An Approach to Identify the Interactions Between the Control Factors in a Mahalanobis -Taguchi System

“…Table 7. Maximum differences between MTDeq(8) and MTDeq (9) in Fig. 3 MTDeq (8) and MTDeq (9) Control factors C1 C2 C3 C4 C5…”

“…Equation ( 9) is affected by the average value of the final properties PC1•C2•C3•C4•C5 (in this case, the average value of MTDeq( 9)) in the relationship between MTDeq(9) and each control factor (C1, C2, C3, C4, and C5), because the additivity of the orthogonal sequences in the optimal conditions identification program is used in the calculation process, and this effect also indirectly affects the control factors C4 and C5, which have no interaction. The differences between MTDMATH using equation (8) and MTDeq(9) using equation (9) in Fig. 2 were occurred because of this reason.…”

“…The calculation of the interaction's percentage of the 6 th and 7 th terms on the right side of the MTDMATH when the data No.1, No.2 and No.3 are substituted into equation ( 8), shows that the interaction of C1 and C2 is significant while the influence of C3's interaction is small. As in section 3.2, an experiment design using Data II (Table 6) and the optimal conditions identification program are used to obtain equation (9).…”

“…The similarity of MTDeq (9) and MTDeq (9) in Fig. 3, makes it possible to obtain an algebraic expression with MTDeq (9) as a dependent variable and the control factors C1, C2, C3, C4, and C5 as independent variables.…”

“…The Taguchi methods were first developed by incorporating the concept of error factors into the design of experiment [2][3][4][5][6][7][8][9], and currently consists of three components: static, dynamic, and MTS. In addition, the MTS consists of MT, MTA, RT, and T. These are now widely used especially in the industrial and medical fields [10][11][12][13].…”
