刀尖

He then took a small knife out of his pocket, speared a sausage on the end of it, and began to eat.

他从自己的口袋里掏出一把小刀，把一根香肠戳在刀尖，吃了起来。

The so-called cutter location point, the flat end mill tool axis refers to the point of intersection with the bottom tool; for ball-end milling is the ball part of the core; for tools is the tip; the drill is the drill point; for wire electrode cutting machine, it means that the axis line of the electrode surface and the focus of parts.

所谓刀位点，对于平底立铣刀是指刀具轴线与刀具底面的交点；对于球头铣刀是指球头部分的球心；对于车刀是指刀尖；对于钻头是指钻尖；对于线电极切割机床，则是指线电极轴心与零件面的焦点。

A very large 10 clearance angle reduces the strength of the tool tip, and hence normally an angle of the order of 5-6°is used.

过大的后角就减小了刀尖的强度，因此，后角通常为 5～6°。

Results show that the milling tool with rake angle 5°, clearance angle: 10°, helix angle: 45° and corner radius: 1 mm is tested on the surface integrity experiment.

实验结果表明，前角5°，后角10°，刀尖圆弧半径为1mm，铣刀螺旋角为45°的几何结构铣刀完成了表面完整性试验中。

In this paper an innovative method for machining sculptured surfaces is presented. By using a disc cutter with a concave end instead of traditional ball-ended or drum-shaped tools, and adjusting the cut- ted axis to swing relative to the component being machined under some special rules, the envelope formed by the trace of the tool-nose may have the same derivative up to the third order as the required theoretical surface.

本文提出了一种加工自由曲面的新方法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1～3阶导数，从而在保持精度不变的前提下，使实际行程次数得以大幅度的减少。

By means of using a disc cutter with a concave end instead of traditional ball-ended or flat-ended ones,and adjusting the cutter axis to move relatively to the component being machined according to some special rules,the envelop formed by the trace of the tool-nose in each pass and the required surface have the same derivatives up to the second order in the plane normal to the feeding direction.

采用二阶密切曲率法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1阶？

I'm scared for children yet to be abducted, scared for the pregnant woman raped at knife point on the New Jersey Turnpike, scared for what violence does to one's life, how it squats inside the hollow heart like a dead cricket.

我对儿童遭受诱拐深感恐惧，对孕妇在新泽西州因为刀尖的威胁而遭受强奸感到恐惧，对那些施加于生命的强暴深感恐惧，它是如何地像一只死蟋蟀蜇伏在空洞洞的心脏里。

Based on the parametric equations of blade surfaces and hub surface, and selected form specification of the ball end mill, we use MATLAB to calculate the coordinates of tool paths and tool-axis orientation.

本文系以叶轮叶片面及轮毂面的曲面参数方程式资料为基础，选定刀具形状规格后，应用MATLAB程式来计算刀具的刀尖点座标及刀轴方向。

Depending upon who did the modification, the ends were reground to either a spear or clip point.

因为是长刺刀刀身截短的原因，这种刺刀的血槽是一直延伸到刀尖的。

When the work piece or tool for reciprocating movement and feed rate on each trip through the measurement of inches.

刀具的几何形状――以刀尖平面和刀具角为特征――对于每一种切削工艺都必须是正确的。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
