Example text

Practice of the Taguchi method fosters a team approach to design optimization because participation of people from engineering, manufacturing, testing, and other activities may be necessary for complete variable identification. EXPERIMENTAL EFFICIENCY In most cases, the Taguchi experiment design using an orthogonal array requires the least number of test runs. A full factorial experiment with 15 factors at two levels each is performed with a test matrix with 32,768 (215) test runs. A fractional factorial experiment with an orthogonal array suitable for 15 two-level factors consists of only 16 test runs.

Each factor can be applied at two levels (Table 5-3). The experimenter wants to determine the optimum combination of the levels of these factors as well as the contribution of each to product quality. Experiment Design There are three factors, each at two levels, thus an L4 will be suitable, per Table 5-1. An L4 OA with spaces for the factors and their levels is shown in Table 5-4. This configuration is a convenient way to lay out a design. Because an L4 has three columns, the three factors can be assigned to these columns in any order.

Color quality response curve to produce the best result and yet exhibit minimum variation around the optimum result. To see how the Taguchi technique is used for many factors, consider once again the process of determining the best recipe for a pound cake (Figure 3-4). The objective is to determine the right proportions of the five major ingredients—eggs, butter, milk, flour, and sugar, so that the recipe will produce the best cake most of the time (Figure 3-5). Based on the past experience of involved team members, the working ranges of these factors are established at the levels as shown in Figure 3-6.
