请高手帮我翻译下摘译，汉译英，多谢 摘要：为了快速准确的测量出PCBN刀具在干式连续车削条件下刀具使用寿命及其切削性能，选用两种不同的PCBN刀具，在不同切削速度下，对淬硬钢进行车削试验。利用泰勒公式，通过对公式中的系数m和A的计算，在刀具尚未达到磨钝标准时（后刀面平均磨损0.3mm），理论预测出两种刀具使用寿命，在此基础上评价出两种刀具的切削性。最后对两种尚未达到磨钝标准的刀具继续进行切削实验，测量出了刀具的实验寿命，从而对理论预测进行了实验验证。结果表明，利用泰勒公式所理论预测的刀具使用寿命与实验所得到的刀具使用寿命虽然具有一定的误差，但是理论所计算的结果可以基本反应出刀具的切削性，并可以理论预测出低速切削时刀具的耐用度。 关键词：泰勒公式；PCBN刀具；刀具使用寿命；刀具切削性；切削速度 |

Abstract: In order to measure the useful life and cutting performance of PCBN cutting-tools under the condition of continuous dry turning, this paper selects two different types of PCBN cutting-tool to do turning experiment of hardened steel at different cutting speeds. Using the Taylor formula, this paper calculates the coefficient m and A in the formula, before the cutting-tool reach the blunt standard (that is to say, the average abrasion of the cutting-tool flank is 0.3mm), it predicts the useful life of the two types of cutting-tool theoretically, based on which estimates the cutting performance of the two types of cutting-tool. And then, this paper measure the useful lifetime through above-mentioned measure of the two types of cutting-tool which do not reach the blunt standard. Finally, the theoretical prediction is experimentally verified. The result shows that, even though there is a certain degree of error between the useful lifetime of cutting-tool predicted by Taylor formula theoretically and the one obtained by experiments, the calculated theoretically result can show the performance of cutting-tool basically, and can predict the performance degree of low-speed-cutting cutting-tools theoretically. Key words: Taylor formula, PCBN cutting-tool, useful lifetime of cutting-tool, cutting-tool performance, cutting speed |

| Abstract: In order to quickly and accurately measure the continuous PCBN cutting tools in dry turning and cutting tool life under the conditions, the choice of two different kinds of PCBN tools in different cutting speeds, the turning of hardened steel test. Using the Taylor formula, the coefficient on the formula calculation of m and A, in the blunt tool has not yet reached the standards (the average flank wear of 0.3mm), theory predicts two kinds of tool life, in this based on the evaluation of the two of the cutting tool. Finally, the two have not yet reached the standard blunt tool to continue cutting experiment, the experimental measurement of the life of the tool, and thus the theoretical prediction was experimentally verified. The results show that the theoretical predictions by using the Taylor formula for the tool life obtained with the experimental tool life, while having some errors, but the theoretical results calculated by the basic reaction of the cutting tool, and can predict the low-speed cutt |
