The results of experimental investigations of surface quality after the lathe machining of polymeric materials subjected to preliminary treatment with surface-active substances are presented. The new combined method for polymer parts was developed. This method is based on directed change in the polymer properties by preliminary chemical treatment of the surface layer so as to reduce its resistance in the cutting zone. It has been demonstrated in experiments that the preliminary treatment of workpiece with surfactants ensures an improvement in quality of the surface machined by turning. This is indicated by a reduction in the roughness parameters by a factor of 2–4.5, and the minimum roughness is achieved at a cut depth equal to 1.0–1.15 the surfactant penetration depth into the material
