提出了基于分形理论的刀具磨损研究新方法，从理论、实验、计算３个方面讨论了刀具主后刀面磨损的分形特征与分形结构，以分形维数作为特征量，在物理意义层次上初步揭示了切削速度与刀具磨损分形结构之间的映射关系。
A new method of tool wear study based on fractal theory was put forward. The fractal features and fractal structure of the main flank wear were discussed theoretically, experimentally and computationally. Taking the fractal dimension as the feature quantity, The relationship between cutting speed and tool wear fractal structure is revealed.
