turning, optimization, cutting temperature, coated tools, cutting fluid, productivityAbstract
An optimization method for selecting turning parameters based on the maximum productivity criterion has been developed for machining with coated carbide cutting tools and technological cutting fluids. A mathematical model of the turning process was formulated, incorporating constraints related to the permissible cutting temperature. Using linear programming techniques, analytical relationships describing the optimal cutting conditions as functions of the principal turning parameters were obtained. A productivity growth factor was introduced to account for the increased service life of coated carbide tools as well as the cooling and lubricating performance of the technological cutting fluid. On the basis of this factor, the potential for productivity improvement under various turning conditions with the application of coated tools and cutting fluids was evaluated.
