This chapter deals with fractal dimension modelling in machining operations. The study considers the fractal dimension to describe surface roughness. Four different machining operations, including CNC end milling, CNC turning, cylindrical grinding and EDM are carried out on mild steel (AISI 1040) work-pieces. The surface roughness data are used to develop models for predicting fractal dimension using artificial neural network (ANN). From the results of all machining operations, it is seen that developed models can predict fractal dimension very accurately.
