切削刃

It was shown that excessive cutting speeds cause a rapid failure of cutting edge; thus, the tool can be declared to have a short life.

过高的切削速度会使切削刃快速失效；这样，就意味着刀具的寿命不长。

The results showed that: the knifepoint radius, the cutting edge blunt round radius and feed rate are considered as critical parameters to get high-quality for the machined surface.

结果表明：正确地选择刀尖圆弧半径、切削刃钝圆半径和进给量是获得高质量加工表面的有力保证。

However, logarithmic spiral can be used to substitute for the Archimedes curve to solve such problems and guarantee the stability of cutter machinability .

传统的阿基米德螺线齿背的铲齿成形铣刀在重磨前刀面后，切削刃上各点的后角将发生变化，从而影响刀具切削性能的稳定。

Depth of penetration of a cutting tool -- to inches dollars -- is the tool to the work piece distance.

切削速度是切削刃通过工件表面的速率，它是以每分钟英寸来表示。

Cutting speed is the cutting edge of work piece surface rate, it is inches per minute to show.

切削速度是切削刃通过工件表面的速率，它是以每分钟英寸来表示。

It is sharp, wear-resistant, the PDC can be self-sharpening cutting teeth as a cutting edge in low WOB high penetration rate can be,(cone bit higher than 2 times more) and high-footage (cone bit higher than the 4-6 times), applicable to soft - in the hard formation.

它以锋利、耐磨、能自锐的PDC切削齿作为切削刃、在低钻压能获得高钻速、（高于牙轮钻头2倍以上）及高进尺（高于牙轮钻头4-6倍），适用于软-中硬地层。

For the relieving shaped milling cutter with the traditional Archimedes back curve, the relief angle of each point on the cutting edge is changed after refacing the cutter.

传统的阿基米德螺线齿背的铲齿成形铣刀在重磨前刀面后，切削刃上各点的后角将发生变化，从而影响刀具切削性能的稳定。

Through improving the geometric parameters of the cemented carbide bit such as the rake angle of main cutting edge,outer fringe cusp and chis...

通过对钻削加工用硬质合金钻头的几何参数进行改进，主要是对主切削刃前角、外缘转点以及横刃进行改进，达到降低钻削功率的目的，同时，利用多元线性回归理论，得出基于实验数据的多元回归钻削功率的数学模型，从理论上证明此次刀具改进的有效性。

Some techniques which are used for the measurement of grinding temperatures,such as infrared radiation pyrometers,optical fiber infrared radiation pyrometer, two-color infrared system and infrared imaging system,are summarized,compared and discussed.

磨削过程中，大量无规则离散分布在砂轮表面的磨粒对工件划擦、耕犁和切削综合作用，其所产生的热体现为工件的温升、砂轮与工件接触面的温升、工件已磨削表层的温升、磨粒切削刃温度和切屑温度。

By making reasonable assumptions about the mechanical boundary conditions of orthogonal cutting,a slip line field model is constructed by a trial and error method,in which the influence of cutting edge roundness is considered.

对正交切削过程的力学边界提出了合理假设，用试探法建立了考虑切削刃钝圆影响的滑移线场模型及相应的速度场模型。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
