Since the equipment is vertical lathe, unlike PLC subroutine library in the lathe applications, it must address the specific conditions of the machine to amend PLC subroutine.數(shù)控系統(tǒng)的各個部件安裝連接完成后，開始調(diào)試 PLC控制程序。由于該設(shè)備是立式車床，不同于 PLC子程序庫中的車床應(yīng)用程序，所以必須針對該機床的具體情況修改 PLC子程序。Set the knife for B-axis, and the standard procedures only X and Z axis, and the need to increase the B-axis in the MCP plus or minus adding B-axis direction to move the button, the need for SBR34, SBR38, SBR40 such as subroutine. Because it is vertical lathe, X, Z-axis direction to move the plus or minus key MCP and set different standards also needs to be revised. According to MCP on the machine need to design user-defined keys, such as hydraulic launch, hydraulic stop, relax beams, and light beams locking design MCP and machine operator panels PLC control 外文資料翻譯8procedures and debugging features to achieve. Fully tested by the use of the subroutine library of subroutines to ensure that the subroutine with the functions of PLC control procedures linked, are correct. Alarm users edit PLC design, machine parameters provided by setting the properties of each alarm. Machine set basic parameters include: PROFIBUS bus configuration, positioning servo drive module, the spindle axis position control and coordinate enable ratio and transmission parameters.將刀庫設(shè)為 B軸，而原標(biāo)準(zhǔn)程序只有 X、Z 軸，需要增加 B軸和在 MCP上添加 B軸正負方向點動鍵，需要對 SBR34、SBR38、SBR40 等子程序。由于是立式車床，X、Z 軸正負方向點動鍵與 MCP標(biāo)準(zhǔn)設(shè)置不同也需要修改。根據(jù)機床需要設(shè)計 MCP上用戶自定義鍵，如液壓啟動、液壓停止、橫梁放松、橫梁鎖緊及指示燈，設(shè)計 MCP和機床操作面板的 PLC控制程序并且調(diào)試功能實現(xiàn)。全面測試所使用的子程序庫的子程序，確保子程序的功能在與 PLC控制程序聯(lián)結(jié)在一起時正確無誤。編輯設(shè)計 PLC用戶報警，通過設(shè)定機床參數(shù)規(guī)定每個報警的屬性。設(shè)定機床基本參數(shù)包括：PROFIBUS 總線配置、伺服驅(qū)動器模塊定位、主軸和坐標(biāo)軸位置控制使能以及傳動系統(tǒng)參數(shù)配比。In the machine undergone a series of adjustments, NC Machine Tools has basically can be in normal operation. But to make the whole system into the best running state, but also a system parameter optimization work. 在對機床進行了一系列調(diào)整后，數(shù)控機床已基本可以正常運行。但要使整個系統(tǒng)進入最佳運行狀態(tài)，還應(yīng)進行系統(tǒng)參數(shù)優(yōu)化等工作。when the normal operation of the system as a whole, should also coordinate axis corresponding parameters such as optimal adjustment, such as: speed, gain, and the acceleration of the control parameters, in order to enable access to the best system of the state. In the normal operation of machine tools, machine tools should also mechanical parts, such as the vertical axis, the reverse gap, transmission precision measurement adjustments, the mechanical system to the best. Of course, the mechanical adjustments, should also fine-tune system parameters to enable the machine running in the best condition. When the part of the adjustment after the end of the machine through mechanical precision measurement, CNC machine tools needed for the position control system for precision compensation. Reverse clearance 外文資料翻譯9compensation for position feedback encoder mounted on the lead screw drive-head, although the slowdown in bins eliminate mechanical part of the reverse gap, but the reverse itself leadscrew gap still exists, the value of the corresponding input system parameters, each reverse operation, the system of compensation. Because long-term use of the leadscrew wear, the location of the leadscrew pitch and will have a nominal value error, to improve positioning accuracy, the system parameters compensation.當(dāng)整個系統(tǒng)運行正常后，還應(yīng)對相應(yīng)的坐標(biāo)軸等參數(shù)優(yōu)化調(diào)整，如：速度、增益、加速度及各項監(jiān)控參數(shù)等，以使系統(tǒng)進入最佳工作狀態(tài)。在機床正常運行后，還應(yīng)對機床機械部分，如各軸垂直度、反向間隙、傳動系統(tǒng)精度等進行測量調(diào)整，使機械系統(tǒng)達到最佳。當(dāng)然，機械調(diào)整后，還應(yīng)對系統(tǒng)參數(shù)進行微調(diào)，以使機床運行在最佳狀態(tài)。當(dāng)各部分的調(diào)整結(jié)束后，通過對機床機械精度的測量，還需對數(shù)控機床的位控系統(tǒng)進行精度補償。反向間隙補償由于位置反饋編碼器裝在傳動絲杠的端頭，雖然消除了減速箱等機械傳動部分的反向間隙，但絲杠本身的反向間隙仍然存在，可將該值輸入系統(tǒng)相應(yīng)參數(shù)，每次反向運行時，系統(tǒng)自動補償。由于絲杠長期使用中的磨損，絲杠各位置的螺距與標(biāo)稱值會有一定誤差，為提高定位精度，通過系統(tǒng)參數(shù)進行補償。According to the production needs of users with the process of transforming machine tools, from SINUMERIK 802D CNC system for the analysis, design and implementation. At present, against the machine mechanical, electrical, various aspects of the system transformation, installation, commissioning work has been completed, samples were processed fully achieve the desired results. Machine Tool has been transformed into normal use, the progressive completion of a number of machining tasks. From the use of the machine running the state, the modified machine compared with the original machine, greatly enhancing the functionality, a high degree of automation. NC powerful features greatly broadened the scope of machining parts. Better guarantee the consistency of the parts processing, and product quality. At the same time a high degree of automation has greatly reduced the labor intensity operations workers, but in the operation of the overall quality of workers has also put forward higher requirements. 根據(jù)用戶生產(chǎn)的需求，結(jié)合機床改造過程，對由 SINUMERIK 802D數(shù)控系統(tǒng)進行了分析、設(shè)計及實施。目前，針對該機床的機械、電氣、系統(tǒng)各個方面的外文資料翻譯10改造、安裝、調(diào)試工作已經(jīng)完成，樣件加工完全達到預(yù)期效果。改造后機床已投入正常使用，陸續(xù)完成了多項零件加工任務(wù)。從整個機床的使用、運行狀態(tài)來看，改造后機床與原機床相比，功能的極大增強、自動化程度很高。 強大的數(shù)控功能極大地拓寬了機床加工零件的范圍。更好地保證了零件加工的一致性和產(chǎn)品質(zhì)量。同時高度的自動化也大大降低了操作工人的勞動強度，但對操作工人的綜合素質(zhì)又提出了更高的要求。From the machine operable, compact structure reasonable, displays, switches and indicator of the layout more suitable for the use of operators. At the same time increased by a small handheld unit operations, in order to operate in different state of the operation of a more appropriate choice of location. The hoisting of the entire operating system using TFT LCD, the window menu-operation, not only to reduce the operation buttons, but more simple and easy operation. 從機床的可操作性來看，結(jié)構(gòu)緊湊合理，顯示器、各種開關(guān)和指示燈布局更適合操作人員的使用。同時增加了一個小型的手持操作單元，以便于操作人員在不同的狀態(tài)下選擇更合適的操作位置。整個懸掛操作系統(tǒng)采用 TFT液晶顯示器，窗口菜單式操作方式，不但減少了操作按鈕，而且操作更為簡單容易。After transformation, the machine can be maintained and enhanced. NC system for monitoring the work of the state control components and fault and displayed on the monitor in a timely manner, while PLC control applications, so that the whole machine tool control systems greatly simplify the circuit. All this makes machine fault detection and maintenance more convenient and rapid. Secondly, the need to be tested, liquid injection, fuel components are arranged in operation or maintenance staff accessible areas, which will help the day-to-day maintenance. 改造后的機床增強了可維修性。數(shù)控系統(tǒng)可監(jiān)控各控制部件的工作狀態(tài)及故障，并及時在顯示器上顯示，同時 PLC控制的應(yīng)用，使整個機床控制系統(tǒng)線路大為簡化。所有這些都使機床故障檢測和維修更為方便、迅速。其次，需經(jīng)常進行檢測、注液、加油的部件均布置于操作或維修人員容易接近的地方，利于日常的保養(yǎng)維護。After transformation, the machine reliability greatly improved. NC system, servo control systems, such as the various components of the system are highly integrated computer control system, which makes the whole machine tool control system itself 外文資料翻譯11has a high reliability. Design and Application of PLC, succeeded in bringing all of the control to the harmonization greatly simplifies the machine control circuit and the necessary components, and more conducive to improving the reliability of the whole system. The completion of the machine tool, not only for users to expand the scope of the processing machine, but also save a lot of money. The success of this transformation for the future transformation of the machine has accumulated a wealth of experience.改造后的機床可靠性大為提高。數(shù)控系統(tǒng)、伺服系統(tǒng)等控制系統(tǒng)的各個組成部分均是高度集成的微機控制系統(tǒng)，這使得整個機床控制系統(tǒng)本身就具有較高的可靠性。PLC 的設(shè)計應(yīng)用，成功地使各個控制部分達到了協(xié)調(diào)統(tǒng)一，極大地簡化了機床控制線路及所需元器件，更有利于提高整個系統(tǒng)的可靠性。 該機床改造的完成，不但為用戶擴大了該機床的加工范圍，也節(jié)約了大筆資金。本次改造的成功也為今后的機床改造工作積累了大量的經(jīng)驗。
