數(shù)控機(jī)床由輸入、輸出裝置、數(shù)控裝置、可編程控制器、伺服系統(tǒng)、檢測(cè)反饋裝置和機(jī)床主機(jī)等組成。
輸入裝置可將不同加工信息傳遞于計(jì)算機(jī)。在數(shù)控機(jī)床產(chǎn)生的初期，輸入裝置為穿孔紙帶，現(xiàn)已趨于淘汰;目前，使用鍵盤(pán)、磁盤(pán)等，大大方便了信息輸入工作。輸出指輸出內(nèi)部工作參數(shù)(含機(jī)床正常、理想工作狀態(tài)下的原始參數(shù)，故障診斷參數(shù)等)，一般在機(jī)床剛工作狀態(tài)需輸出這些參數(shù)作記錄保存，待工作一段時(shí)間后，再將輸出與原始資料作比較、對(duì)照，可幫助判斷機(jī)床工作是否維持正常。數(shù)控裝置是數(shù)控機(jī)床的核心與主導(dǎo)，完成所有加工數(shù)據(jù)的處理、計(jì)算工作，終實(shí)現(xiàn)數(shù)控機(jī)床各功能的指揮工作。它包含微計(jì)算機(jī)的電路，各種接口電路、CRT顯示器等硬件及相應(yīng)的軟件?？删幊炭刂破鲗?duì)主軸單元實(shí)現(xiàn)控制，將程序中的轉(zhuǎn)速指令進(jìn)行處理而控制主軸轉(zhuǎn)速;管理刀庫(kù)，進(jìn)行自動(dòng)刀具交換、選刀方式、刀具累計(jì)使用次數(shù)、刀具剩余壽命及刀具刃磨次數(shù)等管理;控制主軸正反轉(zhuǎn)和停止、準(zhǔn)停、切削液開(kāi)關(guān)、卡盤(pán)夾緊松開(kāi)、機(jī)械手取送刀等動(dòng)作;還對(duì)機(jī)床外部開(kāi)關(guān)(行程開(kāi)關(guān)、壓力開(kāi)關(guān)、溫控開(kāi)關(guān)等)進(jìn)行控制;對(duì)輸出信號(hào)(刀庫(kù)、機(jī)械手、回轉(zhuǎn)工作臺(tái)等)進(jìn)行控制。檢測(cè)反饋裝置由檢測(cè)元件和相應(yīng)的電路組成，主要是檢測(cè)速度和位移，并將信息反饋于數(shù)控裝置，實(shí)現(xiàn)閉環(huán)控制以保證數(shù)控機(jī)床加工精度。
數(shù)控加工的準(zhǔn)備過(guò)程較復(fù)雜，內(nèi)容多，含對(duì)零件的結(jié)構(gòu)認(rèn)識(shí)、工藝分析、工藝方案的制訂、加工程序編制、選用工裝及使用方法等。機(jī)床的調(diào)整主要包括刀具命名、調(diào)入刀庫(kù)、工件安裝、對(duì)刀、測(cè)量刀位、機(jī)床各部位狀態(tài)等多項(xiàng)工作內(nèi)容。程序調(diào)試主要是對(duì)程序本身的邏輯問(wèn)題及其設(shè)計(jì)合理性進(jìn)行檢查和調(diào)整。試切加工則是對(duì)零件加工設(shè)計(jì)方案進(jìn)行動(dòng)態(tài)下的考察，而整個(gè)過(guò)程均需在前一步實(shí)現(xiàn)后的結(jié)果評(píng)價(jià)后再作后一步工作。試切成功后方可對(duì)零件進(jìn)行正式加工，并對(duì)加工后的零件進(jìn)行結(jié)果檢測(cè)。前三步工作均為待機(jī)時(shí)間，為提高工作效率，希望待機(jī)時(shí)間越短越好，越有利于機(jī)床合理使用。該項(xiàng)指標(biāo)直接影響對(duì)機(jī)床利用率的評(píng)價(jià)(即機(jī)床實(shí)動(dòng)率)。
三、機(jī)床數(shù)控系統(tǒng)需要解決的幾個(gè)問(wèn)題
機(jī)床是由機(jī)械和電氣兩部分組成，在設(shè)計(jì)總體方案時(shí)應(yīng)從機(jī)電兩方面來(lái)考慮機(jī)床各種功能的實(shí)施 The motors control the nozzles to swing back and forth. Therefore, the whole etching part is composed of 12 motors. Because the motor keeps swinging back and forth, it is called swing motor here.
1.2 introduction to swing motor movement according to the process requirements, the motor must operate according to a certain trajectory, and different motor operation trajectories are different. Due to the high requirements for the running curve, the B & R PCC and acopos servo controller are selected for the control of the swing motor. On the upper computer, the staff gives 16 points on a track, as shown in Fig. 2, where the horizontal axis is the position and the vertical axis is the speed. Each of the 12 Motors has a set curve. In addition to completing the logic control of starting, stopping and running of the motor, the main function of PCC is to control the motor to move according to a certain trajectory, so that the trajectory passes through the set 16 points at the same time, and ensure the smooth operation of the motor. Due to the requirement of fast response and high control accuracy, the swing part uses synchronous servo motor for motion control. Before using the PLC of Toshiba company, there was a problem of uneven swing, so the high-performance controller PCC developed by B & R was used. PCC uses embedded operating system in the controller, and the device layer network uses real-time Ethernet, which can achieve very high real-time control requirements. The swing part adopts B & R 2005. The 2005 Series CPU is the fourth generation control system SG4 of B & R, and the Intel processor is adopted, including power module, CPU module and digital input / output module. A power link network adapter is inserted into the PCI bus slot of the CPU. If Powerlink is used in series, at most 10 servo controllers can be connected in series. The system uses power link if786 and one hub to divide 12 motors into two series branches for real-time control.
