What are cutting fluids? Cutting fluids are the fluids which are generally applied while the machining (or cutting) operation is taking place. The machining operation can be any i.e. milling, turning, drilling etc. Sometimes a cutting fluid is also referred as coolant but it is wrong. A cutting fluid performs several functions and cooling the… Read More »
What is a material removal process? Material removal process is a type of manufacturing process in which the final product is obtained by removing excess metal from the stock. The best example of a machining process is generating a cylindrical surface from a metal stock with the help of a lathe. This is one of… Read More »
What is powder metallurgy? Powder metallurgy is a kind of manufacturing process in which we make final products with the help of powdered metal. In this process we heat powdered metal to a temperature below its melting point and then compact that metal to a desired shape. Since the powdered metal gets compacted it its… Read More »
Cast iron is a ferrous alloy which has more than 2% carbon in it. Though it can have any percentage of carbon between 2% to 6.67%, but practically it is in between 2% to 4% only. It has got its name due to its excellent casting qualities. It is hard and brittle. There is a… Read More »
What is extrusion? Extrusion is a type of forming process (which is a type of manufacturing process) in which a metal is confined in a closed cavity and then allowed to flow through only one opening so that the metal takes the shape of opening. This process is exactly same as squeezing toothpaste out of… Read More »
What is forging? Forging is a manufacturing process in which shape of a heated metal changed by applying external force. Heated metal is used in forging because it is much easy to reshape heated material compared to colder one. However, in many forging operations cold metal is also used. Forging operations There are basically two… Read More »
What is casting? Casting is a manufacturing process in which molten metal is poured into a specially designed cavity. When metal cools down and becomes solid, it takes the shape of cavity. This cooled solid metal is called casting. After this we take out that casting of desired shape and size from the cavity. We… Read More »
What is a manufacturing process? It can be defined as Manufacturing is the process of converting raw materials into finished goods The branch of engineering which deals with the manufacturing is known as manufacturing engineering (or science). Manufacturing is also taught as a subject in Mechanical engineering. There are many types of manufacturing processes but… Read More »
What is a lathe? A lathe is probably one of the oldest machine tool invented by human beings. It is generally used to generate cylindrical surfaces but many different kinds of surfaces can also be generated by them. A lathe is a simple to use machine tool and has different types (according to use) Types… Read More »
There are basically two types of reciprocating internal combustion engines on the basis of working Four stroke engines Two stroke engines (sometimes also referred as two cycle engine and 2 stroke engine) If you want to understand two stroke engines completely we recommend you to also read four stroke engines. Let us continue with our… Read More »
