Description
本發明係有關於一種對刀裝置與對刀方法，特別是有關於一種電化學加工之對刀裝置與對刀方法。The present invention relates to a tool setting device and a tool setting method, and more particularly to a tool setting device and a tool setting method for electrochemical machining.
近年來各類型產品之發展趨勢除了提昇功能之外，也要求輕薄短小，尤其是在3C電子產品、生醫及新興能源等領域。因此，產品之各項元件的加工尺寸與加工品質的要求也相形提高，此外應用於產品之材料特性諸如硬度與延展性等亦漸趨多樣化。基於上述原因，若單純以傳統機械加工技術進行加工是難以達到現今使用者對於品質之要求，且有些材料是無法用傳統機械加工技術進行加工。In recent years, in addition to improving functions, the development trend of various types of products has also required light and thin, especially in the fields of 3C electronic products, biomedical and emerging energy. Therefore, the processing dimensions and processing quality requirements of the various components of the product are also increased, and the material properties such as hardness and ductility applied to the product are gradually diversified. For the above reasons, it is difficult to achieve the quality requirements of today's users if they are simply processed by conventional machining techniques, and some materials cannot be processed by conventional machining techniques.
目前電化學加工突破傳統機械加工於精度上之限制，因而電化學加工成為兼具量產性與高精度之加工技術。近年來電化學加工受到廣泛研究與應用，其因為不具有切削力作用，因此無殘留切削應力的缺點，且具有不受限於加工件之材料硬度、強度及韌性影響等加工優勢。At present, electrochemical machining breaks the limitation of precision in traditional machining, so electrochemical machining has become a processing technology with both mass production and high precision. In recent years, electrochemical machining has been widely studied and applied. Since it does not have a cutting force, it has no disadvantage of residual cutting stress, and has processing advantages such as being unaffected by the hardness, strength and toughness of the material of the workpiece.
運用電化學加工對加工件進行加工前，加工電極必須進行對刀程序，即加工電極相對於加工件進行定位，以得知加工電極與加工件間之座標相對關係。於現今技術，加工電極進行對刀程序時，加工電極被帶動而往加工件移動，加工電極慢慢靠近加工件直到接觸加工件之表面為止，如此電化學加工系統即可得知加工電極與加工件間之座標相對關係，也就完成加工電極之對刀程序。Before machining the workpiece with electrochemical machining, the machining electrode must perform the tool setting procedure, that is, the machining electrode is positioned relative to the workpiece to know the relative relationship between the machining electrode and the workpiece. In the current technology, when the machining electrode performs the tool setting process, the machining electrode is driven to move to the workpiece, and the machining electrode is slowly approached to the workpiece until it contacts the surface of the workpiece, so that the electrochemical processing system can know the machining electrode and the machining. The relative relationship between the coordinates of the pieces also completes the tool setting procedure for the machining electrodes.
由上述可知，加工電極進行對刀程序時，加工電極會接觸加工件，如此加工電極容易受到損壞，而影響電化學加工之精度與加工電極之使用壽命。尤其加工電極之表面具有絕緣層下，絕緣層碰觸加工件後，可能會導致絕緣層剝落，如此即會影響加工精度。
It can be seen from the above that when the machining electrode performs the tool setting process, the machining electrode will contact the workpiece, so that the processed electrode is easily damaged, which affects the precision of the electrochemical machining and the service life of the machining electrode. In particular, the surface of the processing electrode has an insulating layer. When the insulating layer touches the workpiece, the insulating layer may peel off, which may affect the processing accuracy.
本發明之目的之一，在於提供一種電化學加工之對刀裝置與對刀方法，其在進行對刀程序時，依據加工電極與加工件間之能量狀態控制加工電極之移動，以完成對刀程序。One of the objects of the present invention is to provide a tool setting device and a tool setting method for electrochemical machining, which control the movement of the machining electrode according to the energy state between the machining electrode and the workpiece during the tool setting process to complete the tool setting. program.

實施例之對刀裝置可包含一對刀模組60，其耦接電源模組10與控制模組33。加工電極20進行對刀程序時，對刀模組60可控制電源模組10提供適當電量之電源至加工電極20與加工件50，如此可避免提供過大電量之電源至加工電極20與加工件50，而可降低加工電極20在對刀過程中對加工件50進行加工的機會，而降低讓加工件50發生電解現象的機會。對刀模組60可為電腦或為數位邏輯晶片。The tool setting device of the embodiment may include a pair of knife modules 60 coupled to the power module 10 and the control module 33. When the processing electrode 20 performs the tool setting process, the tool setting module 60 can control the power module 10 to supply a power source of a proper amount of electricity to the processing electrode 20 and the processing member 50, so as to avoid providing a power source of excessive power to the processing electrode 20 and the workpiece 50. Moreover, the opportunity for the processing electrode 20 to process the workpiece 50 during the tool setting process can be reduced, and the chance of electrolysis of the workpiece 50 is reduced.

With the workpiece 50. In this way, the tool setting module 60 controls the power module 10 to supply a proper amount of power according to the power information, and can reduce the chance of the workpiece 50 being electrolyzed during the tool setting process. In the embodiment, the power of the power source for performing the tool setting process is smaller than the power amount of the power source for electrochemical processing.

The reference information may include a plurality of comparison information and a corresponding plurality of reference power sources, and the comparison information may include a plurality of workpiece state comparison information and a plurality of processing electrode states. The reference power supply may include a plurality of reference voltages for comparison information and a plurality of electrolyte state comparison information. The comparison information is related to the tool setting process, such as the material of the workpiece, the processing area of the processing electrode, the type of the electrolyte, and the concentration of the electrolyte. The comparison information is not limited to the above-mentioned workpiece state, the processing electrode state and the electrolyte state, and the comparison information is not limited to the state of the above three, and the comparison information can be adjusted as needed. The reference voltage of the power supply table is used for obtaining power information for the tool setting module 60, and the reference voltage is determined in advance according to various tool setting conditions and states through electrochemical machining test, and is used as a power source for determining the tool setting process. Reference.
實施例中，透過輸入介面61所輸入之對刀資訊對應於電源對照表之該些對照資訊，對刀資訊包含目前進行對刀程序之加工件50之狀態、加工電極20之狀態與電解液45之狀態。處理單元62會依據對刀資訊查詢並比對預先建立於資料庫63的對照資訊，比對到相同於對刀資訊的對照資訊，可獲得對應之參考電壓，此參考電壓即為電源資訊，如此可決定進行對刀程序之電源的電量。處理單元62依據獲得之電源資訊產生電源切換訊號，而提供至電源模組10，以控制電源模組10提供對應之電源。In the embodiment, the tool setting information input through the input interface 61 corresponds to the comparison information of the power comparison table, and the tool setting information includes the state of the workpiece 50 currently performing the tool setting process, the state of the processing electrode 20, and the electrolyte 45. State. The processing unit 62 compares and compares the comparison information pre-established in the database 63 according to the tool information, and compares the comparison information with the same tool information to obtain a corresponding reference voltage, which is the power information. The power of the power supply to the tool setting program can be determined. The processing unit 62 generates a power switching signal according to the obtained power information, and provides the power switching signal to the power module 10 to control the power module 10 to provide a corresponding power source.
舉例說明，例如對刀資訊為加工件50之材質為材質1，加工電極20之加工面積為加工面積A，而電解液45之種類為電解液Ⅱ，且其濃度為10％，處理單元62則可比對資料庫63中的對照資訊而得到對應之參考電壓為0.3V，處理單元62會以此0.3V作為電源資訊而對應產生電源切換訊號，以控制電源模組10提供0.3V之電源。For example, for example, the tool information is that the material of the workpiece 50 is material 1, the processing area of the processing electrode 20 is the processing area A, and the type of the electrolyte 45 is the electrolyte II, and the concentration thereof is 10%, and the processing unit 62 is Comparing the reference information in the database 63 to obtain a corresponding reference voltage of 0.3V, the processing unit 62 correspondingly generates a power switching signal with the 0.3V as the power information to control the power module 10 to provide a power of 0.3V.
此外，處理單元62若比對不到相同於對刀資訊的對照資訊時，其會尋找到兩相近於對刀資訊的對照資訊，而依照對應之兩參考電壓進行運算而求得電源資訊，例如使用內插法運算、平均運算或者其他運算方式。舉例來說，若加工件50之材質為材質1，加工電極20之加工面積為加工面積A，而電解液45之種類為電解液Ⅱ，且其濃度為7％，處理單元62比對資料庫63中的對照資訊而得到兩參考電壓為0.4V與0.3V，處理單元62即以0.4與0.3進行運算，而產生電源資訊，而決定對刀程序之電源的電量。由上述可知，對刀模組60會依據不同對刀資訊調整進行對刀程序之電源的電量。In addition, if the processing unit 62 compares the comparison information that is the same as the tool setting information, it will find the comparison information of the two similar tool information, and calculate the power information according to the corresponding two reference voltages, for example, Use interpolation, averaging, or other methods of operation. For example, if the material of the workpiece 50 is material 1, the processing area of the processing electrode 20 is the processing area A, and the type of the electrolyte 45 is the electrolyte II, and the concentration thereof is 7%, the processing unit 62 compares the database. According to the comparison information in 63, the two reference voltages are 0.4V and 0.3V, and the processing unit 62 operates at 0.4 and 0.3 to generate power information, and determines the power of the power supply to the tool. As can be seen from the above, the tool setting module 60 adjusts the power of the power supply of the tool setting program according to different tool setting information.
對刀模組60控制電源模組10供應電源後，由於加工電極20與加工件50皆位於電解液45中，所以加工電極20與加工件50間會建立電場，而具有能量。此時，對刀模組60控制該控制模組33而驅動移動軸31移動，進而帶動加工電極20朝加工件50移動，以進行對刀程序。對刀裝置更包含一擷取模組70，其耦接加工電極20與加工件50，而用於擷取進行對刀程序之加工電極20與加工件50間的能量，並產生對應之偵測訊號，例如擷取加工電極20與加工件50間的電流或者電壓。此外，擷取模組70亦可為其他偵測能量的電路。After the tool module 60 controls the power module 10 to supply power, since the machining electrode 20 and the workpiece 50 are both located in the electrolyte 45, an electric field is established between the machining electrode 20 and the workpiece 50, and energy is generated. At this time, the tool setting module 60 controls the control module 33 to drive the movement shaft 31 to move, thereby driving the machining electrode 20 to move toward the workpiece 50 to perform a tool setting procedure. The tool setting device further includes a capturing module 70 coupled to the processing electrode 20 and the processing member 50 for capturing energy between the processing electrode 20 and the processing member 50 for performing the tool setting process, and generating corresponding detection. The signal, for example, draws current or voltage between the processing electrode 20 and the workpiece 50. In addition, the capture module 70 can also be other circuits that detect energy.
對刀模組60耦接擷取模組70，以接收表示能量之偵測訊號。於實施例中，對刀模組60為數位架構，所以其更包含一訊號轉換電路65，其耦接擷取模組70，並轉換類比式之偵測訊號為數位式之偵測訊號。實施例中，訊號轉換電路為一類比數位轉換電路。對刀模組60亦可採用類比電路，而直接接收類比式之偵測訊號，所以本發明之對刀模組60可不需要訊號轉換電路65。The tool setting module 60 is coupled to the capture module 70 for receiving a detection signal indicating energy. In the embodiment, the tool setting module 60 is a digital structure, so it further includes a signal conversion circuit 65 coupled to the capture module 70 and converting the analog detection signal to a digital detection signal. In an embodiment, the signal conversion circuit is an analog to digital conversion circuit. The tool setting module 60 can also use an analog circuit to directly receive the analog type detection signal. Therefore, the tool setting module 60 of the present invention does not require the signal conversion circuit 65.
進行電化學加工之對刀程序過程，若加工電極20朝加工件50移動而欲接觸到加工件50之前（如第二圖所示），加工電極20與加工件50之間將會發生短路狀態，當短路狀態發生之前或發生時，能量會有明顯變化，所以藉由對刀模組60之處理單元62即時監測能量之變化，可即時判斷進行對刀程序之過程中是否要發生短路狀態，而可判斷出加工電極20是否已欲接觸到加工件50，判斷加工電極20欲接觸到加工件50時，處理單元62控制該控制模組33停止移動加工電極20，控制模組33會記錄加工電極20目前之座標，而完成對刀程序。由於加工電極20並未接觸加工件50，所以可對對刀之座標進行補償，補償值可預先依據各種對刀條件與狀態經過電化學加工試驗而決定，例如經過試驗而得知發生能量明顯變化時，加工電極20與加工件50間之間距。加工電極20進行對刀程序而接觸加工件50之前，對刀模組60會停止加工電極20移動，所以加工電極20進行對刀程序之過程，加工電極20與加工件50之間皆具有一間距，以避免兩者接觸。During the tool setting process of the electrochemical machining, if the machining electrode 20 is moved toward the workpiece 50 and is to be in contact with the workpiece 50 (as shown in the second figure), a short circuit condition will occur between the machining electrode 20 and the workpiece 50. When the short-circuit state occurs or occurs, the energy changes significantly. Therefore, by directly monitoring the change of the energy of the processing unit 62 of the tool setting module 60, it is possible to immediately determine whether a short-circuit state occurs during the process of setting the tool. The processing unit 62 controls the control module 33 to stop moving the processing electrode 20, and the control module 33 records the processing. The electrode 20 is currently at the coordinates and the tool setting procedure is completed. Since the processing electrode 20 does not contact the workpiece 50, the coordinates of the tool can be compensated, and the compensation value can be determined in advance according to various tool setting conditions and states through electrochemical processing tests, for example, it is known through experiments that significant changes in energy occur. At the same time, the distance between the processing electrode 20 and the workpiece 50 is obtained. Before the machining electrode 20 performs the tool setting process and contacts the workpiece 50, the tool setting module 60 stops the movement of the machining electrode 20. Therefore, the machining electrode 20 performs the process of the tool setting process, and the machining electrode 20 and the workpiece 50 have a spacing therebetween. To avoid contact between the two.
此外，對刀模組60更可包含一濾波電路66，其耦接訊號轉換電路65與處理單元62，濾波電路66用於濾波數位偵測訊號，以濾除數位偵測訊號中的雜訊，並將濾波後之數位偵測訊號傳輸至處理單元62。處理單元62依據濾波後之數位偵測訊號可得知進行對刀程序之加工電極20與加工件50間之能量的狀態。處理單元62判斷加工電極20欲接觸到加工件50之前，可產生一控制訊號，處理單元62傳輸控制訊號至一第二輸出電路67，第二輸出電路67耦接控制模組33，以傳輸控制訊號至控制模組33。控制模組33依據控制訊號控制移動軸31停止移動。如此，加工電極20於進行對刀程序可避免接觸加工件50，而可避免加工電極20與加工件50受到損壞。此外，實施例可提高加工電極20之移動速度，如此可降低對刀時間，而降低進行電化學加工前之前置時間。In addition, the tool module 60 further includes a filter circuit 66 coupled to the signal conversion circuit 65 and the processing unit 62. The filter circuit 66 is configured to filter the digital detection signal to filter out noise in the digital detection signal. The filtered digital detection signal is transmitted to the processing unit 62. The processing unit 62 can know the state of the energy between the processing electrode 20 and the workpiece 50 of the tool setting program according to the filtered digital detection signal. The processing unit 62 determines that the processing electrode 20 is to be in contact with the processing member 50 to generate a control signal, the processing unit 62 transmits the control signal to a second output circuit 67, and the second output circuit 67 is coupled to the control module 33 for transmission control. Signal to control module 33. The control module 33 controls the movement axis 31 to stop moving according to the control signal. In this way, the machining electrode 20 can avoid the contact with the workpiece 50 during the tool setting process, and the machining electrode 20 and the workpiece 50 can be prevented from being damaged. In addition, the embodiment can increase the moving speed of the processing electrode 20, which can reduce the tool setting time and reduce the lead time before electrochemical processing.
處理單元62依據內部預設之參考門檻判斷偵測訊號所表示之能量的變化程度。處理單元62可以依據能量之狀態變化判斷進行對刀程序之加工電極20是否已欲接觸加工件50。The processing unit 62 determines the degree of change of the energy represented by the detection signal according to the internal preset reference threshold. The processing unit 62 can determine whether the processing electrode 20 that performs the tool setting procedure has contacted the workpiece 50 according to the state change of the energy.
由於進行對刀程序中發生短路狀態前或者發生時，能量會有明顯變化，所以可藉由該些變化而設定參考門檻，以進行比較而判斷是否要發生短路狀態。例如，加工電極20與加工件50間之電流會明顯變大，而間隙電壓明顯下降。因此，可依據上述之能量變化而設定不同之參考門檻，其可包含一電流最大極限值、一電流上升斜率極限值、一電壓最小極限值及一電壓下降斜率極限值。處理單元62可依據偵測訊號，而進行運算而得知電流之上升斜率以及電壓之下降斜率。參考門檻可經由輸入介面61而設定於處理單元62。上述判斷短路狀態之方式與參考門檻僅是實施例之一，並非限定處理單元62僅能運用上述之判斷方式與參考門檻。另外，上述之判定規則可選用其一，或者合併搭配組合。Since the energy changes significantly before or during the occurrence of the short circuit state in the tool setting program, the reference threshold can be set by the changes to determine whether or not the short circuit state is to be generated. For example, the current between the processing electrode 20 and the workpiece 50 becomes significantly larger, and the gap voltage drops significantly. Therefore, different reference thresholds may be set according to the energy change described above, which may include a current maximum limit value, a current rise slope limit value, a voltage minimum limit value, and a voltage drop slope limit value. The processing unit 62 can perform an operation according to the detection signal to obtain a rising slope of the current and a falling slope of the voltage. The reference threshold can be set to the processing unit 62 via the input interface 61. The manner of determining the short-circuit state and the reference threshold are only one of the embodiments, and the processing unit 62 is not limited to the above-mentioned determination mode and reference threshold. In addition, the above-mentioned determination rule may be used in one of them, or combined and combined.
為了避免能量變化僅是因為某些因素而短暫大於參考門檻，而並非是實際要發生短路狀態，進而讓對刀模組60誤判。處理單元62可進一步設定一時間門檻，當處理單元62判斷能量的狀態變化超過上述參考門檻，且持續超過所設定之時間門檻，如此即判定進行對刀程序中要發生短路狀態。In order to avoid the energy change, it is only because of some factors and is temporarily larger than the reference threshold, instead of actually causing a short circuit state, thereby causing the tool setting module 60 to misjudge. The processing unit 62 can further set a time threshold. When the processing unit 62 determines that the state of the energy changes beyond the reference threshold and continues to exceed the set time threshold, it is determined that a short circuit condition occurs in the tool setting procedure.
綜上所述，本發明電化學加工之對刀裝置與對刀方法依據對刀資訊與參考資訊獲得電源資訊，而決定加工電極進行對刀程序之電源的電量。此外，加工電極進行對刀程序之過程，可擷取加工電極與加工件間的能量，而依據能量之狀態控制加工電極之移動，如此加工電極進行對刀程序中，加工電極與加工件之間皆具有間距，而可避免加工電極進行對刀程序中接觸加工件。In summary, the tool setting device and the tool setting method of the electrochemical processing of the present invention obtain the power information according to the tool information and the reference information, and determine the power of the power source for processing the electrode to perform the tool setting process.
