The high cost of the equipment and necessary regular maintenance applicable to any equipment using the vacuum system. A person who specializes in machining is called a machinist.A room, building, or company where machining is done is called a machine shop.Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are … So the newer machining processes developed are often called"Non Traditional machining process " or "Unconventional machining process".In this employs some form of energy like mechanical chemical thermal electro chemical etc.for cutting the material. This whole setup is fitted inside an enclosure, which carries good quality reflecting surface inside. <> Mechanical Machining I Jet Machining and Ultrasonic Machining (USM) are typical examples of single action, mechanical non traditional machining processes. The electrolyte is a highly conductive inorganic salt solution, such as sodium chloride mixed with water or sodium nitrate. Special processing is a new process developed in recent decades. In this process, high velocity water jet strikes at working surface and metal removed due to erosion by water particle. electrodischarge or spark-erosion machining. These materials are widely used in the field of the nuclear industry, space research, missile technology and in other industries which requires high strength to weight ratio, heat-resisting quality, hardness and toughness. It is the reverse of electroplating. No use of heat, so mechanical and thermal remaining stresses are absent in the workpiece. From the mixing chamber, the mixture is supplied to the nozzle which is the high strength of a material i.e., tungsten carbide. Also the selection process becomes more important as all the machining processes cannot be done by using a single method we need to choose an efficient method for different machining processes. a different form of energy (other than the excessive forces exercised by a tool, which is in physical If you like our article then please share it with your friends. which were presented in this article in a detailed way. The adequate form of the high value of MRR can be achieved as compared to other non-conventional machining processes. Special processing refers to those processing methods that are not in the traditional processing technology category. ... includes torch cutting, electrical discharge machining or EDM, and high-energy beam machining. Non-Traditional Machining Method is an advanced method used to overcome the problems of Traditional Machining methods. Ability to cut the heat sensitive materials. Subsequently many non-traditional machining (NTM) or unconventional machining processes have emerged that to cater the need of market. Non-Traditional machining can also be called as _____ a) Contact Machining b) Non-contact machining c) Partial contact machining d) Half contact machining View Answer. Non-Traditional Machining. In this, the metal removal rate is low and cannot be used for large machining cavities. In ultrasonic machining, ultrasonic waves are produced by means of magnetostrictive effects which is converted into mechanical vibration. 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. 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. Electro Chemical Grinding (ECG) Electro chemical grinding is also called electrolytic grinding. Save my name, email, and website in this browser for the next time I comment. It is mostly used to machining soft materials. endobj Extremely hard and brittle materials can be easily machined. This process not suitable for mass production because of the high maintenance requirement. [Short and Complete Guide], Heat Treatment Processes: Types, Methods, Procedure, Applications (PDF), What is Shaper Machine and The 4 Major Types of Shaper Machines, Cams and Followers: How they Work? It is pumped at a high rate through the passage in the tool. 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. Non traditional 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.
