doi:10.3969/j.issn.1004-132X.2022.15.005

Abstract

Abstract: ECCG process was an effective method to solve wheel loading issue in grinding of ductile metal parts. Keeping the balance between loading material formation on wheel surfaces and the electrolysis was the key to successful application of this process. According to electrochemical theory and grinding mechanism， a new method was proposed to quantitatively evaluate wheel loading degree with electrolysis current， and the working voltages for different grinding parameters were determined during ECCG processes. Both of aluminum AA6061 and titanium TC4 were ground by this machining process at the pseudo-steady states. The results show that the ECCG process holds strong expandability and may be used for manufacturing large ductile metal parts.

摘要： 电化学清理磨削工艺（ECCG）可有效解决延塑性金属磨削时的砂轮黏附问题，该工艺成功应用的关键是使砂轮表面黏附物的形成率与其电解率相平衡。基于电化学原理和磨削机理分析，提出一种利用电解电流定量评估砂轮黏附率的新方法，确定了不同磨削参数下ECCG工艺所需的工作电压。在拟稳态条件下，利用该工艺对AA6061铝合金和TC4钛合金工件进行磨削加工。研究结果表明，ECCG工艺具有较强的可扩展性，可用于加工大型延塑性金属零件。
