| 摘要: |
| 本文提出了一种运用功率累积和与 n维随机向量相关度量监测刀具磨损的新方法，即通过计算刀具三向振动加速度的相关度量系数，主轴扭矩或某项振动加速度的功率累积和综合监测刀具的磨损、破损以及刀具磨损的程度。该法在简单性、可靠性等方面比以往提出的方法有较大的进步，因而使得本方法具有很大的应用前景。文中对该法的理论基础进行了严格的证明，并给出了实验论证结果。 |

| Abstract: |
| At present. monitoring cutting tool wear becomes one of the most important problems to be solved urgently in automatic manufacturing. For this a new monitoring method is proposed using correlation of N dimensional Random Variables and cumulative power sum，namely comprehensively monitoring cutting tool wear and leakage by acquiring the correlation coefficient of vibration accelerations in three mutually perpendicular directions，and the cumulative power sum about torque of spindle or about any vibration acceleration. This method makes greater progress than the ones proposed before in the aspects of reliability and simplicity. So it has a bright future in application area. The theoretical basis of the method is strictly proved and some experimental results are given in this paper. |
