Conventional machining process: Definition, Advantages, Limitations [with Pdf]

Before knowing about conventional machining, let’s see the meaning of machining.

What is Machining?

Machining is a metal removing process. It removes a material & decreases the material’s mass hence this is a subtractive process.

Conventional machining process

What is Conventional machining process:

1] Conventional Machining process is a machining process in which the machining carry out with the traditional method means not using any advanced method for the machining. Therefore this machining process is also called as traditional machining process.

2] In this process the sharp point cutting tools are used for the machining purpose, such as the taper tool in the lathe machine for tapering.

3] The cutting tool material is harder than the work-piece material & the cutting tool is in directly contact with the workpiece hence more tool wear occurs.

4] The cutting tool is used against rotary or stationary work-piece for the material removal.

Examples of conventional machining process:

  1. Lathe machine
  2. Milling machine
  3. Vertical drilling machine  
  4. Grinding machine

Advantages of conventional machining process:

  1. Different materials can machined.
  2. Easy setup of the equipment’s.
  3. Less capital cost.

Disadvantages / Limitations of conventional machining process:

  1. Less surface finish.
  2. They can’t machined complex shapes.
  3. More tool wear.
  4. Lower dimensional accuracy.
  5. Noisy operation causes sound pollution.

Applications of conventional machining process:

  • Drilling holes in workpiece using drill machine.
  • Knurling, Turning, Facing operations on lathe machine.

Difference between traditional and non traditional machining process:

Sr. No.Conventional or Traditional machiningNon conventional or Non traditional machining
1A poor surface finish is obtained.A better surface finish is obtained.
2It can’t be used for small-size machining.It can be used for small-size machining.
3The problem of tool wear, hence tool life is less.Here is problem of the tool wear, therefore life of tool is more.
4Less investment or capital cost.More capital or investment cost.
5Direct contact between tool and workpiece.No direct contact between the tool and workpiece.
6It can’t make microholes.It can make micro holes.
