TECHNOLOGIES AND EQUIPMENT FOR MACHINING, PHYSICOTECHNICAL PROCESSING, NON-CUTTING SHAPING

Melnikova M. A., Grigoryants A. G. � Transformation features in polyethylene film at laser labeling

Necessity for labelling materials nowadays is caused by continuing development of technologies. So far as virtually all industrial production has its own packaging when offered for sale, then it is most reasonable to put a protective image directly on the most widespread packaging material, which is polyethylene. An important stage is elicitation of a possibility of marking the material and identification of laser treatment features.
Key words: laser, labelling, films, polymer, polyethylene film, influence, laser emission

Kiryushin I. Ye. � Wear resistance of surface coating after a high-speed turning operation of the hardened powder steel

It is established that surface condition became worse when turning hardened steel S49 of 42�45 HRC at cutting speed enhancing from 60 to 300 m/min. Quality of the surface layer improved after achieving the cutting speed as of 300 m/min, which corresponds the beginning of high-speed processing. When the cutting rate goes up to 400 m/min the surface condition becomes worse significantly.
Key words: wear resistance, surface coating, steel, SFPM rate
