电火花加工工艺及应用机械加工时,按照工具(车刀、铣刀、钻头、砂轮等)和工具与工件的相对运动的特点可分为车、铣、钻、刨、拉、磨等各种工艺方法和相应的机床设备。在电火花加工时,工具电极分不出车刀、铣刀、钻头等的特点,而工具和工件的相对运动也较简单(一般不用展成法而用印模法),所以上述传统的工序名称和机床设备的分类方法在电火花加工中便不确切,有些工 EDM process and application of mechanical processing, according to the characteristics of the tool (turning tools, milling cutters, drill bits, grinding wheels, etc.) and the relative movement of the tool and the workpiece can be divided into vehicles, milling, drilling, planing, Process methods and the corresponding machine equipment. In the EDM, the tool electrode points out the characteristics of turning tools, milling cutters, drill bits, etc., and the relative movement of the tool and the workpiece is relatively simple (generally do not have to use the law and impression), so the traditional process name And the classification of machine tools in EDM is not precise, some workers
