Question: An engineer has performed an experiment to study the effect
An engineer has performed an experiment to study the effect of four factors on the surface roughness of a machined part. The factors (and their levels) are A = tool angle (12, 15), B = cutting fluid viscosity (300, 400), C = feed rate (10, 15 in/min), and D = cutting fluid cooler used (no, yes). The data from this experiment (with the factors coded to the usual +1, -1 levels) are shown in Table 8E.4.
Answer to relevant QuestionsAn experiment was run to study the effect of two factors, time and temperature, on the inorganic impurity levels in paper pulp. The results of this experiment are shown in Table 8E.5: a. What type of experimental design has ...A process engineer is trying to improve the life of a cutting tool. He has run a 23 experiment using cutting speed (A), metal hardness (B), and cutting angle (C) as the factors. The data from two replicates are shown in ...Show how a experiment could be set up in two blocks of 16 runs each. Specifically, which runs would be made in each block? Twenty observations on the time to failure of a system are as follows: 1054, 320, 682, 1440, 1085, 938, 871, 471, 1053, 1103, 780, 665, 1218, 659, 393, 913, 566, 439, 533, and 813.
