21 Difference Between Conventional and Unconventional Machining Process

Hello, friends Today we are going to discuss what is difference between conventional and unconventional machining processes.

Before knowing the difference between conventional and unconventional machining processes first of all we have to know what is conventional and unconventional machining processes.

So without wasting any time let's get started.

What is the Conventional Machining Process?

The conventional machining process is a process in which a human operator operates the machine manually by hand such as lathe machine, drilling machine, milling machine, slotting machine, shaper machine, planer machine, etc.

This machining process is also called as traditional machining process.

What is the Unconventional Machining Process?

The unconventional machining process is a process that uses less human effort, usually a fully automated machining process.

Such as abrasive jet machining, water jet machining, ultrasonic machining, etc.

This machining process is also called a non-traditional or non-conventional machining process.

Conventional Vs Unconventional

What is the Difference Between Conventional and Unconventional Machining Processes?

There are the following 21 common differences between conventional and unconventional machining processes.

Conventional Machining Process	Unconventional Machining Process
Example of the conventional machining process is lathe machine, drilling machine, milling machine, etc.	Examples of the unconventional machining process are abrasive jet machining, ultrasonic machining, water jet machining, electrical discharge machining, etc.
The cutting tool and the workpiece are always in physical contact with each other in relative motion.	There is no physical contact between the tool and the workpiece.
The cutting tool will be always harder than the workpiece.	The cutting tool need not be harder than the workpiece it is used non-traditional techniques like laser beams, electric arcs, etc.
Due to excessive wear, the life of the tool is shortened.	Tool life is longer.
Generally, it is operated by hand.	Generally, it is a fully automated process.
Usually, the cutting material comes out in small pieces in the form of a chip.	Generally, the cutting material comes out in small pieces in chip form or in powder form.
In this conventional machining process, force is required to cut the material.	It uses different energy like electricity, thermochemistry, etc. to provide machining action.
It is suitable for all materials.	It is not suitable for all materials.
It has low accuracy and surface finishing.	It has good accuracy and surface finishing.
It has more noise pollution.	It has less noise pollution.
It costs less.	It has a higher cost.
Requires both skilled and non-skilled operators.	Requires skilled operator.
Easy setup of equipment.	Complex setup of equipment.
It can not be used to produce prototype parts very effectively.	It has the capacity to produce prototype parts very effectively.
The energy used to remove the material is primarily mechanical.	Energy is mainly used mechanical, electrical, thermal, and chemical.
Macroscopic chip formation.	Microscopic chip formation.
Hard materials like ceramic-titanium cannot be machined.	Harder materials can be machined.
The mechanism of material removal is shearing.	The system is based on the energy used.
This machining process can be used for mass production.	Can not be used for mass production.
Production cost is low.	Production cost is high.
MMR is high.	MMR is low.

So friends here I discussed 21 common differences between conventional and unconventional machining processes.
