These include standard method for array modifications, experiment designs to include noise factors in the outer array, signal-to-noise ratios for analysis of results, loss function to quantify design improvements in terms of dollars, treatment of systems with dynamic characteristics, etc. [23]. Although the Taguchi method was developed as a powerful statistical method for shop floor quality improvement, a way too many researchers have been using this method as a research and even optimization method in manufacturing, and thus in metal cutting studies (for example, [27–31]).

P. Markopoulos et al. modelled system. More accurate estimation of the model parameters is achieved only if the corresponding experiment was conducted using a suitable DOE method. For most RSM studies, a special case of factorial design, the central composite design (CCD) method, is employed; however, Taguchi orthogonal arrays can also be applied. In Sect. 11 an actual example of the application of RSM method to a machining problem is presented as a case study in order to further clarify the procedure.
