WebFriction and Friction Testing. Friction is a restraining force that limits metal flow resulting from contact with another surface during sheet forming. Friction is influenced by the complex interaction between the sheet steel, lubricant, and tooling material, as well as many parameters of the forming system, some of which are shown in Figure 1. http://www.dviaviation.com/wear-friction-testing.html

WebWhat is Friction? Friction is part of the science of physics. This explanation from the Khan Academy is terrific so I will borrow it: “The force of static friction is a force between two surfaces that prevents those surfaces from sliding or slipping across each other.This is the same force that allows you to accelerate forward when you run.
