In fact, such processes don’t even utilize a so called cutting tool. • Very hard fragile materials difficult to clamp for traditional machining I The machining medium is solid grains suspended in an abrasive slurry in the former, while a uid is employed in the Jet machining process.  Very hard fragile materials difficult to clamp for traditional machining  When the workpiece is too flexible or slender  When the shape of the part is too complex PLAY. Subscribe to our newsletter to get notified when we upload new posts. Cite. Non-traditional machining is also called advance manufacturing process. MRR achieved in EDM process is enough lower than the MRR in case of the conventional machining process, so it cannot be taken as an alternative to conventional machining processes at all. With ever increasing demand for manufactured goods of hard alloys and metals, such as Inconel 718 or titanium, more interest has gravitated to non-conventional machining methods. 4 0 obj The EDM process can be used on any materials that are an electrical conductor. Electrically non-conducting materials cannot be processed by EDM. The beam is pulsed so that the released energy results in an impulse against the work surface that does melting and evaporation. Materials which cannot be machined by conventional methods are machined by LBM. Water Jet Machining (WJM) also called water jet cutting, is a non-traditional machining process in which high-velocity jet of water is used to remove materials from the surface of the workpiece. Nontraditional machining processes, also called advanced manufacturing processes, are employed where traditional machining processes are not feasible, satisfactory or economical due to special reasons as outlined below. EBM can provide holes of any shape by combining beam deflection using electromagnetic coils with high accuracy. Keywords. such as turning, drilling, shaping and milling. Initial cost and cost of the tool is very high, frequency tool replacement is required as a tool wear takes place in this operation. Special processing refers to those processing methods that are not in the traditional processing technology category. Nontraditional machining can be thought of as operations that do not use shear as their primary source of energy. It is suitable for both conducting and non-conducting materials. For example, abrasive water jet operations use mechanical energy, but material is removed by erosion. The electrical discharge machining is also called as electro-discharge or spark erosion machining based on the erosion of metal by spark discharges. Due to above reason, EDM replacing conventional machining. 1 0 obj Fine holes can be drilled easily and accurately. Several types of non-traditional machining processes have developed to better machining condition. Saif M. is a Mechanical Engineer by profession.

EBM provides very high drilling rates when small holes with large aspect ratio are to be drilled. This whole setup is fitted inside an enclosure, which carries good quality reflecting surface inside. We have also a Facebook community for you guys. Redressing of the tool is required for deep holes. The LDM setup consists of a laser tube, a pair of reflectors, one at each end of the tube, a flash tube or lamp, an amplification source, a power supply unit and a cooling system. Further since the machining unit (minimum controllable amount of material that can be removed) in EEM is 0.01 µm or less, it can be called atomic unit material processing. Non-Traditional Machining. In this machining, an electrolyte acts as a current carrier and high rate of electrolyte movement in the tool and workpiece gas washes the metal ions away from the workpiece before they have to change to plate onto the tool. In ultrasonic machining, ultrasonic waves are produced by means of magnetostrictive effects which is converted into mechanical vibration. Highly critical sections and weak materials can also be processed without any risk of their deformation because in this process applies direct pressure on the workpiece. endobj The velocity transformer which holds the tool firmly. It can machine almost any material irrespective of their mechanical properties. The present trend is the use of clear low viscosity fluids. electrodischarge or spark-erosion machining.

In this article, we will discuss what is unconventional machining process and its 9 Types of unconventional machining processes. The most common electric fluid are minerals oil such as kerosene and distilled & deionised water is used in special applications. As particle impact the work surface, they cause small cracks, and the gas stream carries both the abrasive particles and the fractured (wear) particles away. 2. The tool and workpiece should be chemically still with the electrolyte solution. Workpiece after machining is free any stress. Therefore by using unconventional machining the time taken is less and the surface finish and accuracy are excellent. There is no use of force, no direct contact between tool and workpiece. The unconventional machining it uses some form of energy for metal removal there is no direct contact between the tool and workpiece. An abrasive gun is used to supply an abrasive slurry, which is a mixture of abrasive grains and the water in between tool and workpiece interface under a pressure. Subsequently many non-traditional machining (NTM) or unconventional machining processes have emerged that to cater the need of market. Application of heat is focused, so rest of the workpiece is latest affected by the heat.

Conventional machining can be defined as a process using mechanical (motion) energy. Work holding and fixturing cost is very less because of the absence of mechanical cutting force. Types of Unconventional Machining Process, Advantages of the unconventional machining process, Disadvantages of the unconventional machining process, Mechanical energy based unconventional machining process, Chemical energy based unconventional machining, Thermo-electric energy based unconventional machining, What is TIG & MIG Welding: Difference Between TIG and MIG welding, What is Welding? The non-conventional machining process also called as the non-traditional machining process works on energies like mechanical, electrical, thermal, chemical, electrochemical and more. with [Pictures &... 12 Types of Spanners and Their Uses [with Pictures] PDF. Modification of this process are used for turning, slotting, trepanning, and profiling operation in which the electrode becomes the cutting tool. <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S>> Chemical energy based unconventional machining, The electrochemical-based unconventional machining process, Thermo-electric energy based unconventional machining. Very good accuracy and surface finish can be obtained. By using the conventional machining the time taken for machining is more and the fewer surface finishes, as well as no accuracy. If you want, you can join our community, here is the link to our Facebook group. In this process, a high velocity water jet is used to machining work piece. Extremely hard and brittle materials can be easily machined. The complex shape can be produced in the hard and brittle material. In this process the voltage between 50V and 980V and currents from 0.1A to 500A. %PDF-1.5 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. A valuable amount of non-productive pump down period for attaining the desired vacuum.
