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