由于电解加工精度不高、刀具设计困难、加工参数难以控制等原因，电解加工的实际应用受到了限制。在电解加工中对工具电极施加低频振动是提高加工精度和加工表面质量的有效技术之一。本文提出了一种分析方法，建立数学模型，在奋进评估这种新的和混合技术的金属去除机制。研究了电解加工中输入参数和加工条件对刀具振动有效性的影响。分析模型表明，有可能是一个很大的复杂性之间的关系的工具振幅和平衡间隙的大小，这可能会导致工具损坏，如果没有仔细考虑的问题。(C)2007年由Elsevier B.V.出版。
The practical application of electrochemical machining (ECM) is still limited because of its lack of accuracy, difficulty of proper tool design and insufficient control of the operating parameters. Application of low frequency vibration to the tool electrode in electrochemical machining is one of the effective techniques for improving accuracy and quality of the machined surface. This paper presents an analytical approach to establish mathematical model in an endeavor to asses the mechanism of metal removal for this novel and hybrid technique. The effect of input parameters and machining conditions on the effectiveness of tool vibration during ECM has been fully investigated. The analytical model reveals that there could be a great complexity in the relationship between the tool amplitude and the equilibrium gap size, which could lead to tool damage, if the problem has not been carefully considered.
