What is non conventional machine?
An unconventional machining process (or non-traditional machining process) is a special type of machining process in which there is no direct contact between the tool and the workpiece. In unconventional machining, a form of energy is used to remove unwanted material from a given workpiece.
Which is an unconventional process of machining?
Abrasive jet machining is a mechanical energy based unconventional machining process mostly used in the machining of hard metals.
What is need of non-conventional machining?
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.
Which is are the examples of non-conventional machining methods?
Ultrasonic Machining (USM) and Waterjet Machining (WJM) are typical examples of single action, mechanical non traditional machining processes. The machining medium is solid grains suspended in an abrasive slurry in the former, while a fluid is employed in the WJM process.
What is non conventional process?
Non-traditional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical, thermal, electrical or chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes.
What is conventional and non-conventional machining?
Conventional machining can be defined as a process using mechanical energy. Non-conventional machining utilises other forms of energy. The three main forms of energy used in non-conventional machining are thermal, chemical and electrical energy. Examples.
What are the different energy sources used in nonconventional machining processes?
Energy sources for non traditional machining techniques are Electrical , mechanical,thermal, chemical energy, hydraulic as in case of water jet or combinations of these energies .
What are the applications of WJM?
WJM process has many applications in different area of surface engineering such as cleaning of unwanted coating for surface preparation, cleaning of food utensils, cleaning of rust and residues, polishing, decorative finishing and surface texturing on both metals and non-metals, etc.
What are non conventional processes?
Non-conventional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving Mechanical, Thermal, Electrical or Chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes …
What is the difference between conventional and non conventional machining process?
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 the difference between conventional and unconventional machining?
Is CNC non conventional?
Machining can be described as conventional, which requires manual technician prompting and manipulation of the cutting tools, or non-conventional, such as CNC machining, which relies on computer automation to drive the process.
What is the difference between conventional and nonconventional machining?
What is non-conventional method?
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 is the principle of WJM?
Working of Water Jet Machining (WJM): Water from the reservoir is pumped to the intensifier using a hydraulic pump. The intensifier increases the pressure of the water to the required level. Usually, the water is pressurized to 200 to 400 MPa. Pressurized water is then sent to the accumulator.
What are the advantages of WJM?
It has low operating and maintenance cost because it has no moving parts. The thermal damage to the workpiece is negligible due to no heat generation. It is capable of cutting softer materials (WJM) like rubber, plastics or wood as well as harder material (AWJM) like granite.
What is conventional and nonconventional 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 conventional machining?
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.
What is the meaning of non conventional machining?
Non-traditional machining, also known as “non-conventional machining” or “modern machining method”, generally refers to the machining method of removing or adding materials with energy of electricity, heat energy, light energy, electrochemical energy, chemical energy, sound energy and special mechanical energy, so as to realize materials being
What is traditional machining process?
In these “traditional” or “conventional” machining processes, machine tools, such as lathes, milling machines, drill presses, or others, are used with a sharp cutting tool to remove material to achieve a desired geometry.
How many types of non-traditional machining techniques are there?
In this article, we listed the 9 types of non-traditional machining techniques. I believe it can be the handbook for most of you who want to learn the non-traditional machining process, advantages, classifications etc.
What is the difference between conventional machining and chip type machining?
In conventional machining, the cutting tool must be hard from the workpiece then cutting will occur. conventional machining chip formation will occur and chip type is macroscopic type chip is formed.
