| 摘 要： | 针对微细电火花线切割加工表面的微观特殊形貌，研究了该加工表面的支承特性和润滑性能，对微细电火花线切割加工的工程应用具有重要的参考价值.应用截面的二值图求得截面积，绘制微细电火花线切割加工表面的表面支承面积率曲线，应用MATLAB的PDETOOL工具箱得出微细电火花线切割加工单个微坑内的油膜压力场.结果表明，微细电火花线切割加工表面的峰谷分布比较规则，在支承面积率tp=49.228%时，水平截距c=8%，当tp=80%时，c=232%；微细电火花线切割加工表面的峰区材料体积增加迅速，表面具有较好的支承特性；表面越粗糙，表面的支承性能越差，而核心区液体滞留性越好；微坑储存润滑油，显著改善了加工表面的润滑状况；接触表面在油膜压力作用下接触均匀，对冲击压力有缓冲作用，提高了微细电火花线切割加工表面的耐磨性能.

| Abstract: | In order to provide important reference for the practical application of micro-wire electrical discharge machining(micro-WEDM),the bearing and lubrication characteristics of the micro-WEDM surface were investigated by analysis of its special micro-morphology.The surface bearing area ratio curve for the micro-WEDM surface was drawn on the basis of the section area obtained with the binary image of cross-section,and the oil film pressure field for single micro-pit on the micro-WEDM surface was gained by using... |
