What precise value of coefficient of friction to be used in all the stages of rolling a wire rod ,for 3D model development? Whats the method to calculate the value of coefficient of friction for all stands?
Inclined surface test is used to measure static friction of material. In context to rolling of wire rod its a dynamic process under the influence of many variable parameters in each stages of rolling so how do to find coefficient of friction in this case? There are many empirical formulas to find the coefficient of friction. Which formula is widely used and provides the most reliable result?
