Friction: tests in various cold forging conditions
There is one drawback to certain laws used in the Forge ® software. In this software, friction is defined once for all laws although it actually changes during the stamping operation. In order to develop a new variable friction model, Cetim has conducted a test campaign to determine the influence of four parameters on friction: speed, pressure, temperature and surface increase. However, the instability of the tests and the dispersion of the results (in particular as the test fixture and the contact geometry were not suited to this problem) did not make it possible to establish the influence of these parameters. A detailed analysis should be carried out before another test campaign is undertaken.
