过程稳定性对纳秒脉冲电解加工精度的影响
Effects of Process Stability on Precision of Micro-ECM Using Nanosecond Pulse Current
摘要
Abstract
While the nanosecond pulses current is applied into the electrochemical micro-machining, the stability of the machining process is an important factor affecting the machining precision due to the very small inter-electrode gap. The experimental system is developed according to the relationship of the precision and the stability. The electrode nozzle is devised to conduct the electrolyte flowing along the axis direction. The current sensor is used to detect real-time machining process state. The method for locating short-circuit is proposed to determine the initial inter-electrode gap exactly. The experiments are carried out to investigate the effect of the process parameters on the stability and the precision. The result shows that calm flowing and renewing electrolyte achieves more stable process than resting electrolyte.While the pulse on-time is less than 25 ns, the stability decreases obviously. The stable process and the good precision are well implemented with pulse on-time 40 ns,voltage 4 Ⅴ and duty factor 1 : 10.关键词
