Abstract
A comprehensive analysis of the statistical design of experiments and its application in metal-cutting studies is carried out. This subject is treated in two parts. The main concern of Part 1 is the design methodology. The applied aspects of the design such as the basic requirements to the criterion of effectiveness, factors selection, and mathematical model formulation were considered. Special attention is paid to the pre-process decisions. A 2(3) factorial experiment, complete block was chosen as the basic type of the design of experiments in metal cutting. The basic properties of this type of design were considered. It is shown that the design of experiments requires that special attention be give to the accuracy of the experimentations.
