The objective of sub-task 3.2 is to determine the friction values for different work piece materials, tool materials and lubricants as a function of the main process parameters under conditions reflecting those which are present in typical warm/hot forming operations i.e. surface expansion, work piece and tool temperature. Based on this experimental work establish mathematical formulations of friction as a function of the basic parameters.
