cutting bit

While the story might be a bit run-of-the-mill for something so ultimately cutting-edge, the dialogue itself is quite often riotously funny.(尽管有些情节由于太过尖刻而显得一般，然而对话本身还是相当有趣的。)

On the basis of that the diamonds distribute in the impregnated bit homogeneously, the article calculates the cutting depth and the normal force on the protrusion diamond on the crown.(本文以金刚石在孕镶钻头中均匀分布为基础，从理论上推导出唇面径向不同位置的金刚石切深、受力。)

It is the key to ensure that PDC bit has choiceness of the work performance to reasonably place cutting.(合理的布齿是保证PDC钻头有优良工作性能的关键。)

Rock cutting by a step ped bit has been studied with experimental stress analysis and is tested under atmospheric pressure.(本文用平面光弹方法，对阶梯金刚石钻头切削刃下岩石的应力进行分析。)

Based on analyses about the structures and existing problems of integrally retractable alternative cutting element bits, a integrally rotary replacing cutting element bit was proposed.(在分析各国整体切削具不提钻可换式钻头结构及存在主要问题的基础上，提出采用整体旋转切削具可换式钻头。)

Diamond cone bit is a new drill bit which make use of cutting cutters interacting with rock slowly and alternately.(轮式金刚石钻头是利用切削齿缓慢交替切削运动来破碎岩石的新型钻头。)

Such as easy cutting paste, a bit not careful density board they smoke.(譬如容易切割糊，稍不留神密度板就冒烟了。)

The self-feeding bit consists of the rotary nozzle, the cutting conformity device and the power supply device etc.(自进式钻头由旋转喷嘴、钻屑整合装置、推力提供装置等组成。)

Based on the data, this study studies the cutting force affected by the characteristic parameter of PDC cutters, the mechanics property parameter of rocks, the working parameter of PDC bit.(PDC齿切削载荷的分析，以实验测试的数据为基本依据，对钻头布齿结构参数、切削齿特性参数、岩石的力学性质、钻头的工作参数等因素对PDC齿切削力的影响规律做了全面、系统的研究。)

In reality, the image is a bit of an illusion: the lightning was far from the Observatory and the laser only appears to be cutting through the bolt.(在现实中，这个图像相当于一种错觉：闪电远离着天文台，激光似乎切断了这个闪电。)
