查询词典 flank movement

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。

The plan was to execute a flank movement to the left, cut off and capture the viceroy.

在营地被踏碎的雪地上到处都晃动着士兵们的身影。

It is one of the most widely used methods to groove and disconnect the workpiece with the cutter,but in the process of cutting the movement of the cross-feed can reduce the working orthogonal clearance,which increases the friction between the tool flank of the cutting tool and the machined surface,and hence results in the break of the workpiece and the working tool.

用切断刀对被加工工件切断或切槽是生产中应用最广泛的加工方法之一，但在切削过程中横向进给运动的影响使刀具工作后角减小，加剧了刀具后刀面与加工表面之间的摩擦，从而会导致工件被挤断，刀具易折断。

Secondly, it is even more difficult to understand why the historians ascribe to this manuvre the deliverance of Russia and the overthrow of the French; for, had other circumstances preceded, accompanied, or followed it, this flank movement might as well have led to the destruction of the Russian army and the .

第二，尤其令人难以理解的是，历史学家们究竟是怎样看出这次军事行动使俄国得救而使法国失败；因为这次侧翼进举，如果在此之前，或与此同时和在此之后发生另外的情况，就可能对俄国军队来说是毁灭性的，而对法国军队来说则是幸运的。

"Every contingency has been provided for; if he is concentrated at Brünn.…" And Prince Dolgorukov gave a rapid and vague account of Weierother's plan of a flank movement.

&唉，横竖一样，&多尔戈鲁科夫站立起来，打开桌上的地图，匆促地说，&各种情况都预见到了，假如他驻扎在布吕恩附近……&多尔戈鲁科夫公爵急促而不清晰地叙述了魏罗特尔的侧翼迂回运动计划。

As to the opening blow which crushed the front of 2nd Division prior to the turning movement against its right flank, there are no discrepant data.

关于中共军队迂回第2步兵师右翼之前粉碎该师正面的首次突击，不存在相抵触的资料。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
