The ratio between the force of friction and the contact force between the two moving objects is represented by a coefficient of friction µ whose value will depend on the tribology system itself and the forming process such as temperature of the sheet ram velocity contact pressure and the strains in the sheet.
Coefficient of friction sheet metal.
For glass on glass 0 4.
For rubber on tarmac close to 1 0.
The friction force is the force exerted by a surface when an object moves across it or makes an.
The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes.
This research introduces an innovative technique to find the coefficient of friction on a lubricated aluminum sheet metal surface by simulating the industrial manufacturing stamping process while using 3d digital image correlation 3d dic to track the deformation.
The coefficient of friction is the ratio of a force to a force and hence has no units.
