Unconventional or nontraditional machining processes are used when one or more of the following occur: ... Electrical-Discharge Machining (EDM) is also called. 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. but this is also called non traditional machining. The present trend is the use of clear low viscosity fluids. <> Heat affected zone in EBM is less due to shorter pulse. By using the conventional machining the time taken for machining is more and the fewer surface finishes, as well as no accuracy. Keywords. 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. 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. For example, abrasive water jet operations use mechanical energy, but material is removed by erosion. Non-Traditional machining can also be called as _____ A) Contact Machining B) Non-contact machining C) Partial contact machining D) Half contact machining Answer: B. Conventional machining can be defined as a process using mechanical (motion) energy. 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 … In this, the metal removal rate is low and cannot be used for large machining cavities.

The process is environmentally friendly as it is noiseless without any chemical reactions and heating. stream The anode which is in the form of a beam attracts the electron beam and gradually gets accelerated.

From the mixing chamber, the mixture is supplied to the nozzle which is the high strength of a material i.e., tungsten carbide. The laser is man-made ruby crystal, containing chromium or Aluminium oxide. The most common electric fluid are minerals oil such as kerosene and distilled & deionised water is used in special applications. 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. non - traditional machining can also be called as : answer : option c : non - contact machining explanati view the full answer This site uses Akismet to reduce spam. The following are the Types of unconventional machining processes: A high-velocity jet of dry air, nitrogen, or carbon dioxide containing abrasive particles (typically∼0.025mm) is aimed at the workpiece surface under controlled conditions. 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. 7th May, 2014. So, fragile and brittle materials can also be processed. 2. A hole shape is affected by the depth of the workpiece. with [Pictures &... 12 Types of Spanners and Their Uses [with Pictures] PDF. A valuable amount of non-productive pump down period for attaining the desired vacuum. 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. 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 machining process is called non-traditional if its material removal mechanism is basically different than those in the traditional processes, i.e. • Ultrasonic Machining (USM) and Waterjet Machining (WJM) are typical examples of single action, mechanical non traditional machining processes. endobj In NTM processes, neither shearing occurs nor chips form.
