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. [...]

Vapor Absorption Vs Vapor Compression Refrigeration
There are some aspects in which vapor absorption refrigeration system is different from that of vapor compression. The main principle is the same for the two systems. But there are differences between power consumption COP, mechanical parts etc. Have a look Mechanical Engineering Interview Questions part – 1 Mechanical Engineering [...]
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 [...]
Limiting Friction Explained – Laws of Limiting Friction
a force acting on the opposite direction to the motion of the body is known as friction or force of friction. Friction can be of the following two types. Static Friction 2. Dynamic Friction The friction experienced by a body when at rest is known as static friction. The friction experienced by a body when at is known as dynamic friction. [...]
How does Plate and Frame Heat Exchanger Work
Different innovative heat exchangers are designed according to application. Various types of hardware arrangements and configurations are needed for the heat transfer equipment. Equipment are needed to be designed to match the hardware with the requirements. The double heat exchanger is the one which uses two concentric pipes of [...]
