Three kinds of cutting material were selected to machine stainless steel machining experiment such as ceramic cutting tools, cermets cutting tools and coated carbide cutting tools, in which the best range of each kind of tool material was founded. For example, LT55 was suitable to be machine lCrl8Ni9Ti as the cutting speed surpasses 120m/min and have a good wearable property.(3) Surface roughness was measured under different cutting conditions. Feed rate played the most important role in impacting surface roughness, and then cutting speed.(4) Chip patterns in different cutting speed with various cutting materials were analyzed. With the increase of turning speed, chip became shorter and was easy to be broken. For instance, serration chip appeared in high sped turning stainless steel with LT55;(5) Work hardening of austenitic stainless steel was analyzed.

Dynamic cutting force is a basic parameter and it directly influences relative displacement between tool and workpiece, tool wear and surface quality in turning operation. Therefore, simulation model of dynamic cutting force is an important part of machining physical simulation research. Cutting force models commonly used are empiristic equations. These equations are often based on statistical analysis of machining data, obtained via changing one or more machining parameters, whilst fixing others. But a complete turning process and nature of force can not be accurately described by means of these models.

动态切削力是切削加工过程中的基本参数，其动态变化直接影响加工过程中刀具与工件的相对位移、刀具磨损和表面加工质量等，因此动态切削力的预测仿真建模是切削过程物理仿真研究的基础，但是目前大多使用经验公式描述动态切削力，这些经验公式多少存在一些不足，难以完全真实地反映在整个切削过程中力的变化历程和变化特点。

It is one of the most widely used methods to groove and disconnect the workpiece with the cutter,but in the process of cutting the movement of the cross-feed can reduce the working orthogonal clearance,which increases the friction between the tool flank of the cutting tool and the machined surface,and hence results in the break of the workpiece and the working tool.

用切断刀对被加工工件切断或切槽是生产中应用最广泛的加工方法之一，但在切削过程中横向进给运动的影响使刀具工作后角减小，加剧了刀具后刀面与加工表面之间的摩擦，从而会导致工件被挤断，刀具易折断。

As a result of cutting and high feed rate, HSC processing will normally be the life of the tool down paper, from the tool material, geometry parameters, stretching the length of the hanging, as well as cutting parameters and cutting geometry, cutting line, and other lubrication cooling to take measures to minimize the reduction of life expectancy.

由于切削和进给速度高，HSC加工中刀具的寿命一般会降纸，需要从刀具材料、几何参数、悬伸长度以及切削参数、切削几何关系、走刀路线、润滑冷却等各方面采取措施，尽可能减少寿命的降低。

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。
