Description
The present paper gives a description of a new technological test for measuring friction coefficient using a closed die forging process. The test specimen is a cylinder of pre-defined dimensions. The result is a forging whose shape reflects the magnitude of the friction coefficient. The magnitude of the friction coefficient varies with the forging temperature and the lubricant used. The test is thus suitable for obtaining direct comparison between lubricants. The friction coefficient computation is controlled by optimization tool ISIGHT. The optimization process compares results adjusted friction coefficient FEM model and final forging.
