Various aluminum alloys (2011-T8, 3003-H14, 4032-T6, 5056-H14, G67-T6, 7075-T6 and Al-17%Si-T6) were turned with K10 and diamond compact tools to examine the cutting behavior under wide range of cutting conditions. The effects of mechanical properties (hardness, tensile strength shear stress of high temperature and coefficient of friction for K10 tool against work materials) of these alloys on cutting forces, chip forms and finished surface roughness were discussed. Chip forms and cutting forces depended on the coefficient of friction on the rake face of K10 tool at high temperature. Cutting forces and chip forms cut with diamond compact tool differed from those with K10 tool. |
