An Investigation on Effects of Minimum Quantity Lubrication Technique on Surface Roughness in the Hard Milling Process
Downloads
The main objective of this paper is to study the effects of input parameters including the cooling lubrication modes, cutting speed (V), and feed rate (f) on surface roughness in hard milling. The full factorial experimental design is used to investigate the main effects of each parameter and the interaction effect. The obtain results show that the efficiency of the cutting process under MQL environment is significantly improved when compared to dry cutting, which proves the better lubricating performance of MQL. Besides, the feed rate and the interaction effects between the cooling lubrication modes and cutting cause the great influences on the surface roughness. Furthermore, the appropriate sets of parameters to achieve the smaller surface roughness are provided with V=70-80m/min and f =0.08 – 0.086 mm/tooth for dry condition and V=90-110m/min and f =0.08 – 0.092 mm/tooth for MQL mode.
