THE ESTIMATION OF POSSIBILITIES OF THE TURNING PRODUCTIVITY RISE WITH THE USE OF COATED CARBIDE CUTTING TOOLS AND TECHNOLOGICAL CUTTING FLUID

Abstract

The method of optimization of the cutting regime at turning with the use of coated carbide cutting tools and technological cutting fluid on the criterion of maximum productivity is developed. Mathematical model of cutting process at turning taking into account limitations on the cutting temperature is developed. With the use of method of the linear programming analytical dependences of the optimum cut-ting regime on the turning parameters are defined. The factor of turning productivity rise, which takes into account the increase of coated carbide cutting tool life, cooling and oiling properties of technological cutting fluid is a creation. Based on that factor the estimation of possibilities of the turning productivity rise of the coated carbide cutting tools and technological cutting fluid application for various turning pa-rameters is executed.
