刀具

When this occurs, the tool should be reconditioned immediately.

一旦发生这种情况就应立即打磨刀具。

For the relieving shaped milling cutter with the traditional Archimedes back curve, the relief angle of each point on the cutting edge is changed after refacing the cutter.

传统的阿基米德螺线齿背的铲齿成形铣刀在重磨前刀面后，切削刃上各点的后角将发生变化，从而影响刀具切削性能的稳定。

All repositioning of the tool can be done automatically with minimum amount of tilt.

所有的刀具重定位都能够自动完成，且是在最小倾角值的条件下完成。

This paper introduces the software structure and real time process principle of real time NC system, according to the milling process character of NC system and the geometrical modeling method of computer simulation, presents a technique of subdividing roughcasts and data structures which applies to the computer simulation of the NC milling process; and in order to quicken the operating rate and enhance the reality of computer simulation, puts forward a logic algorithm of the 3D milling process of real time NC system which can display the effects of the computer simulation of 3D milling process of real time NC system dynamicly and efficiently in PC, such as the movement of tools, the elimination of materials, the shape changing of roughcasts.

刘景能，蒙艳玫（广西大学，530004）摘要：本文介绍了实时数控系统软件结构与实时工作原理，根据数控系统铣削加工的特点和计算机仿真几何建模方法，给出了适用于数控铣削加工仿真的毛坯离散细分方法和数据结构；为了加快处理速度和增强仿真效果真实感，提出了一种实时数控系统三维加工仿真的逻辑设计算法，即在单CPU机器单线程程序中使用普通软件循环和定时器模拟实现多线程，该算法可以在微机上动态显示高质量的铣削加工过程刀具的运动，材料的去除和毛坯形状的变化等数控加工三维仿真效果。

During the shift, knife must be washed and sanitized before and after each task.

在工作时，刀具必须在每件工作前和后，进行清洗和消毒。

Knife must be cleaned and sanitized and hung in designed sanitary station.

刀具必须加以清洁和消毒，并且存放在指定清洁的位置。

In addition,this fluid can prolong the service lives of cutting tools and grinding wheel,enhance their working efficiency,and decrease the surface roughness of the workpiece as well, instead of the traditional saponified oil and emulsion.

它是由防锈剂、抗磨剂、防腐剂和多种表面活性剂复配而成，具有优良的冷却润滑和清洗防锈能力，能延长刀具和砂轮的使用寿命，提高工件表面光洁度和工作效率，可代替传统的皂化油和乳化液。

The process of this technique is engraving various patterns with different knives on the finished lacquer base, and then filling in colors, covering with gold leaves and scattering pearl scraps according to the tableau. This technique can be divided into six technological processes, namely engraving, shovelling, smoothing, coloring, covering and scattering.

该工艺在制作好的漆坯件上，运用各种刀具刻出各类图案，并根据画面要求进行填色、贴金、撒螺屑等装饰手法，工艺流程可归纳为刻、铲、批、作、贴、撒六步。

"If you want to win a sprinting championship, you'll have to pull up your socks,"

在拉丁美洲，你不要送刀具，因为这会暗示你想要断绝关系。

His father and grandfather followed the occupation of stone-cutters or minor statuaries; and it is said that their family had for several ages supplied Passagno with members of that calling.

他的父亲和祖父其次是占领石刀具或轻微statuaries ；这是说，他们的家人已为几个年龄供应passagno成员认为要求。

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。
