THE INFLUENCE OF THE FUNCTIONAL GEOMETRY OF THE CUTTING TOOLON THE MAINCUTTINGFORCE IN THE STRING OPERATION

Abstract

he quality of the machined parts is strongly influenced by the rigidity of the technological system, but also by the size and variation of the forces that occur during the cutting process. At a certain stiffness of the work piece, the macrogeometric deviations of the shape depend on the size and direction of actuation of the cutting forces that occur in the cutting process. The paper presents the variation of the cutting force values for the turning operation due to the working geometry of the cutting tool during the cutting process in order to optimize the geometry of the active part of the cutting tool. Thus,there was analyzed the influence of the angle values of the main cutting direction on the values of the cutting forces.
