Parameters of process of machining into account temperature models

In work the basic processes of machining and their influence on quality and durability of cylindrical products, calculated temperature modes are considered at cutting of pipes, parameters of process of cutting are chosen taking into account size and a sign on temperature residual stresses. By machining understand different types of cutting: turning, drilling, milling, grinding, honing, polishing. In this regard, shows how the processes of machining affect the quality of tubular products. The aim is to give a cutting detail desired shape. Also examined parameters of the cutting process, selected to the value and sign of thermal residual stresses. Residual stresses in metal cutting result from uneven plastic deformation and significant heating of the surface layers. Solving the problem of thermoelasticity can determine the stresses induced by heating. Based on the terms of the onset of plastic deformation is not on the surface of the part after passing through the tool, you can optimize the cutting parameters for the treatment of various axisymmetric metal. Thus, knowing the relationship between these parameters and the mechanical properties of the workpiece material and geometry can estimate the stress intensity as a function of the initial temperature and cutting data processing tube. Then based on the results built relationships and dependencies critical cutting parameters for tubular products of different materials and some limiting parameter ratios machining tube. The paper presents the method of determination of the limit relations parameters of the cutting process for axisymmetric products with temperature heating surface due to friction when turning. The method allows to determine the voltage at the surface of the workpiece and the rational selection of the process parameters, depending on the part geometry and the material.
