Surface finish of machined workpiece is one of the factors to evaluate the performance of machining operations. There are different factors such as machining parameters that affect the surface finish of machined workpiece. Tool wear is an unwanted machining issue that highly affects the surface finish of machined workpiece. In a similar way, different parameters (e.g. cutting speed, feed rate and depth of cut) also affect tool wear. In this research, we investigated how the complex structure of machined workpiece is related to the complex structure of tool wear. For this purpose, we benefited from the fractal analysis. The experiments were conducted based on the variations of machining parameters (depth of cut, feed rate and spindle speed), and accordingly the fractal dimension of machined surface was analyzed versus the fractal dimension of tool wear. Based on the obtained results, the complexity of machined surface is related to the complexity of tool wear. Fractal analysis could be applied to other machining operations to analyze the complex structures of machined surface and tool and potentially make a relationship between them.

铣削加工中加工表面复杂结构与刀具磨损关系的解码

加工工件的表面光洁度是评价加工操作性能的因素之一。影响加工工件表面光洁度的因素有很多，例如加工参数。刀具磨损是一个不需要的加工问题，它会极大地影响加工工件的表面光洁度。同样，不同的参数（例如切削速度、进给速度和切削深度）也会影响刀具磨损。在这项研究中，我们研究了加工工件的复杂结构与刀具磨损的复杂结构之间的关系。为此，我们受益于分形分析。实验是根据加工参数（切削深度、进给速度和主轴转速）的变化进行的，并据此分析了加工表面的分形维数与刀具磨损的分形维数。根据所得结果，加工表面的复杂性与刀具磨损的复杂性有关。分形分析可以应用于其他加工操作，以分析加工表面和工具的复杂结构，并可能在它们之间建立关系。
