The theoretical and experimental research results of the new method for polymeric materials turning are presented. A distinctive feature of the developed method is the preliminary deformation of the material by twisting the workpiece.. It is theoretically shown that the maximum stresses value during twisting is formed on the workpiece surface layer. It has been experimentally proved that the workpiece deformation by twisting leads to changes in the stress-strain state of the polymer chain. The workpiece predeformation by twisting allows to obtain a higher quality surface layer compared to traditional turning.
