The invention relates to a precise electrolytic machining real-time feed control system. Controlled by a closed loop control system, the precise electrolytic machining real-time feed control system comprises a current sensor, a calculating circuit, a subtracter, a multiplying unit, a proportion regulator and an executor, wherein the current sensor is used for collecting current data in an electrolytic machining process; the calculating circuit is used for keeping a current waveform and sending out a cut-off signal of the control system when the current data is abnormal; the subtracter is usedfor obtaining a difference value between an actual current value and a template current value; the multiplying unit is used for obtaining an adjusting range of the difference value between the actualcurrent and a target control current; the proportion regulator is used for obtaining a feed speed regulating signal; and the executor is used for executing the feed speed regulating signal sent by theproportion regulator. The precise electrolytic machining real-time feed control system monitors the current change in the electrolytic machining process in real time and regulates the machining speedin real time according to a monitoring result so as to achieve a technical scheme of controlling feed of a machining electrode in real time, so that the machining gap is still in a set reasonable range, and the risk of short circuit due to the too small machining gap or influence on the machining precision due to the too large machining gap is prevented.
Description
technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a real-time feed control system and method for precision electrolytic machining. Background technique [0002] Electrolytic machining is a multi-disciplinary processing technology that integrates electrochemistry, fluid mechanics, electromagnetics, machinery and automatic control. It is a special process method that uses the principle of electrochemical anodic dissolution to realize the removal and processing of metal materials. It has the characteristics of high processing efficiency, no consumption of tool electrodes, no stress in processing, and good surface integrity. It is suitable for efficient and precise processing of various difficult-to-machine metal materials (stainless steel, titanium alloys, high-temperature heat-resistant alloys), especially for efficient removal Batch production and processing of parts of a large number of materials and processing of...
