Machining processes that are unconventional: types, workings, uses
INTRODUCTION:
Hello friends, Today we will cover all aspects related to unconventional machining process like their types, parts, working procedure, application, advantages, disadvantages, etc.
Unconventional machining processes are widely used where a lot of hard and brittle materials are found such as tungsten carbide, high speed steels, stainless steels, ceramics, etc. Which can not be processed by the conventional machining process.
Most of the conventional machining processes like lathe machines, planer machines, milling machines, drilling machines, slotting machines, shaper machines, etc. Already covered in the previous post.
Here we will only know about the unconventional machining process.
So, without wasting time let's get started
What is Unconventional Machining Process?
An unconventional machining process is a very special type of machining process because in this process there is no direct contact between the tool and the workpiece.
In an unconventional machining process, a form of energy (such as mechanical energy, electrical energy, chemical energy, etc.) is used to remove unwanted material from a given workpiece.
For supporting the workpiece in these types of machining processes always fixtures are used.
It is also called a non-traditional machining process or non-conventional machining process.
So, If I continue to pronounce these names, then don't get confused.
Advantages of unconventional machining process :
- It has good accuracy.
- It provides a good surface.
- Complex shapes can be made easily.
- It has longer tool life.
- The rate of metal removal is high.
Disadvantage of unconventional machining process:
- The cost of this process is high.
- It requires skilled operators.
- Its setup is difficult.
Classification of Unconventional Machining Process:
Different types of energy are used in this machining process to remove metal.
- Because of which on the basis of energy use
- the unconventional machining process can be classified into four categories:
- Mechanical Energy Based
- Electrical Energy-Based
- Chemical and Electrochemical Energy Based
- Thermal Energy-Based
Mechanical Energy Based:
In this process, mechanical energy is used to remove unwanted materials like abrasive jet machining, water jet machining, ultrasonic machining, etc.
Electrical Energy-Based:
In this process, an electrical spark is used to remove unwanted material like electrical discharge machining, wire cut electrical discharge machining, etc.
Chemical and Electrochemical Energy Based:
In this machining process, chemical energy is used to remove unwanted materials like photochemical machining, electrochemical machining, electrochemical grinding, etc.
Thermal Energy-Based:
In this machining, process heat is used to remove unwanted material like plasma beam machining, laser beam machining, etc.
Types of Unconventional Machining Process:
Some of the common types of unconventional machining processes are discussed which are used for machining using different energy sources:
- Abrasive Jet Machining
- Ultrasonic Machining
- Electrochemical Machining (ECM)
- Electrical Discharge Machining (EDM)
- Electron Beam Machining
- Laser Beam Machining
- Electrochemical Grinding
