摘要
为提高微细电火花铣削加工效率和加工精度,研究了基于电极等损耗分层去除微细电火花铣削加工工艺的关键技术:微小电极的运动轨迹规划、电极的损耗及补偿策略。同时分析了微细电火花铣削加工过程中直径为0.7 mm的Cu-Si材料电极在采用合理的轨迹规划下,分层厚度和轨迹重叠率对加工精度和加工效率的影响。结果表明,合理的轨迹规划和精确的电极损耗补偿算法在不同加工阶段选择合理的分层厚度和轨迹重叠率能大大提高微细电火花铣削加工效率和加工精度。
To improve the machining efficiency and precision, the micro electrical discharge milling technology based on uniform wear method is studied, including paths design of micro electrode and electrode wear compensation. The impact on machining precision of paths design and tool wear with the optimal paths using Cu-Si electrode of φ0. 7 mm is analyzed during the machining process. It is indicated that the machining efficiency and precision can be improved greatly during the micro-EDM when the optimal paths and slicing thickness, precise electrode wear compensation algorithm and reasonable overload ratio are adopted.
