In article one of ways of measurement of frictional forces on a forward side of the cutting tool taking into account contact length presents in a cutting zone which is realized on the special equipment in the form of the stand made on the basis of the lathe screw cutter of model 1A616 and the developed original technique of measurement of frictional forces and lengths of contacts when cutting materials. So the equipment allowed to make high-precision measurements of frictional forces on a forward side of a cutter for the purpose of studying of tangents forces the way of measurement of these forces which is given in article was developed, justified and tested. It is established that by means of this way the device described in article, measures tangents force on a forward side of the cutting tool. As a result of measurements by means of the developed way and the device on techniques of measurement of frictional forces and lengths of contacts between a cut-off layer and a forward side of the tool friction forces for pair “40XH2MA-T5K10” are experimentally determined.
