Coefficient Of Friction Sheet Metal

Typical values for the coefficient of friction when sliding is occurring i e.

Coefficient of friction sheet metal.

For polished oiled metal surfaces less than 0 1. The friction force is the force exerted by a surface when an object moves across it or makes an. Static friction is friction between two or more solid objects that are not moving relative to. 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.

The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes. For rubber on tarmac close to 1 0. By considering the influence of the bending boundary friction model was coming into existence to predict area of contact at punch face and coefficient of friction. To determine frictional coefficient for stretching forming 14 in sheet metal a friction test is developed.

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.
