Manufacturing Technology – II MI 232 Instructor – Inderdeep Singh Spring 2011-2012 Foundry - Factory that produces metal castings • Casting: Process in which molten metal flows by gravity or other force into a mold where it solidifies in the shape of the mold cavity Steps: 1. Melt the material (metal) 2. Pour it into a mold 3. Let it freeze Refractory mold pour liquid metal solidify‚ remove finish Capabilities and Advantages • Versatile: complex geometry‚ internal cavities

Corrosion can also refer to other materials than metals‚ such as ceramics or polymers‚ although in this context‚ the term degradation is more common. In other words‚ corrosion is the wearing away of metals due to a chemical reaction. Many structural alloys corrode merely from exposure to moisture in the air‚ but the process can be strongly affected by exposure to certain substances (see below). Corrosion can be concentrated locally to form a pit or crack‚ or it can extend across a wide area more or

This chapter will explore more on the design procedure of a prosthetic leg and the calculations that come into play in this procedure. The design will be based on the parameters and function of a normal leg and also on the current available prosthetic legs. In prosthetic leg calculations‚ the main factors to consider are the kinematics‚ kinetics and the energetics. Kinetic quantities are computed by first measuring the external forces acting on the body. For normal walking‚ the external forces are

Welding is a method for the permanent assembly of metal parts. Arc welding can be divided at least three classes: arc welding‚ gas welding‚ and resistance welding. 1) Arc welding: Heat is generated by an electric arc and the parts are simply fused together and became one. In some cases electrode is used that provides a filler material. 2) Gas welding: The burning gas (oxygen and acetylene) raises the temperature of the part to be joined and a welding rod provides filler material. 3) Resistance

P4: “Plan the tools and equipment needed to produce welded components safely using a selected welding process” What is MIG welding? MIG welding which stands for Metal Inert Gas‚ also known as Gas Metal Arc Welding (GMAW) is a welding process in which an electric arc forms between the wire electrode and the metal work piece. This then heats the metal work piece as well‚ causing them to melt and join together. Along with the wire electrode a protective gas called shielding gas is fed through the welding
