摘要： In hydrodynamic thrust bearing, common micro-grooves with helical or herringbone forms are generally to ensure the bearing load capacity and reduce leakage of lubricant, consistent with the design or size requirements of grooves. In this investigation, the electrical field distribution and anodic dissolution of helical grooves in electrochemical micro-machining process can be predicted by using COMSOL Multiphysics TM software. The processing equivalent is based on the chemical composition of the workpiece. The micro-helical grooves are hollowed out of hydrodynamic thrust bearing using a DC and pulse power supply, and experiment results are compared with simulation results. The experimental results demonstrate that the fine surface of helical grooves can be obtained with a depth of 4.9 μm in machining time of 3 s by using a pulse power supply of 5 kHz. To eliminate the effect of such factors as flush flow, temperature difference between workpiece and tool, and formation of hydrogen bubble barriers, the k values of these factors are considered for amendment to get more accurate simulation results. 其他題名： Int J Adv Manuf Technol 出版者： London: Springer-Verlag 出版日期： 2013-02-01 出處： International journal of advanced manufacturing technology, 2013-02, Vol.64 (5-8), p.813-820 資源來源： EBSCOhost Academic Search Premier 版權： Springer-Verlag London Limited 2012 版權： The International Journal of Advanced Manufacturing Technology is a copyright of Springer, (2012).
