Forming and Generating Method in Lathe Machine Operations
Raw materials of irregular size and shape has very little value. So to impart some function ability in the raw material we have to add some values to it. By production or manufacturing process an irregular shaped work piece is converted into a high utility product. This finished product has desired size, shape and meets our requirement. [...]

Types of Chips in Machining
Conventional machining operation always produces some chips. The nature of the chips depend on operation properties of the workpiece material cutting environment The cutting tool has to overcome the resistance of the work material to give it a desired shape. So cutting tool must be more harder, wear resistance than the w/p. The main [...]
Electron Beam Machining (EBM) Principles
The source of energy in electron beam machining is high-velocity electrons, which strikes the surface of the workpiece and generate heat. Electrons escape from the hot surface and a voltage of 50 to 200 kV helps to accelerate them. These high energy electrons possess high energy density generally in the order of 10ˆ4 kW/mm². Thin and [...]
Ten Tools Every Welder Wants
This article is all about the tools that welders want to have in their shop. They make welding easier, and in many cases, they make the welding process — from start to cleanup — more enjoyable. If you’re new to welding and you have a birthday coming up, you’re going to want to start dropping hints about these tools to your family. As [...]
Laser Beam Machining (LBM) Principles and Applications
As the name implies in Laser beam Machining the source of energy is the LASER (Light Amplification by Simulated Emission of Radiation). The laser beam focuses optical energy on the surface of the workpiece. A laser beam can be so powerful when used with a lens system that it can melt and vaporize diamond as the energy density can be of [...]
