摘  要:通过同轴静电雾化切削雾化、荷电性能及铣削铝合金试验,研究了电压和内外流体类型对雾化形态、雾化电流与稳定性、切削力的影响。结果表明,在适用于切削的稳定锥射流模式下增大喷嘴电压,雾化电流增加、稳定性降低。内外流体中纳米颗粒的加入都会增大雾化电流,降低雾化稳定性。外流体中加入纳米颗粒切削力显著降低,内流体中加入纳米颗粒切削力有所增大。内流体为去离子水,外流体为蓖麻油基纳米流体时获得最低的切削力,为同轴静电雾化切削的优化内外流体组合。The influence of voltage and fluid type on atomization,atomization current and stability,cutting force were studied by coaxial electrostatic atomization cutting atomization,charge performance test and milling aluminum alloy test.The results show that when the nozzle voltage is increased,the atomization current is increased and the stability is decreased.The addition of nanoparticles in internal and external fluid can increase atomization current and decrease atomization stability.The cutting force of nanoparticles in the outer fluid decreases significantly,the cutting force increases when the inner fluid is added with nanoparticles.When the inner fluid is deionized water and the outer fluid is castor oil-based nanofluids,the lowest cutting force can be obtained,which is the optimal combination of internal and external fluid for coaxial electrostatic atomization cutting.
