CONSTRAINED CUTTING RATE-TOOL LIFE CHARACTERISTIC CURVE, PART 2 - CONVEX-PROGRAMS

Based on the concept in Part 1, Theory and General Case, algorithms to determine the constrained R-T characteristic curve are established fo r convex constrained machining economics problems. The first algorithm is for posynomial problems with the linear-logarithmic tool life equa tion. The R-T curve may be determined by applying the simplex method t o the log-dual problems. Sensitivity analysis of the optimal simplex t ableau enables obtaining the loci of optima easily. The second algorit hm is for the quadratic poslygnomial problems with quadratic-logarithm ic tool life equation using the property of primal-dual feasibility. E nd milling examples constructed in Part 1 illustrate the algorithm com paring to the exhaustive method.
