cutting tool wear meaning in Chinese

刀具磨损

Compared with convention al speed machining , the affect and impact of thermal - dynamical coupling field play an important role in the cutting tool wear in high speed milling of aluminum alloy
与常速铣削磨损机理的不同之处在于高速旋转形成的热、力耦合的应力场对硬质合金刀具的作用与冲击影响占主导地位。
The fourth chapter introduces the theory of fractional brown movement ( fbm ) . the image texture of turning workpiece is analyzed using fbm model . after abstracting the texture character , the cutting tool wear status can be determined according to fractal dimension and average slope of the fitting curve of the logarithm power spectrum
第四章采用分数布朗运动( fbm )的基本理论，对切削工件表面纹理的图像进行分析，提取纹理特征参数，根据分形维数和图像上对数功率谱的拟合曲线的平均斜率来判断刀具的磨损状态。
