摘要

对于任何过程，建模都是研究各种参数对其性能指标影响的最佳方式。长期以来，与其他技术相比，数值建模一直是研究人员感兴趣的主题，因此，使用该技术在电火花加工领域进行了更多的工作。在数值分析中，能量传递的一部分是一个关键参数，它取决于工件-工具的组合。研究人员已经假设了这个参数的恒定值或给定范围，但在任何文献中都没有确切的值。本文提出了一种新的方法，通过结合实验结果和有限元分析（FEA）来估计电火花加工过程中传递到工件的能量份额。为了验证该模型，进行了验证实验，仿真结果与实验结果吻合良好。【2018年11月17日提交；2019年1月27日接受】

A Simulation-based Approach for Modeling of Fraction of Energy Transfer to Workpiece in Electrical Discharge Machining

For any process, modelling is the best way to investigate the effect of various parameters on its performance measures. The numerical modelling has been the subject of interest for researchers for a long time as compared to other techniques and hence more work has been recorded in the field of EDM using this technique. In numerical analysis, a fraction of energy transfer is a critical parameter and it depends on the workpiece-tool combination. Researchers have assumed constant value or given range for this parameter but no exact value has been reported in any literature. This paper presents a novel approach to estimate the fraction of energy transfer to the workpiece during the EDM process using a combination of experimental results and finite element analysis (FEA). To validate the model, confirmation experiments were carried out which showed good agreement between simulation and experimental results. [Submitted 17 November 2018; Accepted 27 January 2019]

期刊介绍： Manufacturing contributes significantly to modern civilization and creates momentum that drives today"s economy. Much research work has been devoted to improving manufactured product quality and manufacturing process efficiency for many decades. Thanks to recent advances in computer and network technologies, sensors, control systems and manufacturing machines, manufacturing research has progressed to a new level. In addition, new research areas in manufacturing are emerging to address problems encountered in the evolving manufacturing environment, such as the increasing business practice of globalisation and outsourcing. This dedicated research journal has been established to report state-of-the-art and new developments in modern manufacturing research.
