摘  要
組合機(jī)床及其自動(dòng)線是集機(jī)電于一體的綜合自動(dòng)化程度較高的制造技術(shù)和成套工藝裝備。它的特征是高效、高質(zhì)、經(jīng)濟(jì)實(shí)用，因而被廣泛應(yīng)用于工程機(jī)械、交通、能源、軍工、輕工、家電等行業(yè)。我國傳統(tǒng)的組合機(jī)床及組合機(jī)床自動(dòng)線主要采用機(jī)、電、氣、液壓控制，它的加工對(duì)象主要是生產(chǎn)批量比較大的大中型箱體類和軸類零件，完成鉆孔、擴(kuò)孔、鉸孔，加工各種螺紋、鏜孔、車端面和凸臺(tái)，在孔內(nèi)鏜各種形狀槽，以及銑削平面和成形面等。隨著技術(shù)的不斷進(jìn)步，一種新型的組合機(jī)床——柔性組合機(jī)床越來越受到人們的青睞，它應(yīng)用多位主軸箱、可換主軸箱、編碼隨行夾具和刀具的自動(dòng)更換，配以可編程序控制器（PLC）、數(shù)字控制（NC）等，能任意改變工作循環(huán)控制和驅(qū)動(dòng)系統(tǒng)，并能靈活適應(yīng)多品種加工的可調(diào)可變的組合機(jī)床。
本文對(duì)可編程序控制器（PLC）應(yīng)用于雙面鉆孔組合機(jī)床電氣控制系統(tǒng)的設(shè)計(jì)思想作了介紹。對(duì)系統(tǒng)的硬件組成和軟件設(shè)計(jì)作了較為詳細(xì)的闡述。通過上位計(jì)算機(jī)可對(duì)機(jī)床的現(xiàn)場(chǎng)狀態(tài)實(shí)施監(jiān)控和對(duì)工作參數(shù)進(jìn)行調(diào)整，使系統(tǒng)工作在最佳狀態(tài)。近幾年來的現(xiàn)場(chǎng)應(yīng)用情況表明，該P(yáng)LC控制系統(tǒng)工作可靠，操作方便，提高了工效。
關(guān)鍵詞：PLC；組合機(jī)床；步進(jìn)梯形指令(STL)。

Abstract
Combination machine tools and automatic line is a comprehensive collection and integration of high degree of automation in the manufacturing technology and process equipment packages. It is characterized by highly efficient, high quality, economical and practical, they have been widely used for mechanical engineering, communications, energy, industry, light industry, and home electrical appliances industry. Our traditional combination machine tools and machine tool portfolio automatically routes primarily use machines, electricity, gas, hydraulic control, and its processing is targeted at the production lot larger-and medium-bold type and Zhou Lei parts and complete drilling, reaming, cut Kong, the processing of thread, boring, cars carry noodles and protrude Taiwan in Conedera smooth-bore various shapes shafts and horizontal Xianxiao and shape face. As technology advances, a new portfolio of machine tools -- soft combination machine tools increasingly been favored, it applied a line box, convertible main boxes, coding and cutlery accompanying jig automatic replacement, coupled with programmable controller (PLC), numerical control (NC), to arbitrarily change the work cycle control and drive systems, and the flexibility to adapt to the multi-species processing scale variable portfolio tools.
    This article mainly introduces the design thought of PLC applying for Modular Machine Tool electronic control system. It gives a detailed statement on the components of the system hardware and design of software. detail. The machine tool state can be monitored and the parameter can be adjusted in the site by top-computer, and enabling the system to have optimal property. Recent application on spots shows: this PLC controlling system works reliably, operates conveniently and effectively.
Keywords: PLC； Modular Machine Tool；STL
