The strip drawing test of sheet metal was used in the simulation of the steel sheet steel tool friction contact conditions during a drawing operation.
Factors influencing friction in steel sheet forming.
Various lubricants are used to reduce the friction during the metal forming.
As the factors produce a dispersion effect on friction the following variables were chosen.
Johan hol development manager from triboform engineering describes frictional influences that are unique to ahss forming and how the accuracy of predicting ahss automotive parts forming may be increased by using an alternative friction model.
Die and blankholder surfaces for deep drawing sheet metal must be as smooth as possible they should be ground and lapped to mitigate friction.
There is a need to study the various factors affecting the friction.
In sheet metal forming friction has a major role in knowing the properties of metals.
The results further showed that the surface topography and sample orientation in the rolling direction of the sheet are significant factors that influence the friction coefficient.
The friction conditions are dependent on the tribology system i e.

If friction exists more than necessary it has a negative impact on characteristics of a product.
The coefficient of friction in stribeck curve depends on sliding velocity and contact pressure.
The influence of tool steel microstructure on friction in sheet metal forming kirkhorn lanny lu.
The influence of forming speed over pressing and holding time on springback behaviour of sheets was studied numerically.
Any type of friction will increase force hence stresses in the material.
Friction and lubrication are important factors when trying to accurately simulate advanced high strength steel ahss metal forming processes.
