ANALYTICAL DETERMINATION OF CUTTING TEMPERATURE IN GRINDING AND CONDITIONS OF HER DOWN

Abstract

The paper presents a simplified calculation according to the definition of cutting temperature during grinding, with which you can set the final values of the depth of penetration of heat into the surface layer of the workpiece. This allows a new approach of determining the optimal grinding conditions, because, in the known dependences, the character of spread of temperature in the depth of a surface of detail’s layer obeys an exponential law, which excludes the possibility of establishing a final (true) values of the depth of heat penetration into the surface layer of the workpiece and limit the uniqueness of the choice of optimum modes of grinding and range of characteristics.
