According to the wire electrode on the trajectory of the different forms of control, WEDM can be divided into three types:* is a copy-control, cutting their lines in advance to create the shape of the workpiece and the same mode *, When the rough machining parts and die at the same time * Clamping in the machine tool table, in the process of cutting wire electrode tightly * close to the edge of model for mobile track, thus cutting out the model * with the same shape and precision to work; another One is the optical tracking control, the cutting in line before the first parts in accordance with drawings by a certain ratio of enlarge depicts an electro-optical tracking maps, drawings will be processed when the machine electro-optical tracking placed on the stage, followed on the stage The first photo has to follow the ink line graphics track movement, and then through the use of electrical, mechanical linkage to control the machine tool table work together with the relative electrode wire Xiang Sixing do sports in order to cut out the pattern and shape of the workpiece to the same; a re - Is a digital process control, advanced digital automatic control technology, machine-driven process in accordance with the geometry of the workpiece before the parameters of good pre-processing CNC automatic completion of the processing, production do not look like without drawing board also plans to enlarge, in front of more than two Control in the form of higher precision processing and broad scope of application, at home and abroad for more than 95% of WEDM have been using digital technology.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是*模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的*模，加工时把工件毛坯和*模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着*模边缘作轨迹移动，从而切割出与*模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95％以上的电火花线切割机床都已采用数控化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
