It is not perfect to select the parameter system whose key parameter is unconfined compressive strength.

选择以单轴抗压强度为核心的参数系统作为刀具设计依据是不完善的。

Moreover, the differentiation of radius of mills over vertical axis is presented for determining undeformed chip thickness along any feeding direction.

其次根据数控环境下确定任意方向进给时瞬时切削厚度的需要，还导出了任意廓形刀具半径关于刀轴的变化率，进而为建立广义铣削力模型奠定了基础。

Using the principles of transformation matrix and vector operation, the trajectory equation of cutting edge relative to workpiece is derived.

摘 要：运用图形矩阵变换原理和矢量运算法则，推导出了立铣刀周铣过程中刀具切削刃上任意点相对于工件运动的轨迹方程，在此基础上构造出一种基于工件网格划分的三维表面形貌仿真算法，并给出了相应的仿真算例。

Except for research and discuss on turning and milling gray cast iron under high cutting speed, only few studies about machining nodular cast iron and vermicular cast iron with PCBN tool were carried out, while the two materials are widely used in manufacturing, specially automobile, aviation and machine tool. Therefore how to cutting these hard-to-machine materials economically and effectively is becoming an urgent-to-solve problem.

但是对于铸铁加工领域的研究则相对较少，除了对高速切削和铣削灰铸铁有较为深入的研究探讨外，关于PCBN刀具对球墨铸铁、蠕墨铸铁等材料加工应用的研究却很少，而这两种材料近些年已经大量的应用于汽车、航空、机床等制造业中，因此如何经济有效的加工这样难加工材料成为迫切需要解决的问题。

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。
