Hello learners, today in this paper we are going to discuss What is Machining Process? and also see the types, advantages, disadvantages and applications of the Machining Process.
Before going down to the machining process, we need to know about some terms, and they are as follows.
A machine tool is a power-driven device used for sizing, shaping, and processing of a product to the desired accuracy by removing the excess material in the form of chips.
For example, Lathe Machine, Drilling Machine, Shaping Machine, Planar Machine etc.
A cutting tool is used to remove the material from the surface of the workpiece. It must be harder than the workpiece to carry out the operation.
There are two types of cutting tools.
The unwanted material removed from the surface of the workpiece due to the application of load upon the cutting tool called as Chips.
There are two types of chips.
The Discontinuous chips are simply thrown away from the work zone during machining.
The Continuous chips may get adhered or welded onto the rake face of the tool due to the high temperature called as Built Up Edge formation(BUE).
Now let's dive into our main topic that is Machining Process.
It is a process in which a piece of raw material is cut into a desired shape and size using sharp cutting tools called a Machining Process.
There are two types of the machining process.
The Conventional machining processes are as follows.
It uses a multi-point cutting tool also known as a Drill bit, to remove the material from the surface of the workpiece in the form of holes.
The MRR (Material Removal Rate) is very high in the case of the Drilling operation, compared to the working on the single-point cutting tool.
The parts of a Drilling machine are Table Clamp, Vertical Column, Base, Swivel Table, Power Transmission system (Stepped Cone Pulley), Drill Feed Handle (Hand Wheel), Spindle, Chuck, and Drillbit.

It is an advancement of Drilling operation i.e. Enlarging an existing hole is called boring operation.
Milling is an operation that uses rotory cutters such that it can advances into the work material.
To make grooves on the work material, milling operation can be performed.
It is an operation performed on the lathe machine which is used to remove the material from the surface of the workpiece such that the diameter of the component reduces to the desired value called Turning operation.
An advanced to Conventional Machining processes.
It is one of the types of unconventional Machining methods that can produce Circular and non-Circular holes of a very small size which is <1mm size.
This tool will induce impact loads on to the abrasive particles which in turn induces impact loads on to the workpiece and thereby the machining can be done.
It is also known as Spark Machining process.
In this process, electrical energy is used to generate the Spark between the tool and workpiece submerged under the dielectric medium so that material removal takes place from the surface of the workpiece by the local melting or the vaporization.
