Purpose.To develop the algorithm of determination of the cutting mode at grinding of working surface of mandrel cold-rolling of pipes on the stage of removal of draft allowance.
Methodology. The algorithm of determination of three constituents of the cutting mode at grinding of draft allowance is presented . It is suggested to count a longitudinal feed on a turn from the necessary roughness of the processed surface, and combination of transversal feed on a passage-way and rotation feed of workpiece - on the mathematical model of process and entered coefficient of possible resilient deformation of the technological processing system. A mathematical model takes into account loop of cutting process in the resilient system and nonlinear dependences of cutting force from material removal rate. The application programs of decision of task of determination of such combination are created three constituents of the grinding mode which provide a maximum of the productivity. A method and algorithms developed are utilized in the computer aided manufacturing system for operation of grinding of working surface of mandrel cold-rolling mills pipesReferences
