摘要
传统电火花铣削加工需在特定加工机床上实现,被加工工件尺寸与形状受机床限制,故将电火花铣削加工与六自由度串联机器人有机结合在一起,以此开展了一系列电火花铣削加工实验。首先,通过直线沟槽铣削加工探究电极尺寸、脉冲宽度和电极扫描速度对材料去除率和电极损耗率的影响;其次,通过曲线沟槽铣削加工探究本装置的加工精度,通过方形平面槽铣削加工研究铣削轨迹、轨迹重叠方式对加工的影响;最后,将基于六自由度串联机器人的电火花铣削加工装置应用于曲面工件的铣削加工。结果表明:基于六自由度串联机器人的电火花铣削加工具有很高的加工自由度且能实现较高的加工精度,具有很大的应用潜力。
Traditional EDM milling is achieved on a specific EDM machine tool,and the size and shape of the workpiece are limited by the EDM machine tool.EDM milling is organically combined with a 6-DOF serial robot,and the experiments of EDM milling based on the 6-DOF serial robot are carried out.Firstly,the effects of the electrode size,pulse width and electrode scanning speed on the material removal rate and electrode wear rate are explored through the EDM milling of the linear groove.Secondly,through the EDM milling of the curved groove,the machining accuracy of the experimental equipment is explored.Then,the effects of the milling path and path overlap mode on the machining results are studied through the EDM milling of the square plane groove.Finally,the EDM milling based on the 6-DOF serial robot is applied on the machining of the curved workpiece.The experimental results demonstrate that EDM milling based on a 6-DOF serial robot can have high machining degree of freedom and achieve high milling accuracy,which has great application potential.
