Dynamic cutting force is a basic parameter and it directly influences relative displacement between tool and workpiece, tool wear and surface quality in turning operation. Therefore, simulation model of dynamic cutting force is an important part of machining physical simulation research. Cutting force models commonly used are empiristic equations. These equations are often based on statistical analysis of machining data, obtained via changing one or more machining parameters, whilst fixing others. But a complete turning process and nature of force can not be accurately described by means of these models.

动态切削力是切削加工过程中的基本参数，其动态变化直接影响加工过程中刀具与工件的相对位移、刀具磨损和表面加工质量等，因此动态切削力的预测仿真建模是切削过程物理仿真研究的基础，但是目前大多使用经验公式描述动态切削力，这些经验公式多少存在一些不足，难以完全真实地反映在整个切削过程中力的变化历程和变化特点。

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.
