Numerical Simulation of Lubricated Wire Rolling and Drawing

Friction and lubrication are important factors in metal forming processes. Unoptimised frictional parameters can cause lower productivity of manufacturing machinery and deteriorate surface quality of the final product. Optimised frictional parameters are, in most cases, achieved by controlled lubrication of contact between product and forming machine. Lubricant and contact surfaces experience high pressures with temperature and velocity variations. Due to these effects both material and lubricant properties are changing, which can have significant influence on the shape and quality of the final product. Numerical modelling of metal forming processes reduces time and cost of the physical experiments required when a new type of metal product is introduced into production. This thesis deals with numerical modelling of lubricated contact between two surfaces during wire rolling and drawing processes using Finite Volume Method and OpenFOAM software.
