刀具

Now when your CoCreate Sheet Metal library changes, you can use the new Analyze and Redesign command to instantly update tooling and material thickness across product designs in response to changes in machinery, suppliers and material availability.

现在当您的 CoCreate 钣金资料库更新后，您可以使用新的分析及调整设计功能立即更新刀具及钣材厚度等相关资料，让您的新设计可立即回馈到您的实际加工设备、配合厂商及材料资源等。

In order to improve the teeth bending strength,the research detailedly introduced several typical dedendum transition curve in machine process and compared to several transition curve through example based on founded tool top circular radius equation.

本文详细介绍了机械加工中常见的几种齿根过渡曲线，为了提高齿根弯曲强度根据建立的各种刀具刀顶圆角半径方程通过实例进行了几种过渡曲线的比较。

This knockdown knife which has been processed through 306 times demandingly, advancedly and specially, has 17 parts and over 32 functions; its weight is just 216 kilos and it has been appointed to be the necessary equipment taken with the astronauts doing space missions by NASA.

这款由17种零件组成，具有多达32项功能的组合式刀具，经过306道严格先进的特定工序加工制成；刀组仅重216克，被美国国家航空航天局指定为航天员升空执行任务时的随身配具。

Ifs use finger shape milling cutter or a dish of shape piece of milling cutter adopt single tooth dispart law cutting time, cans process straight teeth, skewed tooth, a garden of stud gear and bring groove double helical gear or worm gear, this moment was processed gear's dentiform then by cutting tool become shape.

若用指形铣刀或盘形片铣刀采用单齿分度法切削时，可加工直齿、斜齿、园柱齿轮及带槽人字齿轮或蜗轮，此时被加工齿轮的齿形则由刀具成形。

The case-based reasoning system mainly use object-oriented method, case expression is based on the exploitation a property of the case , use value vicinity to calculate the similarity coefficients, exert two learning way to modify the case, dividedly save the case parameter and the case model.

本系统的基于实例推理模块主要采用面向对象的方法根据实例的属性特征对实例进行表示，采用权值邻近法计算相似度进行刀具实例检索，运用两级学习方式进行实例修改学习，并且把实例参数与实例模型分开保存。

In this paper, a new method for aspheric conicoid machining is offered by using normal equidistance line offsetting methods.1、Obtain ecumenic equation of normal equidistance offsetting line methods for aspheric conicoid machining induced from mathematical equations of paraboloid, hyperboloid and ellipsoid surface; reason the conditions for avoiding of tool intervening.2、Bring forward the general design project for machining tool together with some primary components based on the conception of non-sphere conicoid machining by using normal equidistance line offsetting.

其主要内容有： 1、进行了二次旋转曲面法线等距离线加工方法的理论研究，分别建立了抛物面、椭球面和双曲面的法线等距离线模型，得出了避免加工过程中刀具干涉的必要条件。 2、根据法线等距离线加工法的理论，确定了二次旋转曲面加工机床的总体设计方案，并进行了零部件的选择。

The traditional method of designing whirling tool s is complicated in calculation and low in efficience.

传统旋风铣削刀具设计方法计算繁杂、重复多、效率低，运用软件检测分析时前期工作量大。

The metal in front of the tool rake face gets immediately compressed, first elastically and then plastically.

在刀具前倾面前的金属直接受到压缩，首先弹性变形然后塑性变形。

The metal in front of the tool rake face gets immediately compressed, first elastically and then plastically.

刀具前刀面前的金属立刻被压缩，开始是弹性的，然后是塑性的。

There are also several companies in Russia for which tungsten business is not an essential activity. Here is a list of them:"Chelyabinsky electrometallurgical plant" at Ural (Ferro-tungsten and special steels),"Electric steel" in Moscow region (tungsten powder and cemented carbides), JSC "Polema" in Tula (tungsten powder, covering and bars) and JSC "Sandvik-MKTC" in Moscow (hard metal plates and cutting tools).

俄罗斯也有一些公司并不以钨初级产品为主营业务，如位于乌拉尔地区的切利尔宾斯基电冶厂（Chelyabinsky electrometallurgical plant），以钨铁和特种钢为主要产品；位于莫斯科地区的电炉炼钢公司以钨粉和硬质合金为主要产品；位于图拉地区的波勒玛公司，以钨粉、钨涂层及钨条为主要产品；位于莫斯科的山特维克-麦克提克公司（Sandvik-MKTC）以硬质合金板材和切割刀具为主要产品。

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。
