DIFFERENCE BETWEEN FORGING AND CASTING

Image
FORGING AND CASTING                Casting and forging are both industrial processes of metal forming and shaping. Different process used in different conditions. The main difference between casting and forging is that the metal is compulsory to heat and convert  into liquid stage in casting but in forging metal is converted into desire shape by applying pressure with or without applying heat. If the metal is preheated into forging it does not convert into liquid stage. But before differentiate this both terms; you have to know about what is casting and what is forging. Forging vs Casting: What is casting?                Casting is a process in which metal is heated until molten stage and pour this liquid metal into a mold or cavity where it is allow solidifying. This process converts the metal into desire shape. It is useful to make complex structure. Most of the ...

                            Cryogenic Rocket Engine Meaning of Cryogenics                         In physics, cryogenics is the study of the production of very low temperature(below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures Cryogenic technology : Cryogenic technology involves the use of rocket propellants at extremely low temperatures.  The combination of liquid oxygen and liquid hydrogen offers the highest energy efficiency for    rocket engines that need to produce large amounts of thrust.  Oxygen remains a liquid only at temperatures below minus 183 ° Celsius  and hydrogen at          below minus 253 ° Celsius.  History of Cryogenic Technology: The United States was the first country to develop cryogenic rocket engineswith RL-10 engines, re...

Pro-E General Functionality

General Functionality • Database management commands • Layer control for placing items on a layer and displaying layers • Measuring commands for distance, geometric information angle, clearance, and global interference on parts and assemblies • Viewing capabilities to pan, zoom, spin, shade, and re-orient models and drawings. The Function Modules of Pro/ENGINEER: The core of Pro/ENGINEER is the feature-based, parametric solid modeling system for modeling mechanical parts. The part model created by this system can be used to form mechanical assemblies and to produce engineering drawings. The model can also be used to carry out many other related analysis, simulation, planning and manufacturing activities such as the generation of CNC tool paths and Bills of Material. These extended functions are reflected by the following example Pro/ENGINEER modes. BASIC MODES Sketcher      :                   ...

Pro-ENGINEER

Image
                             An Overview of Pro/ENGINEER The Foundation of Pro/ENGINEER What is Pro/ENGINEER?                     Pro/ENGINEER is a computer graphics system for modeling various mechanical designs and for performing related design and manufacturing operations.                 The system uses a 3D solid modeling system as the core, and applies the feature-based, parametric modeling method.In short, Pro/ENGINEER is a feature-based, parametric solid modeling system with many extended design and manufacturing applications. How is Pro/ENGINEER different from other CAD systems?             Pro/ENGINEER was the first CAD system entirely based upon feature-based design and parametric modeling. Today most software producers have recognized the advantage of this approach an...
