Abstract

The dependence of the average diameter of the drops of an emulsion and their number in a unit volume on the conditions of emulsion-fog generation has been investigated. An individual drop is heated, when it comes into contact with a heated surface, to the boiling and evaporation temperatures. Under certain conditions, the total time of heating and evaporation of all drops making contact with a surface for 1 sec can be smaller than this time. In this case, active substances entering into the composition of the emulsion form a solid lubrication film on the surfaces of a piece, a chip, and a cutting tool. More than 50% of the total heat released can be removed due to the boiling and evaporation of emulsion drops from the cutting zone.
