In solid materials, residual stress is stresses that remain in them after their original cause of stress is removed. Residual stress can be useless and useful in a material. that is, it may be desirable or undesirable. Unintended residual stress in a material may cause it to fail prematu

Both metals and non-metals are very common materials that are widely used by humans. In fact, without these materials surviving would have been hard for us. They are different elements in the periodic table, which is why the topic needs to be treated for their clear differentiation. Tod

When we look everywhere around us, we must find plastics. They make lives easier, safer, cleaner, and even more enjoyable. They are term commonly used to describe a wide range of synthetic or semi-synthetic materials which is used in different applications. Plastics can be found in our h

There are various types of metals out-there suitable for specific applications. Even though metals are made by mining ore from within the earth. They are extracted out of rocks in a large-scale industrial process. Leaving that aside, our purpose here is to discuss the different types of

Over the year, maintenance became one of the most important factors an organization or industry must accomplish. The learning and performing maintenance is a very broad topic all technological organization must look into to keep organization and equipment in good working condition. The

As maintenance is essential in the industrial world, different types must be examined to ensure positive result achieved after the implementation. The different types of maintenance are used to increase the longevity or uptime of assets and utility of organizational facilities. In a prev

Spring of different types are common material seen in applications in our daily life. It is an elastic object that stores mechanical energy. It’s of different kinds, designs and are used for various purposes. The term which is often refers to coil springs. Conventional springs from resti

A hydraulic press is a machine press that generate compressive force by the use of a hydraulic cylinder. It is a device that is used for lifting heavyweight with the application of much smaller force. The hydraulic press was invented by Joseph Bramah in England. He accomplished the proje

Just as other machine tools, a forming press occurs to be one with its function of changing the shape of a workpiece. It often works with the application of pressure. Operators that operate this machine are called a press-tool setter or tool-setter. Machine press are available for differ

In the production and engineering world where machines are vastly used, a bearing is a mechanical component that is almost inevitable. The term is derived from the verb “to bear”. Bearings are found in all sorts of machines, but they mostly do their work in the subsurface. The mechanical

Originally, with the perfect design of gasoline internal combustion engines, if the spark plug is eliminated then the combustion process won’t work. The device delivers electric current from an ignition system to the combustion chamber of spark-ignition engines. Compressed fuel/air mixtu

Do you know without a starter motor an engine and its component won’t work? Well, you should know. A starter motor is one of the major component use in an internal combustion engine which is electrically powered. Because an engine cannot rotate on its own, a part is required to start the

Discovering the safety device used in most industry for pressure flow control, pressure relief valve it’s called. It’s an equipment that must be found in the industry to control an over-pressurized vessel. So, a pressure relief valve is a safety device designed to secure a pressurized sy

In one way of the other power must be transferred from one source of energy to another in a mechanical device, the most common and cheapest form is to use a belt and pulley. This power is either gotten from an electrical or mechanical generator to transfer a rotational motion to the appl

Rolling is carryout on a rolling mill and can be performed in two ways; hot and cold process. the rolling mill consists of two more working rollers, supporting rollers, roll stands, drive motor, flywheel, reducing gear, coupling gear etc. The rollers may be plain or grooved depending upo

Rolling is a common and compulsory process that is done in the manufacturing world for applications that involve the use of sheet metals. The rolling process is a metalworking process that helps to reduce the thickness of metal and make the thickness uniform. Today we’ll be looking at t

CNC is an abbreviation of Computer Numerically Controlled. It is a new feature widely available for machine tools like lathe, milling, drilling etc. to enhance their working ability and efficiency with the aid of a computer. Till date, the working of some these machines is manually opera

Rolling as one of the important processes in the engineering world, it is available in different types of a suitable specific operation. Like other manufacturing process defects also occurs in rolled products which are we have to discuss to them in order to prevent them. Today we’ll be

CNC machines are the actual machine where finished products are made. They are known for their high accuracy, working ease and automatic control. There are different machine tools that are CNC such as, drilling, lathe, milling etc. Today we’ll be looking at the working principle of CNC

Machine tools that feature CNC system contain some major parts and element that helps the effectiveness of the machine. Previously an article was published on control code one must know before using any CNC machine. We’ve examined two codes as G-code and M-code. Today we’ll be looking a
