| 摘 要： | 针对电火花加工中电极损耗问题, 提出轴向补偿电极损耗的钻孔方法, 利用黄铜和紫铜2种不同电极材料在超精密电火花加工机床(Sarix SX-200hpm)上, 对钛合金进行不同深度盲孔加工实验, 对比了该法与电极损耗无补偿加工的差异。结果表明，利用该方法加工的盲孔深度能接近预期深度，且紫铜电极加工的盲孔形貌更好。

| Abstract: | Aiming at the problem of electrode wear in electrical discharge machining(EDM), a drilling method for axial compensation of electrode wear is proposed. A series of blind holes of different intended depths are drilled on the micro-EDM machine (Sarix SX-200hpm) using the proposed method and they are compared with holes drilling without compensation. The brass and copper are employed as tool electrode and the workpiece is Titanium alloy (TC4). As a result the depth of blind hole processed by this method can be close to the expected and the morphology of blind hole processed with the copper electrode is better. |
