Q. |
Which of the following material properties sets restrictions to use wire cut EDM? |
A. | material type |
B. | melting point |
C. | material hardness |
D. | electrical conductivity |
Answer» D. electrical conductivity | |
Explanation: as the electrode wire does not get heated during machining, the problems with electrode wear are not an issue like in the case of die-sink ed machining and it is possible to use wire cut edm also for materials with high melting ranges. the material hardness sets no restrictions. the only restriction is that the material needs to be electrically conductive. |
