 9 h. Second, when the precipitation were not plentiful and fine enough during extrusion, the amount of solution dominated the extrusion breakout pressure, and recrystallization was easier; on the contrary, the domination state was replaced by plentiful and fine precipitated particles, and recrystallization became more difficult. Additionally, the hardness after extrusion was lower in the complete recrystallization position, and higher in the incomplete recrystallization position. Finally, in brazing, the sample under the 460C Â 9h condition (a) underwent full recrystallization from partial recrystallization with a reduction in strength; the local position of the edge of the sample under the 600C Â 9h ! 460C Â 3 h condition (c) exhibited a second recrystallization and a significant drop in hardness.
