The paper presents the results of research on the effect produced by various cooling methods on the chip shape, chip thickness ratio, shear angle, shearing force and machined surface roughness parameters. Dry cutting, cooling by compressed air and the Minimum-Quantity-Cooling- Lubrication (MQCL) method when finish turning of low carbon steels with different speeds of cutting and feed rates were compared. The investigations were performed in accordance with the Parameter Space Investigation method. The MQCL method is more effective for machining low carbon steel and ensures a usable chip shape. The advantage of the MQCL is confirmed by lower values of the chip thickening ratio, shearing force, machined surface roughness parameters and higher values of the shear angle. Depending on the cutting conditions, the efficiency of the MQCL method is 10 to 30% higher compared to dry machining.

W artykule przedstawiono wyniki badań wpływu różnych metod chłodzenia na kształt wióra, współczynnik zgrubienia wióra, kąt i siłę poślizgu oraz parametry chropowatości obrobionej po-wierzchni. Badano metody obróbki na sucho, chłodzenia sprężonym powietrzem oraz metodę minimalnej ilości środków chłodząco-smarujących (MQCL) przy toczeniu wykończeniowym stali niskowęglowych z różnymi prędkościami skrawania i posuwami. Badania wykonano metodą planowania badania, zwaną Parameter Space Investigation. Metoda MQCL jest najbardziej efektywna przy obróbce stali niskowęglowych i zapewnia najlepsze kształty wióra. Metoda MQCL cechuje się małymi wartościami współczynnika zgrubienia wióra, siły poślizgu oraz parametrów chropowatości obrobionej powierzchni, a także dużymi wartościami kąta poślizgu. W zależności od warunków skrawania efektywność metody MQCL jest od 10 do 30 % wyższa niż obróbki na sucho.
