工件

Structural modeling task is to produce some stable flat combination, Thus, these plane of the work pieces clamping force and will fixture stability.

结构造型任务就是要产生若干稳定平面的组合，这样在这些平面上的各夹紧力将使工件和夹具稳定。

Certain mold components (for example convex-concave mold) the shapeand the size by the product decided thus is unable in the moduledesign time foresees, therefore only can according to the common shapedesign module (for example circular or rectangular drift), is suitablethe surface to be narrow; Certain mold components (for example flush压模work piece localization components) although mutuallycoordinates to carry out some function, but their space arrangesdifficult to seek the rule and the general character, therefore evenif divides according to the function cannot have the module.

某些模具零件的形状和尺寸由产品决定因而无法在模块设计时预见到，所以只能按常见形状设计模块，适用面窄；某些模具零件（如冲压模的工件定位零件）虽然互相配合执行某一功能，但它们的空间布置难寻规律与共性，因此即使按功能划分也不能产生模块。

These are known as computer numerical control lathes and the too or the cross slide can be fed in any direction in the horizontal plane to generate a required contour on the workpiece.

这些车床称为计算机数字控制CNC）车床，而且刀具或横向滑板可以在水平面上的任一方向进给以使工件上产生所需的廓形。

Diameter work piece over the ways, but not over the carriage cross-feed slide.

直径工件超过途径，但不超过运载两岸饲料幻灯片。

Based on the foregoing results studied, two methods (by designing the cutting edge geometry and the new type compound cutting tool) are developed to applying machining to surface harden parts. And this approach will be alternative to conventional precision machining for the high-strength wear-resisting aluminums bronze.

在前述研究基础上，提出改变刀刃形状和设计复合刀具二种方法实现工件材料在切削加工的同时达到材料的表面强化，为高强耐磨铝青铜的精密加工提供了新的工艺路线。

To improve the cutting punch trough when the warping phenomenon

改善工件表面完整性，避免切削液电解发生软化层

While the material machined hardness is lower than HRC50, the changing rule of cutting force and cutting temperature was accordant with the common cutting theory.

当工件材料硬度低于HRC50，切削力和切削温度的变化规律符合普通的金属切削理论，硬度超过HRC50则切削力和切削温度的变化规律大不相同。

General clue of this paper is simulating wood stress field change in initial cutting stage and working out weighted boundary condition of cutting tools first,and then based on which, finding out shear stress and maximal effective stress when wood cut-ted.Meanwhile,finite element comparative analysis is proceeded on distortion and stress field by changing tool orthogonal rake.

本课题的总体思路是通过大型有限元软件ANSYS来模拟切削初始阶段中木材的应力场变化，进而得出刀具受力的边界条件，依此为基础求出木材受切时的剪应力及最大等效应力，同时通过变化刀具前角分别对受切工件的变形及应力场进行有限元比较分析，从而确定刀具的优化前角；优化前角确定后，再通过对刀具进行强度校核确定后角优化值。

In addition to the above reasons, the cutting speed is too slow, cutting torch and the workpiece vertical degrees, as well as the operator of the plasma cutting machine familiarity with the operational level, have affected the stability of the plasma arc, the user should pay attention in these areas .

除以上原因外，切割速度过慢，切割时割炬与工件的垂直度，以及操作者对等离子切割机的熟悉程度，操作水平等，都影响等离子弧的稳定性，使用者应在这些方面注意。

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.

交际能力和语法的关系应该是目标与途径的关系。
