| Summary: | The analysis of the phenomena occurring during the interaction of polymeric materials with aggressive media is carried out. Scientifically substantiated is the chemical effect on workpieces made from polymeric materials before cutting. In this case, it is advisable to carry out the processing of polymers with an aggressive medium in such a way as to ensure cracking or loosening of the surface layer to a certain depth, without changing the chemical properties of a particular polymer. The results of experimental studies of samples in tension after appropriate chemical treatment are carried out. The research results analysis made it possible to establish the fact that the treatment of the studied polymeric materials with active media leads to a significant decrease in strength. Methods have been developed, the essence of which is a directed change in the properties of the processed material, by preliminary chemical treatment of the surface layer, in order to reduce the resistance to destruction of the surface layer of the workpiece during its subsequent interaction with the cutting tool.
