Еxpeгimental investigаtion of сutting cоnditions рarameters on surfаce roughness in aluminum alloys (AL-2024)

The purpose of this search is to study the main factors on surface roughness in (AL-2024) using a CNC milling machine for an HSS tool with flat end milling. And by Taguchi experience design method conserve time and costs. To determine optimal values ​​of optimization. We then performed analysis variance regression. Confirmation tests were verify work. cutting process consists two stages; first stage upper direction cutting, coolant dry cutting. second lower cut, results show best operating condition obtain product bottom grinding, measuring conditions cutter (feeding) = 15 mm/min), (cutting depth 1 mm) speed 37.68 (m/min) (Ra 0.17 µm) compared other value obtained.
