RT Journal Article SR Electronic A1 Vasilko, Karol T1 Tribological Mechanism in Machining and Its Use JF Manufacturing Technology Journal YR 2018 VO 18 IS 4 SP 692 OP 696 DO 10.21062/ujep/162.2018/a/1213-2489/MT/18/4/692 UL https://journalmt.com/artkey/mft-201804-0030.php AB It is a well-known fact that during cutting there occurs an extremely high degree of chip plastic deformation [1,4,5,11] These deformation structures require attention as they influence technical and economical results of cutting (cutting forces, quality of machined surface, tool wear, cutting temperature) [8,9,15,21]. The paper analyses the options of influencing the deformation field in chip with the aim to improve cutting proces.
