摘要：
This paper investigates the influence of viscosity of oil on flank wear, crater wear and finished surface roughness with minimal quantity lubrication (MQL) system, when changing the kinds of coating films of the hob. Experiments were carried out using a fly tool. As a consequence, the following points were clarified: (1) When using the TiN and (Al, Ti) N coated tools, the flank wear and the crater wear increase with an increase of the viscosity of the oil in the range from 19.1 mm2s to 30.5mm2/s in the viscosity grade, after that, it decreases with the oil having high viscosity of 47.6 mm 2/s. (2) The surface roughness obtained with the low viscosity of the oil is the smallest in all oils tested at the beginning on cutting, and it showed almost the same value as the theoretical roughness at the end of cutting. (3) From the viewpoints of the primary performance such as the flank wear and the crater wear, and the secondary performance of the oxidation stability, the oil having low viscosity of 19.1 mm2/s is suitable for MQL system in hobbing.
