正交磁场对电火花单脉冲放电间隙的影响
Investigation of Discharge Gap in Orthogonal Magnetic Field Assisted Dry Single-spark EDM
摘要
Abstract
The experiments for comparing the discharge gaps in EDM and MF-EDM were conduc-ted.Then the effects of magnetic field strength,open circuit voltage,capacitance and extension length of toolelectrode on discharge gaps were analyzed.The experimental results show that the discharge gaps increase with the increases of the magnetic field strengths.The open-circuit voltages and dis-charge capacitances do not have significant effects on the discharge gaps.In addition,the increases of the electrode extension lengths lead to the decreases of discharge gaps.Finally,the fractional factorial analysis of the experimental data shows that the magnetic field strengths,the extension lengths of toolelectrodes and their interaction are the main factors that affect the discharge gaps in MF-EDM.关键词
