| Abstract: | Aiming at Near Dry powder mixed EDM in gas, liquid, solid three-phase flow stable atomizing difficult shortcomings,proposed new double cracks near dry powder mixed EDM application MQL device and its atomization mechanism to promote stability were discussed. Experimental studies have shown that the use of double cracks near dry powder mixed EDM MQL can enhance the stability of the three-phase flow, improve atomization state , thereby changing the discharge gap and the discharge channel bit-shaped, improve surface quality. |
