What is conventional machining process?

What is conventional machining process?

What is Conventional Machining? The conventional machining process uses a human operator to direct and control machining tools such as milling, boring, and drilling machines as well as lathes and other sharp cutting tools.

Why unconventional machining process is needed?

The main reasons for choosing non-traditional machining processes are: To machine high steel alloys. To generate desired complex surfaces and. To achieve high accuracy and surface finish.

What is the difference between conventional machining and unconventional machining?

Conventional machining process involves the direct contact of tool and work piece, whereas unconventional machining does not require the direct contact of tool and work piece. Conventional machining process has lower accuracy and surface finish while non-conventional machining has higher accuracy and surface finish.

What is non-conventional machine?

The non-conventional machines employ the modern and latest technology in processing. In these machining methods, no direct contact between the machine tools and the workpiece. The tools used are infrared beam, laser beam, electric arc, plasma cutting, and electric beam.

What is the difference between conventional and non-conventional machining process?

What are the advantages and disadvantages of ECM?

Advantages and Disadvantages:

• It can machine very complicated surface.
• A single tool can be used to machining large number of work-piece. Theoretically no tool wear occur.
• Machining of metal is independent on strength and hardness of tool.
• ECM gives very high surface finish.

What are the advantages of ECM process?

Advantages of electrochemical machining:

• The rate of machining does not depend on the hardness of the work piece material.
• The tool does not wear.
• No stresses are produced on the work piece surface.
• No burrs form in the machining operation.
• High surface quality may be achieved.
• High accuracy of the machining operation.

What is conventional and non conventional machining?

Conventional machining process involves the direct contact of tool and work piece, whereas unconventional machining does not require the direct contact of tool and work piece.

What is non conventional?

Definition of nonconventional : not conventional : not conforming to convention, custom, tradition, or usual practice : unconventional nonconventional teaching methods nonconventional energy sources Ten years ago, the alternative press was hard to find but easy to define.

What are limitations of ECM process?

Disadvantages and Limitations of ECM Process: (i) All non-conducting materials cannot be machined. (ii) Total material and workpiece material should be chemically stable with the electrolyte solution. (iii) Designing and making tool is difficult but its life is long so recommended only for mass production.

Which of the following material Cannot be machined using a ECM?

7. Which of the following materials can be machined using ECM? Explanation: Hard conductive materials can be machined and nonconductive materials cannot be machined using ECM.

What is unconventional machining explain electrochemical machining?

Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials.

What are the classification of unconventional machining processes?

Classification of unconventional machining processes was mainly on the basis of the nature of energy employed in machining process. They are 1. Chemical Processes 2. Electrochemical Processes

What are the advantages of non-conducting machining tools?

There is no use of force, no direct contact between tool and workpiece. No use of heat, so mechanical and thermal remaining stresses are absent in the workpiece. Very close tolerances can be obtained. All non-conducting materials cannot be machined.

What is the process which removes minimum material?

The processes which remove minimum material are Electron beam machining. 10. What is the unconventional process which consumes maximum power? The process which consumes maximum power is laser beam machining.

What are the limitations of traditional machining methods?

•Traditional machining methods are often ineffective in machining hard materials like ceramics and composites or machining under very tight tolerances as in micromachined components. •The need to a avoid surface damage that often accompanies the stresses created by conventional machining.
