To become familiar with some of the basic metal forming processes like extrusion, rolling, forging, wire drawing and sheet metal working
Understand the fundamental concepts of different metal forming processes their engineering applications and limitations.
Apply their knowledge to select suitable process, variables, tooling and machines/equipment to make the products from various metal forming processes.
Determine the forces and power requirement in different metal forming processes.
Investigate defects appeared in the products manufactured by various metal forming processes and determine their causes and remedies.
Identification of metal forming parameters such as friction, temperature, the resistance of the material etc, necessary for defect free products.
Forming Process also known as Metal Forming is a large set of manufacturing processes by which raw material is converted into a product. In this process, we apply stresses like tension, compression, shear, etc. to deformed the raw material. The example of forming processes are sheet metal manufacturing, forging, rolling, extrusion, wire drawing, and so on
Metal forming processes are an essential part of our society, and without them, our society would come to a grinding halt.
The products and components created by the different metal shaping techniques are used in creating everything from scaffolding and heavy machinery to designing and creating microprocessors and artificial intelligence.
When it comes to metal forming, there are several processes to choose from, with each offering its own list of benefits and detriments, each suited to certain applications, and each suited for different types of metal.
