RT Journal Article SR Electronic A1 Jaromir, Stusek A1 Tomas, Macak T1 Design of Experiments for CNC Turning JF Manufacturing Technology Journal YR 2015 VO 15 IS 3 SP 448 OP 455 DO 10.21062/ujep/x.2015/a/1213-2489/MT/15/3/448 UL https://journalmt.com/artkey/mft-201503-0033.php AB This paper follows on research on published in the Journal of the Academy of Business & Economics [1] (authors Hron and Macak) and complements previous research on the area of design of experiments using a factorial design. Further results are compared between Fuzzy Logic and Design of experiment approaches.The main purpose of this paper is to compare the results between the mathematical model of optimization of CNC turning and the optimization using the fuzzy-logic method for multi-criteria optimization of cutting conditions. The comparison in this paper verifies these two approaches. In the case of an inconsistency, the objective of this paper would be to suggest a new approach where the incorporation of the mathematical model (as an approximation form) and the optimization of fuzzy-logic would be consistent.
