Answer. This leakage of... Slotter Machine - Types, Parts, Operations, Diagram, Specification. ECM is capable of machining metals and alloys irrespective of their strength and hardness 2. In Conventional machining because of scrap and chip formation more wastage of material. Similarly, Abrasive Jet Machining (AJM), Ultrasonic Machining (USM), Water Jet and Abrasive Water Jet Machining (WJM and AWJM), Electro-discharge Machining (EDM) are some of the Non-Traditional Machining (NTM) Processes. Material removal takes place due to the application of cutting forces – energy domain can be classified as mechanical, 4. Following reactions takes place while machining of pure iron through ECM using NaCl+H2O as electrolyte. 15. Material removal may occur with chip formation or even no chip formation may take place. Ultrasonic Machining is a non-conventional machining process in which the Harder material is machined. Mechanical: Erosion of the work material by a high velocity stream of Water jet machining process is more versatile and can be used for the metal as well as non metal. Noisy operations mostly cause sound pollutions. The unconventional machining is also called as non-traditional machining. Non-conventional tools have complex setup and hence requires a skillful operation by expert workers, whereas conventional tools do not require any special expert for its operation and are quite simple in the set-up. In order to … Thanks for contribution ,these processes can be achieved some operations which difficult by conventional machining . a) boring b) milling c) tumbling d) rolling Q10. When it comes to creating non-conventional and conventional parts through metal cutting and other machining processes, there are two kinds of machining process available. Spare parts of conventional machines are easily available but not for non-conventional machines. The unconventional machining use for the machine the hard and brittle materials such as carbides, stainless steel, Hastelloy, nitralloy, waspalloy, and any other that cannot be machined by a conventional process using the conventional machines such as lathe, milling, shaper, planer etc. No noise pollution is created as a result of non-conventional methods as these tools are much quieter. and also see the types, advantages, disadvantages and applications of the Machining Process. 15. [3] Laser beams can be paired with gases to help the cutting process be more efficient, help minimize oxidization of surfaces, and/or keep the workpiece surface free from melted or vaporized material. There are different setup for this process. Machining is one of the most important process of metal forming and shaping. The former ones provide basic shape and size to the material as per the designer’s requirement. 1. In the ElectroChemical Machining process, there is the tool and work piece. Conventional and Non-Conventional machining processes are divided according to contact between tool and work material.

Your email address will not be published. They are: The conventional machining process involved tool wearing as there is physical contact between the tool and the work piece. link to Hydraulic seals - Definition, Types, Diagram , Function, Failure, Application, link to Slotter Machine - Types, Parts, Operations, Diagram, Specification. Tool life is less due to high surface contact and wear. 13. WJ machining is a non-conventional machining process in which a high-speed jet of water is used as the tool to remove the workpiece material by erosion. Today we will learn about Non-traditional machining processes requirement, types, advantages and disadvantages. The following are the characteristic of a NON-CONVENTIONAL machining, EXCEPT..... Q. Generally macroscopic chip formation by shear deformation. 14. UN CONVENTIONAL MACHINING PROCESSES (Mechanical Engineering) Time: 3 hours Max. It is necessary to have some exposure to the actual machining operations and their analyses. Generally, they are manual to operate. Electrically conductive parts irrespective of their hardness, shape and toughness can be machined by EDM since the material removal rate is related to the melting point of the metal to be machined. Turning and Boring 3. (b). Not Suitable for every type of material economically. 9. In the non-conventional process, this is not the case. EDM uses electrical energy to generate electrical spark which travels through a dielectric fluid at a controlled distance. 7) Which of the following statements are true for Electro-Chemical Machining (ECM)? Introduction to Seals : Various similarities and differences between conventional machining and non-traditional machining (NTM) processes are given below in table format. Answer: d Explanation: WJM stands for water jet machining and it is an unconventional process of machining. Material removal processes once again can be divided into mainly two groups and they are “Conventional Machining Processes” and “Non-Traditional Manufacturing Processes”. The conventional machining process involved tool wearing as there is physical contact between the tool and the work piece. 13. non-conventional machining process which is defined as the process in which materials are removed from the workpiece in most accurate and effective manner. Secondary manufacturing processes provide the final shape and size with tighter control on the dimension, surface characteristics, etc. Classification of Non-Traditional Machining These can be classified according to the source of energy used to generate such a machining action: mechanical, thermal, chemical and electrochemical. Drilling and 4. 1 Which of the following processes use mechanical energy as the principal energy source (three correct answers): (a) electrochemical grinding, (b) laser beam machining, (c) conventional milling, (d) ultrasonic machining, (e) water Conventional machining involves the direct contact of tool and workpiece. ECM Process Parameter: Voltage: 4 to 30 V Current: 50 to 40000 A MRR: 1600 mm3/min Surface 26. Whereas unconventional machining does not require direct contact of tool and workpiece. The machining provided by laser beams is high precision, and most of these processes do not require additional finishing. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. Non-conventional tools are very expensive than conventional tools. Cutting tool not harder than work piece, 4. Materials are removed Non-conventional tools are more accurate and precise than the conventional tool. Conventional machining vs. non conventional machining 1. Non-traditional machining is also called advance manufacturing process. Material removal processes are mainly secondary manufacturing processes. CONVENTIONAL MACHINING PROCESSES AND MACHINE TOOLS Module-IV Turning Turning operation is a machining process and is used to produce round parts in shape by a single point cutting tool. No cutting forces are involved in ECM process 3. 2. Electro Discharge Machining (EDM) is an electro-thermal and non-conventional machining process, where material is removed due to thermal energy of the spark. Manufacturing processes can be broadly divided into two groups and they are primary manufacturing processes and secondary manufacturing processes. conventional machining. Milling. Hydraulic seals - Definition, Types, Diagram , Function, Failure, Application. Before going down to the machining process, we need to know about some terms, and they are as follows. In which type of metal removal process, grinding is included? Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. a) conventional machining b) abrasive process Several types of non-traditional machining processes have developed to better machining condition. Since oil is a liquid it has the tendency to 'leak' through every gas/slot it finds during movement. Required fields are marked *. Generally, they are a fully automated processes. 14. Non Conventional machines can handle very complex jobs as compare to Conventional machining. Shaping and Planning 2. ASWDC (App, Software & Website Development Center) Darshan INTRODUCTION:Manufacturing processes can be broadly divided into two groups and they are primarymanufacturing processes and secondary manufacturing processes.
