针对电化学放电加工中随加工深度增加，加工速度和加工质量降低的问题，提出了基于力反馈控制进给方式的加工方法，分析了基于力反馈进给电化学放电加工的工作机理。通过与常规的恒速进给、重力进给等加工方式的对比实验研究，发现力反馈进给的电化学放电加工能很好地改善孔的入口质量、提高加工速度，并获得较大的极限加工深度，同时，孔的锥度也明显减小。实验结果表明，基于力反馈控制进给的电化学放电加工方法在非导电脆硬材料的微细加工中有很大的潜力。

To solve the problems such as machining speed reduction and workpiece accuracy decrease in electrochemical discharge machining (ECDM) with increased machining depth ,a new ECDM method based on force feedback feeding was proposed. The machining principle of the new method was analyzed. Experiments were conducted to compare the machining performance used proposed method with common ECDM methods with a constant speed feeding system or a gravity feeding system. It can be found that the workpiece accuracy ,machining speed and maximum machining depth are greatly improved by using the force feedback feeding based on ECDM method. The results show that the method has great potential in the micro machining of hard and brittle insulating materials.
