Design Of Experiments
A Taguchi L27 orthogonal array was adopted to systematically evaluate the influence of three key machining parameters: cutting speed, tool-tip radius, and depth of cut. Each factor was tested at three levels, as shown in Table 2.
Table 2. Factors and their levels
The combinations generated from the design of experiments (DOE) were used as input conditions for simulation runs.
