The friction that occurs in forming processes plays a fundamental role in the industry as it can be responsible for both manufacturing failure and its success. Scientific research has been done to try to understand this phenomenon as well as simulation software has been implemented aiming to predict the tribological behavior of the metallic pair in contact. Thus, this chapter is dedicated to the analysis of the main parameters that can influence the coefficient of friction, especially for metal manufacturing processes. Some simulation models that try to predict the behavior of friction under certain conditions of process speed, contact pressure and operating temperature will also be presented.

“…Friction is one of the basic phenomena that should be considered when designing the deep drawing processes (Sigvant et al, 2019). A quantitative indicator of the friction phenomena is the coefficient of friction, the value of which depends on many parameters related to the workpiece material, tool material, contact conditions, forming temperature and lubricants used (Xu et al, 2020;Zabala et al, 2022). Due to the variety of pressure values occurring in different areas of the drawpieces formed, it is necessary to use various tribological tests to assess the friction and lubrication conditions.…”

Friction is an undesirable phenomenon in the flange area of the drawpiece in sheet metal forming processes, causing a deterioration in surface finish and a decrease in the formability limits of the sheet metal. The aim of this work is numerical analysis using the finite element method of the strip drawing test with two rounded countersamples. This test simulates friction conditions in the flange area of the drawpiece. The results of the experimental research on the influence of surface roughness on the value of the friction coefficient of S235 steel samples were used to verify the numerical results. The relation between the real contact area and the mean roughness Ra of the countersamples was determined. The real contact area increases with the increase of the mean roughness Ra. In sheet metal forming processes, the coefficient of friction depends on the real contact area, and its value increases with the increase of the real contact area.

“…Another enhanced version of coulomb law incorporates the pressure and velocity dependent variation of friction coefficient. Alaitz Zabala [8] demonstrated the complexities of a tribological system and its effect on forming simulations and therefore, it is necessary to incorporate the effect of process variables on the friction coefficient. Using some advanced friction models [9], the real time friction coefficient value can be predicted in the simulation instead of assuming a constant friction coefficient value for all the elements of a blank.…”

In a deep drawing process, friction at the sheet metal-die contact interface affects the material flow in the flange as well as at the die entry affecting product quality significantly. The accuracy of predicted drawing force and thinning in deep drawing simulation strongly depends on friction modelling. The Coulomb friction model with a constant coefficient of friction is generally assumed in simulations. In reality, the actual friction coefficient depends on process variables such as local contact pressure, relative sliding velocity, and strain in the sheet material. In this work, an approach is presented for deep drawing simulation of dual phase (DP600) steel sheets incorporating the effect of these variables on the friction coefficient. Strip drawing tests under conditions similar to that exist in the flange area during deep drawing have been carried out. Deep drawing simulations have been performed using two friction models taking into consideration the variation of friction coefficient with respect to pressure and velocity. The predicted punch force and thickness variation are validated using deep drawing experiments. A considerable improvement in the accuracy of predicted results has been observed when compared to a constant coefficient of friction.
