線切割放電加工機放電點偵測系統與方法

在線切割放電加工製程中,放電點分布之均勻與否,與加工品質以及斷線機率息息相關,放電點分布不均,不僅容易造成斷線,亦難獲得較佳之加工面粗糙度。然而,個別放電點的位置不僅難以預測,而且在加工過程之中,亦難利用光學儀器或其他方法予以觀察。本發明利用比較上、下導電塊電流差異之方法,以微處理器控制電路即時推算放電點的位置,同時加以紀錄,並能將放電點位置的資料透過輸出入埠,傳給外部裝置,放電加工機之控制電路可以據以調整加工參數,使放電點分布趨於平均。 In the Wire Electrical Discharge Machining (WEDM) process, the distribution of the electrical discharge is one of the major factors deciding the surface finishing quality of the workpieces. However, the locations of electrical discharges are difficult to be observed by any optical method during the machining process. The invention proposed a method, in which a microcontroller-based system makes use of the difference of the electrical currents pasting through the upper and lower conducting seats, to estimate the location of every single electrical discharge on a real-time basis. The discharge location data are recorded and can be transferred to any outer device through the input/out port embedded in the system. The data could be helpful to the control circuit of the WEDM machine tools in determining the most appropriate combination of machining parameters.
