| Abstract | The surface finishing of turned parts determines the functionality of the product and the turning requirements for making the parts. Conventional roughness parameters used for measurement of surface finish are not able to characterize technical surfaces clearly. The widely used and universally recognized parameter of surface is roughness average height Ra (Chiffre, 1999). However, it cannot give adequate information regarding the complexity and irregularity of surface. The application of fractals geometry in surface related phenomena has been developed very recently and it shows great potential in the field of surface finish measurement. The fractal dimension is a measure of how densely the fractal occupies the space in which it lies. Number of researchers have proposed in different ways that fractal dimension can be used as machining performance parameters. This research has used linguistic variables instead of numerical values to avoid vague information about the degree of performance between two alternatives and cannot estimate its performances with exact numerical values. Linguistic variables are universal approximation and context dependent. The interaction between cutting conditions and performance measuring parameters are investigated by using ID3 algorithm through constructing decision trees. Decision trees of turned surfaces demonstrated the feasibility of fractal dimension as a machining performance parameter and have impact in process planning. |
