Electro chemical machining

  1. 1. ELECTRO CHEMICAL MACHINING [ECM] SUBJECT : MANUFACTURING ENGINEERING - 3 PREPARED BY : JAYKUMAR R. SONAR ENROLL. NO : 149740319047 GUIDED BY : MR. D . T . PATEL
  2. 2. OUTLINE  Definition Of Topic  Aims Of Usage  History  Basic Working Principle  Tools Of System  Advantages And Disadvantages  Applications  Economics  Products
  3. 3.  WHAT IS ECM ?  Electrochemical Machining (ECM) Is a Method of Removing Metal Particles by an Electro- Chemical Process Instead of Standard Machining Methods .  It Gives a New Perspective To Machining Process And Being An Initiator Of New Technologies .
  4. 4.  AIM OF USAGE  To Process Complex Materials Which Standard Machining Methods Are Insufficient .  Also For Processing Extremely Hard And Brittle Materials With High Sensitivity .
  5. 5.  HISTORY  The First Introduction Of ECM Was In 1929 By Gusseff , Its Industrial Applications Have Been Extended To Electro-Chemical Drilling , Electro-chemical Deburring , Electro-Chemical Grinding And Electro-Chemical Polishing .  The Techniques Was Applied In Several Ways . And As A Machining Technique In The 60’s & 70’s.
  6. 6.  WORKING PRINCIPLE  As The Tool Approaches The Work Piece It Erodes The Negative Shape Of It. Thus Complex Shapes Are Made From Soft Copper Metal And Used To Produce Negative Duplicates Of It. • Anode Reaction Fe  Fe++ + 2e • Cathode Reaction 2H2O + 2e  H2 + 2OH-

  8. 8.  MADE BY ELECTROCHEMICAL MACHINING ( ECM )
  9. 9.  In ECM , Cathode parts Must Design Specially To Machining Work piece.
  10. 10.  TOOL OF ECM SYSTEM  The Power Supply  The Electrolyte Circulation System  The Control System  The Machine
  11. 11.  POWER SUPPLY o Electrical Energy Is Using To Work ECM, For This Power Lots Of Specialties Includes. o Electric Current Density Must Be High. o The Space Between Electrode And Work piece Must Be Very Short For Higher Accuracy.
  12. 12.  ELECTROLYTE CIRCULATION SYSTEM  The Entering Pressure Must Be Between 0.15 To 3 MPA . o The Electrolyte System Must Include a Strong Pump.  The Electrolyte Is Stored In a Tank . o System Also Includes A Filter , Sludge Removal System , And Treatment Units.
  13. 13.  CONTROL SYSTEM  Control Parameters Includes : -> Voltage. -> Inlet and Outlet Pressure Of Electrolyte. -> Temperature Of Electrolyte.  The Current Is Dependent On The Parameters Given Above And The Feed Rate.
  14. 14.  THE MACHINE  The Machine Is a Major Subsystem Of The ECM .  It Includes The Table , Frame , Work Enclosure ( prevents the electrolyte from Spilling ) , The Work Head ( Where the tool Is Mounted ) .  The Tools ( electrodes ) are Also Part Of The Machine System.
  15. 15.  ADVANTAGES OF ECM  No mechanical force.  There is no cutting forces therefore clamping is not required except for controlled motion of the work piece.  There is no heat affected zone.  Very accurate.  Relatively fast.  Can machine harder metals than the tool.  No material corrosion.  Provides smooth surfaces.  More sensitive and repeatable.
  16. 16.  DISADVANTAGES OF ECM  Solution usage In : • Pump , tank , pipe , filter .  More expensive than conventional machining.  Need more area for installation.  Electrolytes may destroy the equipment.  Not environmentally friendly (sludge and other waste)  The effect of the toxic gases and aerosols produced in the course of ECM.  The risk of an electric shock.  The danger of a burn in the case of a short circuit between the positive and negative leads.  Mechanical factors.  Material has to be electrically conductive.
  17. 17.  APPLICATION OF ECM  The most common application of ECM is high accuracy duplication. Because there is no tool wear, it can be used repeatedly with a high degree of accuracy.  It is also used to make cavities and holes in various products.  It is commonly used on thin walled, easily deformable and brittle material because they would probably develop cracks with conventional machining.
  18. 18.  APPLICATIONS IN INDUSTRIES  Applications are valid for highly sensitive working areas like; electronic, air and space industries.  It has also contains many benefits that in industries like Telecommunication , Automotive and Defense industries.
  19. 19.  ECONOMICS  The process is economical when a large number of complex identical products need to be made (at least 50 units) .  Several tools could be connected to a cassette to make many cavities simultaneously. (i.e. cylinder cavities in engines) .  Large cavities are more economical on ECM and can be processed in 1/10 the time of EDM.
  20. 20.  PRODUCTS  The two most common products of ECM are turbine/compressor blades and rifle barrels. Each of those parts require machining of extremely hard metals with certain mechanical specifications.  Some of these mechanical characteristics achieved by ECM are: Stress free grooves. *Any conductive metal can be machined. *Repeatable accuracy of 0.0005”. *High surface finish. *Fast cycle time.
