工件

The high-precision sixteen keys spline broach was developed and further improvement was made,too.

被加工工件——滑动叉，是薄壁件，规格小、花键长度长、容易产生变形，键宽公差要求严格，在设计上、加工上难度非常大，因此设计了高精度十六键花键拉刀，并进一步改进。

It according to rotates divides into the positive rotation for the direction and the semi finished materials material flow direction similarities and differences and instead turns on lathe, including turns on lathe, the stable spinning and finally turns on lathe three stages.

其按旋轮进给方向与毛坯材料流动方向的异同分为正旋和反旋，包括起旋、稳定旋压和终旋3个阶段，成形中的工件可划分为3个区域，即未成形区、成形区和已成形区，材料所受到的应力、应变在不同阶段也具有不同的特点。

CNC lathe spindle speed due to very high, for ease of workpiece clamping, multi-use high-speed hydraulic power chuck, because it is in the production plant has passed a strict balance, with a high speed (speed limit up to 4000 ~ 6000r/min), high clamping force (push pull for the largest 2000 ~ 8000N), high-precision, adjusting claw convenience, through-hole, long life and so on.

由于数控车床主轴转速极高，为便于工件夹紧，多采用液压高速动力卡盘，因它在生产厂已通过了严格的平衡，具有高转速（极限转速可达4000~6000r/min）、高夹紧力（最大推拉力为2000~8000N）、高精度、调爪方便、通孔、使用寿命长等优点。

The basic working principle for the use of mobile thin metal wire to make electrodes, to carry out work on the pulse spark discharge in addition to metal corrosion, cut into type.

其基本工作原理是利用连续移动的细金属丝作电极，对工件进行脉冲火花放电蚀除金属、切割成型。

My company's small precision CNC lathes to medium and small-diameter shaft parts for the purpose of turning to high-precision, high-speed precision machining to the latest demand.

我公司的小型精密数控车床以中、小直径盘轴类工件的车削为目的，以高精度、高速度适应最新的精密加工需求。

The sine bar is coordinates the use gage block according to the sine principle composition standard angle, with by compares the way survey work piece angle and the inside and outside cone's one kind of precise quantity meter in the horizontal direction according to the elemental error.

正弦规是配合使用量块按正弦原理组成标准角，用以在水平方向按微差比较方式测量工件角度和内、外锥体的一种精密量仪。

In addition, the deflection of workpiece using machine strategy of cutting from both sides were smaller than that of cutting from one side.

采用在线摄影的方法，观察记录了石墨薄壁件高速铣削的加工工件断裂过程。

The influence of the welding parameters such as angular velocity of the pin, the radii of the pin and the shoulder, the cone angle, the screw-thread angle, etc., are studied in detail.

文章建立了搅拌摩擦焊接过程的三维有限元热分析模型，讨论了旋转速度、搅拌头半径、轴肩半径、搅拌针锥角以及螺纹角等焊接参数对工件温度场的影响。

The lathe dog which drives the work tends to produce a shearing force.

切削工具向工件所施加的压力产生了拉伸、压缩以及剪力作用。

Blanking, shearing and cutting tools perform their work by some form of "shearing" of cutting action. They include cut-off and shearing dies, blanking dies, piercing, shaving, notching, edging, and trimming tools. The last are applied to the forming of contour by a series of strokes.

落料、冲裁、切断工具都是以某种切断的&剪切&方式进行工作，有切断和冲裁模、落料模及冲孔、精冲、切口、切边、整修等工具，而整修模是通过一系列的冲裁来形成工件的轮廓。

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。
