摘 要隨著數(shù)控線切割機(jī)床應(yīng)用的不斷擴(kuò)大,機(jī)床本身也得到了不斷的發(fā)展。十多年前, “負(fù)旦型”數(shù)控線切割機(jī)床首先應(yīng)用于實(shí)際生產(chǎn),最早控制臺是由晶體管分離元件組裝而成,逐漸采用集成電路,現(xiàn)在正向采用微型計(jì)算機(jī)控制的方向發(fā)展,因此本論文設(shè)計(jì)的“電火花線切割機(jī)的電氣控制系統(tǒng)”是以 89C55 單片機(jī)作為控制核心,步進(jìn)電機(jī)作為驅(qū)動電機(jī),光柵作為位移檢測元件而構(gòu)成的一個閉環(huán)控制系統(tǒng)。電火花線切割機(jī)的核心技術(shù)就是控制位移量的精度。本文采用了 QH-200 型光柵尺傳感器來檢測位移量,通過 ATMEL 公司的 89C55 作為控制元件,輸出的兩路方波,送入單片機(jī),通過 CH250 來驅(qū)動電機(jī),控制電機(jī)移動,完成想要的工件圖形。本文設(shè)計(jì)的電火花電氣系統(tǒng),控制精度及檢測精度都能達(dá)到±0.01 毫米。系統(tǒng)具有加工狀態(tài)自動顯示功能,由鍵盤控制系統(tǒng)啟、停以及對位移量進(jìn)行設(shè)定。關(guān)鍵詞:電火花 線切割 單片機(jī) 步進(jìn)電機(jī)AbstractAlong with the numerical control line cutting engine bed application unceasing expansion, engine bed itself also arrived the unceasing development. More than ten years ago, “the negative day” the numerical control line cutting engine bed first applies and the actual production, starts the control bench is uses the transistor separative element assembly to become, after but uses the integrated circuit, now to is using the direction which the microcomputer controls to develop, Therefore this definition design “the electrical fire colored thread cutter automatic control” is by 8031 shrapnel machine took the control core, step-by-steps the electrical machinery achievement to actuate the electrical machinery, the diffraction grating a closed-loop control system which constitutes as the position examination part.WEDM the core technology is to control the accuracy of displacement. In this paper, the QH-200-foot grating sensors to detect displacement through ATMEL's 89C55 as a control device, the output of two-way square, into the microcontroller, through CH250 to drive motor, control motor movement, would like to complete To the workpiece graphics. In this paper, the design of the EDM electrical system, control accuracy and precision of detection to achieve ± 0.01MM. State system has automatically display processing functions from the keyboard control system Kai, stopped and the displacement of a set.KeyWord:electrical sparkle linear cutting microcomputer Stepper motor
