摘要
微电火花加工是一种非常规的金属去除技术,可有效加工难以切割的导电材料。它通过提供适当的表面形貌以促进细胞粘附,在改造金属骨植入物表面以提高生物相容性方面具有巨大潜力。然而,研究加工性能仍然非常重要。本文研究了对 Ti-6Al-4V 合金进行微线切割加工的材料去除率(MRR)和表面粗糙度(SR)。采用田口三水平设计来观察电容和间隙电压的影响。此外,方差分析(ANOVA)和灰色关系分析(GRA)可用于研究各参数的贡献,并为多输出优化找到最佳组合。结果表明,在 10 nF 和 90 V 条件下,MRR 最高,可达 1.72*10-2 mm3/s;在 1 nF 和 90 V 条件下,SR 最小,可达 0.309 µm。最后,计算了 10 nF 和 90 V 电压下多重输出性能的最佳参数。
Optimization of µ-WEDM Parameters for MRR and SR on Ti-6Al-4V
Micro EDM is unconventional metal removing technique that is effective in machining hard-to-cut conductive materials. It has a big potential in modifying surfaces of metallic bone implants for better biocompatibility by providing proper surface topography to ease cell adhesion. However, it is still important to study machining performance. This paper investigates material removal rate (MRR) and surface roughness (SR) of micro WEDM on Ti-6Al-4V alloy. Three level Taguchi’s design was implemented to observe the effect of capacitance and gap voltage. Moreover, analysis of variance (ANOVA) and grey relation analysis (GRA) allowed to investigate contribution of each parameter and find their best combination for multiple output optimization. Results showed that highest MRR of 1.72*10-2 mm3/s can be achieved at 10 nF and 90 V values, while smallest SR of 0.309 µm can be achieved at 1nF and 90 V. In addition, the contribution and significance of capacitance on MRR and SR was considerably higher than the effect of gap voltage. Lastly, the optimal parameters for multiple output performance were calculated at 10 nF and 90 V values.
