摘要
针对电化学放电线切割加工方法,基于润湿的供液方式,搭建了基于力信号反馈控制进给的加工实验平台,设计了基于力信号反馈控制进给速度的模糊控制系统,并将模糊控制系统应用到力信号反馈控制进给的加工实验平台上,进行了微槽加工实验,发现与PID控制算法相比较,模糊控制系统有效改善了微槽两侧的过切现象,显著提高了加工效率,验证了模糊控制系统在电化学放电线切割加工过程中的实用性。
Aiming at the Wire Electrochemical Discharge Machinging(WECDM)method,a processing experiment platform was built based on force feedback control feeding with liquid supply method of wetting,and a fuzzy control system based on force feedback control feeding speed was designed.The fuzzy control system was applied to the processing experiment platform of force feedback control feeding,and the micro-groove processing experiment was carried out.Compared with the PID control algorithm,the fuzzy control system effectively improved the over-cutting phenomenon on both sides of the micro-groove,and significantly improved the processing efficiency,which verified the practicability of the fuzzy control system in the process of WECDM.
