Description

在啟動工具機之後進行模擬確認的加工方法與加工系統 After starting the machine tool, perform simulation confirmation processing Method and processing system

本揭露實施例是有關於一種加工方法及加工系統，且特別是有關於一種在啟動工具機之後進行模擬確認的加工方法與加工系統。 The embodiment of the disclosure relates to a processing method and processing system, and in particular to a processing method and processing system that performs simulation confirmation after starting the machine tool.

電腦數值控制(computer numerical control，CNC)工具機廣泛應用於工業界的加工操作。在進行操作時，須載入加工程式於CNC控制器中，並且必須設定關於機台的各種實際參數值，如刀長值、刀塔參數、各種補正值(offset)等。當前述加工程式以及各種實際參數值載入設定完成後，即可按下開始鍵(cycle start)對工件進行加工。然而，若是有人為操作失誤發生時，例如加工程式載入錯誤、各種實際參數值輸入錯誤等，即會發生異常(例如撞車)的情形。 Computer numerical control (CNC) machine tools are widely used in industrial processing operations. During operation, the machining program must be loaded into the CNC controller, and various actual parameter values of the machine must be set, such as tool length value, turret parameter, various offset values (offset), etc. After the aforementioned processing program and various actual parameter values are loaded and set, press the cycle start button to process the workpiece. However, if man-made operating errors occur, such as processing program loading errors, various actual parameter values input errors, etc., abnormalities (such as a car crash) will occur.

業界目前使用一些方法來減少或避免上述失誤發生。第一種是手寫數值控制(NC)程式，並使用模擬軟體進行刀具路徑模擬。此類的模擬軟體包括(1)CNC控制器內的模擬軟體、或(2)在一般電腦上獨立執行的模擬軟體。 The industry currently uses some methods to reduce or avoid the above-mentioned mistakes. The first is to write numerical control (NC) programs and use simulation software for tool path simulation. Such simulation software includes (1) the simulation software in the CNC controller, or (2) the simulation software that runs independently on a general computer.

第二種是使用泛用型電腦輔助設計(computer-aided design，CAD)或電腦輔助製造(computer-aided manufacturing，CAM)軟體來產生NC程式，然後使用模擬軟體進行刀具路徑模擬。這類的模擬軟體包含(1)CNC控制器內的模擬軟體、(2)在一般電腦上獨立執行之模擬軟體、或者(3)CAD/CAM軟體裡面的切削模擬功能。 The second is to use general-purpose computer-aided design (CAD) or computer-aided manufacturing (CAM) software to generate NC programs, and then use simulation software for tool path simulation. This type of simulation software includes (1) the simulation software in the CNC controller, (2) the simulation software that runs independently on a general computer, or (3) the cutting simulation function in the CAD/CAM software.

第三種是使用客製化CAD/CAM軟體產生NC程式，然後對程式進行切削模擬，就如上述第一種和第二種。 The third is to use customized CAD/CAM software to generate NC programs, and then perform cutting simulation on the programs, just like the first and second above.

上述三種方式皆屬於非線上(non on-line)的模擬，而與在工具機上面進行的實際加工製程沒有直接連結。因此，就算切削模擬無誤，實際在工具機上面啟動NC程式進行加工仍可能會出錯，例如，加工零點可能設定錯誤等、或者是操作人員裝錯刀具。 The above three methods are all non-on-line simulations, and are not directly connected to the actual machining process performed on the machine tool. Therefore, even if the cutting simulation is correct, there may still be errors when starting the NC program on the machine tool for processing. For example, the machining zero point may be set incorrectly, or the operator may install the wrong tool.

因此，需要一種能解決上述問題之加工方法及加工系統。 Therefore, there is a need for a processing method and processing system that can solve the above-mentioned problems.

本揭露之目的在於提出一種在啟動工具機之後進行模擬確認的加工方法與加工系統，能在工具機進行加工程序期間(即線上)，根據實際的加工相關參數進行模擬，以避免浪費加工時間及成本並能提升產品良率。 The purpose of this disclosure is to propose a processing method and processing system for simulation confirmation after starting the machine tool, which can be processed on the machine tool During the procedure (i.e. online), simulation is performed according to the actual processing related parameters to avoid wasting processing time and cost and to improve product yield.

在一些實施例中，程式更包含加工程式碼，當CNC控制器執行加工程式碼時，控制工具機繼續加工程序，等待互動程式碼位於加工程式碼之前。 In some embodiments, the program further includes processing program code.

在一些實施例中，確認操作更包含比對此組加工相關參數與用以產生程式之模擬之參數。 In some embodiments, the confirmation operation further includes comparing the set of processing-related parameters with the simulation parameters used to generate the program.

在一些實施例中，加工方法更包含：若確認操作之結果不符合放行條件，則藉由電腦發送警告訊號，警告訊號包含聲音、影像、傳送至CNC控制器之停止執行指令、或其任意組合。 In some embodiments, the processing method further includes: if the result of the confirmation operation does not meet the release conditions, sending a warning signal by the computer, the warning signal includes sound, image, a stop execution command sent to the CNC controller, or any combination thereof .

在一些實施例中，加工方法更包含：在暫停加工程序期間，CNC控制器將啟動資訊寫入第一狀態參數中；在暫停加工程序期間，當電腦讀取具有啟動資訊之第一狀態參數時，電腦取得CNC控制器之該組加工相關參數並進行確認操作；若確認操作之結果符合放行條件，則電腦經由放行訊號將放行資訊寫入第二狀態參數；及當CNC控制器讀取具有放行資訊之第二狀態參數時，CNC控制器控制工具機繼續加工程序。上述內容涵蓋在電腦與CNC控制器的等待互動操作。一面，電腦等待CNC控制器將啟動資訊寫入第一狀態參數；另一面，CNC控制器等待電腦將放行資訊及/或停止執行資訊寫入第二狀態參數。藉此，可達到電腦與CNC控制器的互動。 In some embodiments, the processing method further includes: during the pause of the processing procedure, the CNC controller writes the start information into the first state parameter; during the pause of the processing procedure, when the computer reads the first state parameter with the start information , The computer obtains the processing related parameters of the CNC controller and performs the confirmation operation; if the result of the confirmation operation meets the release conditions, the computer writes the release information into the second state parameter through the release signal; and when the CNC controller reads the release When the second state parameter of the information, the CNC controller controls the machine tool to continue the processing procedure. The above content covers the waiting interactive operation between the computer and the CNC controller. On the one hand, the computer waits for the CNC controller to write the startup information into the first state parameter; on the other hand, the CNC controller waits for the computer to write the release information and/or stop execution information into the second state parameter. In this way, the interaction between the computer and the CNC controller can be achieved.

圖1為本揭露一實施例之加工系統1的方塊示意圖。如圖1所示，加工系統1包含電腦11、CNC控制器12以及工具機13。其中，電腦11與CNC控制器12耦接，例如是藉由有線連接或無線連接、或藉由區域網路(local network)或網際網路(Internet)而耦接。藉由相互耦接，電腦11與CNC控制器12可互傳訊號。本實施例不限制電腦11的實施態樣，其例如可包含所需硬體及軟體。CNC控制器12又與工具機13耦接，以控制工具機13。CNC控制器12藉由執行程式而控制工具機13進行各樣所需加工，例如切削加工。加工所需要設定的參數可由電腦11傳送至CNC控制器12或是由操作人員直接在CNC控制器12上設定。本實施例不限制工具機13的實施態樣，其可例如為車床、銑床、磨床、鑽床、沖床等。 FIG. 1 is a block diagram of a processing system 1 according to an embodiment of the disclosure. As shown in FIG. 1, the processing system 1 includes a computer 11, a CNC controller 12 and a machine tool 13. Among them, the computer 11 and the CNC controller 12 are coupled, for example, through a wired connection or a wireless connection, or through a local network (local network) or the Internet (Internet). By being mutually coupled, the computer 11 and the CNC controller 12 can transmit signals to each other. This embodiment does not limit the implementation of the computer 11, which may include required hardware and software, for example. The CNC controller 12 is coupled to the machine tool 13 to control the machine tool 13. The CNC controller 12 controls the machine tool 13 to perform various required processing, such as cutting processing, by executing programs. The parameters required for processing can be transmitted to the CNC controller 12 by the computer 11 or directly set on the CNC controller 12 by the operator. This embodiment does not limit the implementation aspect of the machine tool 13, which may be, for example, a lathe, a milling machine, a grinding machine, a drilling machine, a punching machine, and the like.

圖2為本揭露一實施例之在啟動工具機13之後進行模擬確認之加工方法的流程示意圖。請參照圖1及圖2以說明本實施例之加工方法。進行步驟S01以設置程式於CNC控制器12中，且程式具有等待互動程式碼。舉例來說，可藉由電腦11將程式傳送給CNC控制器12。當然，在其他實施例中，可由作業人員以手動方式將程式安裝於CNC控制器12中。特別的是，本揭露的程式具有等待互動程式碼。一般而言，上述的程式可利用客製化CAD/CAM軟體來產生。在一實施例中，在利用軟體進行切削模擬初步確認無問題而產生程式後，可將等待互動程式碼***程式中，再將具有等待互動程式碼的程式設置於CNC控制器12中，但需注意的是，在進行上述切削模擬時，設定的參數通常不完整或不完全準確，所以就需要本揭露之進行模擬確認的加工方法。 2 is a schematic flowchart of a processing method for performing simulation confirmation after starting the machine tool 13 according to an embodiment of the disclosure. Please refer to FIG. 1 and FIG. 2 to illustrate the processing method of this embodiment. Step S01 is performed to set the program in the CNC controller 12, and the program has a waiting interactive program code. For example, the computer 11 can send the program to the CNC controller 12. Of course, in other embodiments, the operator can manually install the program in the CNC controller 12. In particular, the program disclosed in this disclosure has a waiting interaction code. Generally speaking, the above-mentioned programs can be generated using customized CAD/CAM software. In one embodiment, after the software is used for cutting simulation to initially confirm that there is no problem and the program is generated, the waiting interactive code can be inserted into the program, and then the program with the waiting interactive code can be set in the CNC controller 12. It should be noted that during the above-mentioned cutting simulation, the set parameters are usually incomplete or incompletely accurate, so the processing method for simulation confirmation in this disclosure is required.

進行步驟S02以啟動工具機13，以使工具機13依據程式進行加工程序。舉例來說，可由操作人員按下CNC控制器12的CYCLE START按鍵來啟動工具機13。在其他實施例中，可藉由電腦11傳送啟動訊號以啟動工具機13。 Step S02 is performed to start the machine tool 13 so that the machine tool 13 performs processing procedures according to the program. For example, the operator can press the CYCLE START button of the CNC controller 12 to start the machine tool 13. In other embodiments, the computer 11 can send an activation signal to activate the machine tool 13.

進行步驟S03，在進行加工程序期間，當CNC控制器12執行等待互動程式碼時，則暫時停止工具機13，以暫停加工程序。 Step S03 is performed. During the processing procedure, when the CNC controller 12 executes the waiting interactive program code, the machine tool 13 is temporarily stopped to suspend the processing procedure.

進行步驟S04以在暫停加工程序期間，藉由電腦11取得CNC控制器12之一組加工相關參數。加工相關參數例如包含程式零點、機器零點、刀具長度補正、刀具直徑補正、加工參數(例如轉速、轉速百分比、進給速率、進給速率百分比等)、工具機13之構型與組態資料、或其任意組合等。在一實施例中，電腦11亦可下載CNC控制器12接下來要執行的程式部分，以進行後續的模擬。 Step S04 is performed to obtain a set of processing related parameters of the CNC controller 12 through the computer 11 during the pause of the processing program. Processing related parameters such as program zero point, machine zero point, tool length compensation, tool diameter Compensation, processing parameters (such as rotation speed, rotation speed percentage, feed rate, feed rate percentage, etc.), configuration and configuration data of the machine tool 13, or any combination thereof. In one embodiment, the computer 11 can also download the program part to be executed next by the CNC controller 12 for subsequent simulation.

進行步驟S05以藉由電腦11利用加工相關參數進行確認操作，確認操作包含根據加工相關參數和程式進行模擬，而預測出若工具機13繼續進行加工程序時是否會發生異常，以獲得確認操作之結果。模擬例如包含切削模擬、碰撞偵測、刀具路徑模擬、待切削零件之幾何形狀確認等等。 Step S05 is performed to use the computer 11 to use the processing-related parameters to perform the confirmation operation. The confirmation operation includes simulation based on the processing-related parameters and programs, and predict whether an abnormality will occur if the machine tool 13 continues to perform the processing procedure, so as to obtain the confirmation operation result. The simulation includes cutting simulation, collision detection, tool path simulation, geometric shape confirmation of parts to be cut, etc.

在一實施例中，程式中除了等待互動程式碼以外的部分是利用軟體進行參數設定以及模擬而得到，例如是刀具路徑模擬、切削模擬等。而本揭露實施例的確認操作可更包含比對上述設定的參數與本揭露的加工相關參數，以獲得確認操作的結果之一。亦即，在進行本揭露實施例的確認操作的模擬之前，可先比對實際的加工相關參數與先前用以產生程式之模擬的參數。 In one embodiment, the part of the program other than waiting for the interactive code is obtained by using software for parameter setting and simulation, such as tool path simulation, cutting simulation, etc. The confirmation operation of the embodiment of the present disclosure may further include comparing the above set parameters with the processing-related parameters of the present disclosure to obtain one of the results of the confirmation operation. That is, before performing the simulation of the confirmation operation in the embodiment of the present disclosure, the actual processing-related parameters can be compared with the previous simulation parameters used to generate the program.

進行步驟S06以判斷確認操作的結果是否符合放行條件，若結果為是，則進行步驟S07以藉由電腦11傳送放行訊號給CNC控制器12，以使CNC控制器12控制工具機13繼續加工程序。其中，放行訊號可包含繼續執行的指令或資訊。若確認操作的結果不符合放行條件，則進行步驟S08以藉由電腦11發送警告訊號，警告訊號例如包含聲音、影像、傳送至CNC控制器12之停止執行指令、或其一組合。其中，確認操作的結果不符合放行條件的狀況例如包含偵測到碰撞、剩餘刀具壽命不足、或切削過程中的切削力過大等等。 Go to step S06 to determine whether the result of the confirmation operation meets the release conditions, if the result is yes, go to step S07 to send the release signal to the CNC controller 12 through the computer 11, so that the CNC controller 12 controls the machine tool 13 to continue the processing procedure . Among them, the release signal may include instructions or information to continue execution. If the result of the confirmed operation does not meet the release conditions, step S08 is performed to send a warning signal through the computer 11, the warning signal including, for example, sound, image, a stop execution command sent to the CNC controller 12, or a combination thereof. Among them, the condition that the result of the confirmation operation does not meet the release conditions includes detection To collision, insufficient remaining tool life, or excessive cutting force during cutting, etc.

在實務上，本揭露的加工方法及加工系統可提供防呆功能。以刀具為例來說，可能現場操作人員裝錯刀具，此時本揭露的加工方法就能抓出錯誤。在應用上，本揭露的加工方法可以實施於第一個待加工工件即可，當確認無誤時，之後的工件就不需要等待互動程式碼的執行了。 In practice, the processing method and processing system disclosed in this disclosure can provide foolproof functions. Take the tool as an example, it is possible that the on-site operator installs the wrong tool, and the processing method disclosed in this case can catch the error. In terms of application, the processing method disclosed in the present disclosure can be implemented on the first workpiece to be processed. When it is confirmed that it is correct, the subsequent workpieces do not need to wait for the execution of the interactive code.

需注意的是，本揭露是在工具機13暫停的期間來進行模擬確認。倘若不是在工具機13暫停的期間來進行模擬確認，而是在工具機13進行加工程序的同時，電腦亦進行模擬確認，此種情況下，若於執行實際切削過程一段時間之後，才偵測到問題，例如偵測到有碰撞情形，將浪費加工時間、成本以及刀具等。 It should be noted that this disclosure is to perform simulation confirmation during the pause of the machine tool 13. If the simulation confirmation is not performed during the pause of the machine tool 13, but while the machine tool 13 is performing the processing procedure, the computer also performs the simulation confirmation. In this case, the detection will only be performed after the actual cutting process is executed for a period of time. When it comes to problems, such as detecting a collision, it will waste processing time, cost and tools.

圖3為本揭露一實施例之程式與加工程序對應的示意圖。如圖3所示，CNC控制器12所執行的程式30係使工具機13進行加工程序20，因此程式30係對應加工程序20。程式30包含等待互動程式碼31以及加工程式碼32。當CNC控制器12執行到等待互動程式碼31時，暫時停止工具機13以暫停加工程序，亦即使加工程序20進入等待互動操作21，此時電腦11可利用實際的加工相關參數及加工程式碼32進行確認操作之模擬。當CNC控制器12執行加工程式碼32時，控制工具機13繼續加工程序20，亦即使加工程序20進入加工操作22。 3 is a schematic diagram showing the correspondence between the program and the processing procedure of an embodiment of the disclosure. As shown in FIG. 3, the program 30 executed by the CNC controller 12 causes the machine tool 13 to perform the machining program 20, so the program 30 corresponds to the machining program 20. The program 30 includes a waiting interactive program code 31 and a processing program code 32. When the CNC controller 12 executes to wait for the interactive program code 31, it temporarily stops the machine tool 13 to suspend the processing procedure. Even if the processing program 20 enters the wait for interactive operation 21, the computer 11 can use the actual processing related parameters and processing program codes. 32 Perform the simulation of the confirmation operation. When the CNC controller 12 executes the processing program code 32, the machine tool 13 is controlled to continue the processing program 20, even if the processing program 20 enters the processing operation 22.

在本實施例中，等待互動程式碼31位於加工程式碼32之前，或者說等待互動操作21在加工操作22之前。另外，在其他實施例中，等待互動程式碼31可位於加工程式碼32之一適當位置。在本實施例中，舉例來說，等待互動程式碼31是位於程式30的最前面，使得在整個加工程序20的一開始就是等待互動操作21。另外，在其他實施例中，程式30可更包含另一等待互動程式碼33，等待互動程式碼33位於加工程式碼32之中，並可用以監測加工程序20。舉例來說，當加工程序20的加工操作22進行到某一階段時，可藉由等待互動程式碼33來暫停加工程序20，亦即使加工程序20進入另一等待互動操作23，使得電腦11可取得CNC控制器12之相關參數來進行監測。 In this embodiment, the waiting interactive program code 31 is located before the processing program code 32, or the waiting interactive operation 21 is before the processing operation 22. In addition, in other embodiments, the waiting interaction program code 31 may be located in an appropriate position of the processing program code 32. In this embodiment, for example, the waiting interactive program code 31 is located at the forefront of the program 30, so that the interactive operation 21 is waiting at the beginning of the entire processing program 20. In addition, in other embodiments, the program 30 may further include another waiting interactive program code 33. The waiting interactive program code 33 is located in the processing program code 32 and can be used to monitor the processing program 20. For example, when the processing operation 22 of the processing program 20 reaches a certain stage, the processing program 20 can be paused by waiting for the interactive code 33, even if the processing program 20 enters another waiting interactive operation 23, so that the computer 11 can Obtain the relevant parameters of the CNC controller 12 for monitoring.

圖4為本揭露一實施例之利用兩狀態參數來達成電腦11與CNC控制器12之等待互動操作21的雙向溝通的示意圖。如圖4所示，在本實施例中，第一狀態參數SP1與第二狀態參數SP2例如是CNC控制器12可控制之複數個參數的其中二者。在操作上，在暫停加工程序期間，CNC控制器12可將啟動資訊寫入第一狀態參數中。在暫停加工程序期間，當電腦11讀取具有啟動資訊的第一狀態參數SP1時，表示CNC控制器12已啟動(CYCLE START)工具機13且已暫時停止工具機13，因此電腦11可取得CNC控制器12之加工相關參數並進行確認操作。若確認操作之結果符合放行條件，則電腦11經由傳送給CNC控制器12的放行訊號而將放行資訊寫入第二狀態參數SP2。當CNC控制器12讀取具有放行資訊之第二狀態參數SP2時，表示工具機13可繼續加工程序，因此CNC控制器12控制工具機13繼續加工程序。總括來說，CNC控制器12可將資訊寫入第一狀態參數SP1並可讀取第二狀態參數SP2，而電腦可讀取第一狀態參數SP1並可將資訊寫入第二狀態參數SP2，藉此可達成電腦11與CNC控制器12的雙向溝通。上述內容涵蓋在電腦11與CNC控制器12的等待互動操作中。一面，電腦11等待CNC控制器12將啟動資訊寫入第一狀態參數SP1；另一面，CNC控制器12等待電腦11將放行資訊及/或停止執行資訊寫入第二狀態參數SP2。藉此，可達到電腦11與CNC控制器12的互動。 FIG. 4 is a schematic diagram showing the use of two state parameters to achieve a two-way communication between the computer 11 and the CNC controller 12 waiting for an interactive operation 21 according to an embodiment of the disclosure. As shown in FIG. 4, in this embodiment, the first state parameter SP1 and the second state parameter SP2 are, for example, two of a plurality of parameters controllable by the CNC controller 12. In operation, during the pause of the processing procedure, the CNC controller 12 can write the startup information into the first state parameter. During the pause of the machining process, when the computer 11 reads the first state parameter SP1 with start information, it means that the CNC controller 12 has started (CYCLE START) the machine tool 13 and has temporarily stopped the machine tool 13, so the computer 11 can obtain the CNC The controller 12 processes related parameters and performs confirmation operations. If it is confirmed that the result of the operation meets the release conditions, the computer 11 writes the release information into the second state parameter SP2 via the release signal sent to the CNC controller 12. When CNC controller 12 reads When there is the second state parameter SP2 of the release information, it indicates that the machine tool 13 can continue the machining process, so the CNC controller 12 controls the machine tool 13 to continue the machining process. In summary, the CNC controller 12 can write information into the first state parameter SP1 and can read the second state parameter SP2, and the computer can read the first state parameter SP1 and can write information into the second state parameter SP2. In this way, two-way communication between the computer 11 and the CNC controller 12 can be achieved. The above content is covered in the waiting interactive operation of the computer 11 and the CNC controller 12. On the one hand, the computer 11 waits for the CNC controller 12 to write the startup information into the first state parameter SP1; on the other hand, the CNC controller 12 waits for the computer 11 to write the release information and/or stop execution information into the second state parameter SP2. In this way, the interaction between the computer 11 and the CNC controller 12 can be achieved.

圖5為本揭露一實施例之在啟動工具機之後進行模擬確認的加工方法的應用示意圖。如圖5所示，首先，在CNC控制器12端，讓工具機13正常作業(步驟201)，然後按下CYCLE START按鍵(步驟202)以使工具機13進行實際的切削加工，即上述的加工程序20。接著，當CNC控制器12執行到***的等待互動程式碼時，暫停工具機13(步驟203)。此時，電腦11透過網路與CNC控制器12連線並讀取其狀態(步驟204)，並判斷CNC控制器12是否處於CYCLE START(步驟205)，這可例如由上述第一狀態參數SP1達成。若是，則由電腦11讀取CNC控制器12的加工相關參數(步驟206)，亦可從CNC控制器12下載程式或是以電腦原有的程式來進行模擬。然後，判斷模擬結果是否正常(步驟207)。若是，則由電腦11傳送繼續執行指令給CNC控制器12(步驟208)，並透過網路傳送指令給CNC控制器12(步驟209)，這可例如由上述第二狀態參數SP2達成。若否，則由電腦11傳送停止執行指令給CNC控制器12(步驟210)。此時，CNC控制器12等待電腦11所傳送的指令以判斷是否繼續之前暫停的加工程序(步驟211)。若是，則繼續加工程序(步驟212)。 FIG. 5 is an application schematic diagram of a processing method for performing simulation confirmation after starting the machine tool according to an embodiment of the disclosure. As shown in Figure 5, first, at the CNC controller 12 side, let the machine tool 13 work normally (step 201), and then press the CYCLE START button (step 202) to make the machine tool 13 perform the actual cutting process, that is, the above-mentioned Processing program 20. Next, when the CNC controller 12 executes the inserted waiting interactive code, the machine tool 13 is suspended (step 203). At this time, the computer 11 connects to the CNC controller 12 through the network and reads its status (step 204), and determines whether the CNC controller 12 is in CYCLE START (step 205). This can be determined by the aforementioned first status parameter SP1, for example. Reached. If yes, the computer 11 reads the processing-related parameters of the CNC controller 12 (step 206), or downloads the program from the CNC controller 12 or simulates the original computer program. Then, it is judged whether the simulation result is normal (step 207). If yes, the computer 11 will send the instruction to continue execution to CNC control The controller 12 (step 208), and sends commands to the CNC controller 12 via the network (step 209), which can be achieved, for example, by the aforementioned second state parameter SP2. If not, the computer 11 sends a stop execution instruction to the CNC controller 12 (step 210). At this time, the CNC controller 12 waits for the instruction sent by the computer 11 to determine whether to continue the previously suspended machining program (step 211). If yes, continue the processing procedure (step 212).
