AB  - Applying nanofluid formulates using dispersions of nano Aluminum Oxide (Al<sub>2</sub>O<sub>3</sub>) in normal oil may 
decrease the Total Cutting Force (TCF) in the gear hobbing because the nearly spherical Al<sub>2</sub>O<sub>3</sub> nanoparticles 
easily entry into the contact area friction to decrease the friction. However, the gear hobbing is very
complicated, difficult to measure TCF and has the high cost for an experience. Therefore, a fly-hobbing process
was used to perform cutting on a milling machine so that the size of chip produced was the same as the largest
cutting chips produced during the hobbing process. This study focused on the fly cutting process of SCM420
steels using cutting fluid mixed Al<sub>2</sub>O<sub>3</sub> nanoparticles. The influence of the parameters on TCF was evaluated 
through the mean value and ratio (S/N) by Taguchi&#146;s method. The results indicated that nanoparticles size,
nanoparticles concentration and interaction between them were the most significant parameters that influenced
TCF of fly hobbing. The nanoparticle size 20 nm showed a minimum TCF lower 13.2% than nanoparticle size
135 nm. Using cutting fluids added 0.5% Al<sub>2</sub>O<sub>3</sub> nanoparticles can reduced the TCF by 17.6% as compared with 
0.1% Al<sub>2</sub>O<sub>3</sub>.
