The Method for Determining the Friction Coefficient in Relation to the Hot Forging Processes

A method for determining the friction coefficient was developed and experimentally tested by comparing theoretical calculations of the relative volume of radial channels filling with various convergence angles of generating line for various friction coefficients and experimental data on the value of filling these channels. Relative volume of metal extruded into the channel was selected as criterion for simulation the channel filling conditions depending on the friction coefficient. Relative error of the experiment results doesn’t exceed 6% according to the linearized models of this criterion.
