刀具

Most of hob design for non-involute gears are nowadays taken by approximation method.For example,the normal sectional profile of hob worm therad is usually regarded approximately as its basic rack profile.Recently, some new methods have been developed in this respect but, perhaps, they appear overelaborate since the principle of spacing engagement is based on. For this reason , the paper offers a new design procedure for hob worm based on the planar engagement principle with the intention of simplific...

本文应用平面啮合原理精确设计各种非渐开线齿轮滚刀的基本蜗杆，提出并应用啮合线的投影原理从工件齿轮端截面的啮合线直接求得刀具蜗杆的端面齿形，而不必求出媒介齿条的齿形，方法很简单，还从啮合线的投影原理简明而形象地证明了一对螺旋齿轮直接啮合过程的啮合线是一条垂直于齿向的平面曲线。

节材铅笔在使用中与木制铅笔一样，使用过程中笔头的铅芯便粗，可用专用刀具修整，直致铅芯用完，笔头弃掉。

Error analysis In order to analysis the pose error of the hexapod machine tool, considering the characteristics of the parallel mechanism,"analysis on the error prominency factors for the hexapod machine tool pose error"is proposed. Numerically, the error prominency factor can express the influence on the pose error of the tool resulted from the mechanism parameter error within the whole workspace.

四、位姿误差分析为了定量地对并联机器人机床位姿误差进行分析，结合并联机构的特点，首次提出了&并联机器人机床位姿误差放大因子分析法&，因位姿误差放大因子是反映机床机构参数误差对刀具末端误差影响大小的机床工作空间内的统计值，因此既可作为机床结构参数精度设计的依据又可对机构参数进行优化。

It suggests guarantees that the toolpath of climb cutting can be obtained in consideration of the cutter location surface Zmap model features, thus to gain a qualitied surface.

该算法充分考虑了刀位面Zmap模型的特点，能确保刀具轨迹始终处于顺铣状态，从而保证了良好的加工工艺性。

The super slippy surface can be got after colored metal and non-metal is cut by single crystal diamond cutter. Following, it can take the place of super precision grinding, the efficiency can be increased, and the precision can be guaranteed.

使用精密的单晶金刚石刀具加工有色金属和非金属，能够直接切出超光滑的加工表面，这样就可以取代超精密磨削等精加工工序，极大的提高加工效率，同时也可以保证加工精度和加工表面质量。

Another cutting tool at sub-category there is technological innovation, can provide fully automatic slitting Quilting.

另在分切刀具类有技术创新，可提供全自动分切绗缝机。

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。
