Theoretical calculation of the lubrication-layer thickness during metal drawing
The calculation of the lubricant-layer thickness using a fluid-mechanics approach is shown for the case of the cold drawing of metals. Examples of the calculation for a solid lubricant layer and a different geometry of the die entering angle are shown. The calculation of the effect of inertial force with a high drawing speed on the lubricant-layer thickness is also presented.
