- 1. N.E.C.S. GROUP OF INISTUTIONS SEMINAR ON ELECTR CHEMICAL MACHINING PRESTENTED BY: ABHISHEK Kr. 7911222
- 2. INTRODUCTION Well I am Abhishek Kumar.And I'm from Karnal.Regarding my educatation qualification,I am doing b.tech. from necs group of institution. Which is affiliated by kurukshetra university.And today my seminar topics is electro chemical machining process.
- 4. Definition of ECM Process Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods.
- 5. Working Of ECM Process In the ECM process, a cathode (tool) is advanced into an anode (workpiece). The pressurized electrolyte is injected at a set temperature to the area being cut. The feed rate is the same as the rate of "liquefication" of the material. The gap between the tool and the workpiece varies within 80–800 micrometers (0.003–0.030 in.)
- 6. As electrons cross the gap, material from the work piece is dissolved, as the tool forms the desired shape in the work piece. The electrolytic fluid carries away the metal hydroxide formed in the process.
- 8. Advantage Of ECM Process There are following advantage of ecm process which is discussed below. ★ Tool does not contact the workpiece so tool life is increase. ★There is less tool wear in ecm.
- 9. ★less heat no stress are produce. ★This method works even on very hard and brittle work piece .
- 10. Disadvantage Of ECM Process ★the acidic electrolyte poses the risk of corrosion to tool,workpiece and equipment. ★Only electrically conductive materials can be machined.
- 11. Application Of ECM process ★Die sinking operation. ★Drilling jet engine turbines blades. ★Multiple hole drilling. ★jet engines.
