Non traditional machining
More power required for machining. Google Scholar  Umehara N Magnetic fluid grinding — A new technique for finish advanced ceramics.
It is not economical for bulk production. In aero-space requirement of High strength at elevated temperature with light weight led to development and use of hard titanium alloys, nimonic alloys, and other HSTR alloys.

The narrow cutting stream and computer controlled movement enables this process to produce parts accurately and efficiently. Figure: Laser beam machining schematic Dept. It is mostly used to machining soft materials. It is no longer possible to use conventional process to machine these alloys. In this process, high velocity water jet strikes at working surface and metal removed due to erosion by water particle. A current of electrolyte fluid carries away the deplated material before it has a chance to reach the machining tool. Low material removal rate. In aerospace industries, parts such as titanium bodies for military aircrafts, engine components aluminium, titanium, heat resistant alloys , aluminium body parts and interior cabin parts are made using abrasive water jet cutting. This heat energy use to remove metal by melting and evaporation of metal particles. The metal is removed by melting and evaporation of metal particle from contact surface. For machining hard surface through conventional machining, we required a harder tool material which is sometime uneconomical and sometimes unavailable. After that limit, MRR remains constant to some extent and then decreases. It can be easily automated. Laser Beam Machining Process: This machining process uses laser or light energy for metal removal.
The carrier gas Dept. The high velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet.
These abrasive particles increase the cutting ability of water and can be used to cut hard material. Abrasive Jet Machining Process: In this machining process, a high stream of abrasive particles forced towards work piece, this will remove metal from striking surface due to erosion.
Only finishing operation should be done in this process as MRR for this process is low.
Application of non traditional machining
These abrasive particles increase the cutting ability of water and can be used to cut hard material. Ann CIRP 33 1 : — It is no longer possible to use conventional process to machine these alloys. This high concentrated electron beam strikes at working surface and produce heat energy. This heat energy use to remove metal by melting and evaporation of metal particles. This slag is removed from electrolyte by some cleaning system. High metal removal rate. It can provide up to 50 kW power in pulsed mode and 1 kW in continuous-wave mode. Work piece is too slender and flexible to clamp. Figure shows a typical magnetostrictive transducer along with horn. This electron beam generated by an electron gun and travels through the magnetic lenses, electromagnetic lens, defection coil and finally impinges on the working surface. Mach Sci Technol — We have lasers that are capable of removing oxide layers, paints and coatings from metals.
This machining process is especially ideal for cutting materials that cannot be cut by laser or thermal cut. Related Post. There are many disadvantages and limitations of conventional machining like tool wear, cannot machining complex surface efficiently, gives lower surface finish etc.
