7. HAL KORWA Avionics Division, Korwa of Hindustan Aeronautics Limited. Avionics Division Korwa was established in the year 1982. The Division of HAL, has been built in a pollution free environment sprawling over approximately 1 million sq.mts . of lush green area . The total covered area for manufacturing is around 38000 sq. mts Division has got a highly skilled work force of approximately 1100 including 200 highly qualified engineers.

9. SUKHOI-30 MKI

10. SUKHOI Su-30 MKI The Sukhoi Su-30MKI has been jointly-developed by Russia 's Sukhoi Corporation and India 's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). It is a heavy class, long-range air superiority fighter aircraft. The Su-30 MKI is more advanced than the basic Su-30MK , the Chinese Su-30 MKK , and the Malaysian Su-30 MKM . The aircraft features state of the art avionics developed by Russia, India , Israel , France and South Africa which includes display, navigation, targeting and electronic warfare systems. MKI stands for "Modernizirovannyi Kommercheskiy Indiski " meaning " Modernized Commercial India ".

11. GENERAL FEATURES OF Sukhoi 30 MKI Sukhoi 30 MKI is a 4.5 generation fighter aircraft . Fifth generation planes are yet to come. C ost of single Su-30 MKI is $ 35 million or Rs 1.61 billion As per deal between Russia’s Sukhoi Corporation and India’s HAL , in the first phase, components will be imported from R ussia and only assembling will be done in India. In the second phase , there will be transfer of technology from Russia to India , and then both manufacturing & assembling will be done in India. Various independent sources have claimed Su-30 MKI to be the most superior fighter plane in present World.

12. IFJ & EFJ It is the part of SU30-MKI IFJ means internal flexible joint EFJ means external flexible joint Cost 1 lakh after manufacturing

13. MANUFACTURING SHOP This shop manufacture various part of fighter plane and some part of Barmhos missile Present time ,manufacturing parts of Su30-MKI IFJ and EFJ are the part of SU30-MKI fighter plane EDM (electric discharge machine) is use for the IFJ and EFJ part

14. Localised extreme rise in temperature of 10,000 o C heat affected zone is limited to only 2 – 4 μm of the spark crater

15. Functions of the Dielectric are as follows: Insulation dielectric is to insulate the work piece from the electrode Ionization spark path must be de-ionized quickly Cooling spark has a temperature of 8,000-12,000° C when it punctures the work piece and so the dielectric must cool both the electrode and the work piece

16. ADVANTAGE EDM has no contact and no cutting force process, and therefore does not makes direct contact between tool electrode and the work material. This eliminates the chances of mechanical stress, chatter and vibration problems, as is prominent in traditional machining. No complicated fixtures are needed for holding the job. Material of any hardness can be cut. High accuracy and good surface finish are possible. Intricate-shaped cavities can be cut with modest tooling costs. Holes completed in one “pass” The EDM process is burr-free. Thin fragile sections such as webs or fins can be easily machined without deforming the part.

17. DISADVANTAGE Electrode wear takes place during the EDM operation when the electrode (i.e. the tool) gets eroded due to the sparking action. Limited to electrically conductive materials. Slow process, particularly if good surface finish and high accuracy are required Dielectric vapour can be dangerous. Tool life is limited. There is a possibility of taper and overcut in EDM.

18. CHARACTERISTICS OF EDM PARAMETERS VALUES Spark gap 0.005 mm - .125 mm Spark frequency 100-500 KHz Peak voltage across gap 30-250 V MRR 5000 mm3/min. Dielectric fluid EDM synthetic hydrocarbon Tool material Do not know ( maybe copper )

19. EDM WIRE CUT T hin metallic wire is fed on-to the work piece process can also cut plates as thick as 300mm used for making punches, tools and dies from hard metals guides are usually CNC-controlled deionized water is commonly used as the dielectric fluid diameter between 0.02 and 0.30 mm.

20. Subsystems of wire EDM Power supply. Dielectric system. Wire feeding system. Positioning system
