刀具

L Mills 、lathe tools and the center drill tool respectively have life management.

l 铣刀、车刀、中心钻分别有刀具使用寿命管理。

The database of judging chip break is founded, which is based on the characteristic of chip breaking curve.

通过切削试验，获得了刀具主偏角、切削速度和工作材料牌号对切屑的极限进给量和极限背吃刀量的影响规律及其经验公式，并根据切屑折断曲线建立了判断切屑是否折断知识库和切屑折断预报系统。

Predicting the up-curl chip breaking of three-dimensional groove inserts;2. The database of judging chip break is founded, which is based on the characteristic of chip breaking curve.

Anhui home kitchen mainly engaged in hardware, the major tool brands are eighteen sub-Yangjiang, including slicing knife, chopping knife, chop bone knives, planer knives, fruit knives, etc.; pot pot is mainly Vernon Moore, when Kang,úZhi-Ming brands, such as electrical; operation has a single function, multi-functional soya-bean milk machine, juicer, fashionable, convenient and quick; scissors major brands are eighteen Zhang Koizumi and son, No.

安徽家好贸易有限公司主要经营厨卫五金，刀具主要品牌是阳江十八子，其中包括切片刀，斩刀，砍骨刀，刨刀，水果刀等；锅壶主要是伟龙，时康，舜龙等知明品牌的电器；经营的有单功能、多功能的豆浆机，榨汁机，款式新颖，方便快捷；剪刀类主要品牌是张小泉和十八子，大中小号，型号齐全；外加各种五金小挂件。

Clearance angle This is the angle between the machined surface and the underside of the tool called the flank face.

后角 这是已加工表面和刀具下面叫做后刀面之间的夹角。

The clearance angle is provided such that the tool will not rub the machined surface thus spoiling the surface and increasing the cutting forces.

后角 的作用是不使刀具与已加工表面摩擦，以免损坏表面和增加切削力。

The clearance angle is provided such that the tool will not rub the machined surface thus spoiling the surface and increasing the cutting forces.

后角使刀具不产生会损坏机加工面的摩擦和增加切削力。

Therefore, Fine copper fibers with stability quality were obtained under setting back engagement for 0.04-0.06mm, cutting speed for 30-60m/min and feed for 0.72-1.44mm/str, and using the tool with rake angle and clearance angle were 30° and 8°, respectively.

在背吃刀量为0.04-0.06mm，切削速度为30-60m/min，进给量为0.72-1.44mm/str的条件下选择前角为30°，后角为8°的多齿刀具，可以获得质量稳定的微细铜纤维。

This paper introduces structure,working principle,force analyzing and advantage of the clamp using in cutting bearing hole of coal car whee3. A system of the ultrasonic elliptical vibration cutting with the single longitudinal animation was developed.

利用这种结构研制了一套单激励超声椭圆振动车削系统，采用PCD刀具对LY12实心件和薄壁筒工件进行了精密切削实验，实验结果表明椭圆振动切削可以大幅度降低切削力，明显改善薄壁工件的形状精度，同时工件还具有较好的表面粗糙度。

The Company processing equipment, the special shape, special requirements of parts (such as ball valves, valve, spherical cone pieces) are using special equipment, special tools, special tooling that the valve used all parts of imports of high-precision Controlled lathes, high-precision instrument lathe processing and improve the quality of the product and technical levels.

本公司加工设备齐全，对特殊形状、特殊要求的零件（如阀球、阀瓣、球面锥面件等）均用专用设备、专用刀具、专用工装保证，阀门零件全部采用进口高精度数控车床、高精仪表车床加工，提高了产品的质量水平和技术水平。

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。
