coefficient of friction

n. pl. coefficients of friction
The ratio of the force of friction between an object and a surface to the frictional force resisting the motion of the object.

coefficient of friction

n
(General Engineering) mechanical engineering the force required to move two sliding surfaces over each other, divided by the force holding them together. It is reduced once the motion has started
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.coefficient of friction - the ratio of the weight of an object being moved along a surface and the force that maintains contact between the object and the surface
coefficient - a constant number that serves as a measure of some property or characteristic

For centuries, physicists have thought that the amount of force needed to push an object in order to make it slide across a surface is determined by a number called the coefficient of friction, which is the ratio between the forces pushing sideways and pushing down (basically, how much the object weighs).
The coolant stream, when aimed at a close range of an insert, lubricates the cutting edge, thus reducing the coefficient of friction and preventing the chips from adhering to the insert.
