The digital revolution is now breathing the walls of manufacturing as media, banking, consumer goods, healthcare and other industries are constantly disrupted. Digital manufacturing provides the ability to conduct a full production process in a virtual world. In this way, engineers digitally describe, schedule, build 3D models using CAD software, track, build analysis. Digital manufacturing involves the end to end digitization of all physical assets and their integration in to digital eco systems with value chain partners. Digital manufacturing is the driver for the fourth industrial revolution which is termed as Industry 4.0. This paper explains about the digital manufacturing technologies used for the development of missile.Keywords

Electron beam additive manufacturing is a novel method of manufacturing parts directly from digital STL file by using layer by layer material build-up approach. This is tool less manufacturing methodology to produce fully dense metallic parts in short interval of time, with high precision. Features of additive manufacturing like freedom of part design, part complexity, light weight, part consolidation and design for function are depositing particular interests in metal additive manufacturing for aerospace, oil & gas, marine and automobile applications. This research paper presents overview of sciaky’s electron beam 3D metal printing technology, materials, applications.Keywords

The main objective of this paper presents the analytical evaluation and mathematical modeling of hoop stresses of metallic cups of materials such as AA1100 and galvanized commercial steel in hydro forming deep drawing of n-sided polygonal cup. It is very important to find the magnitude of these stresses produced within the flange area. Two types of stresses will be established in the flange region. One of it is radial stress. It usually occurs radial outward from the side of the cup to the outer side of the blank material. Another is hoop stress. It can be generated in the flange. It is compressive in nature and perpendicular to the radial lines drawn to the side of the blank from the job axis. It is either parallel to the blank circumference or tangential to it. Inside of the blank material, these two stresses will be created by the use of punch forKeywords
