STUDY OF THE OPTIMUM CONDITIONS OF AL2O3–TIC ALLOY TURNING INSERTS FOR TURNING AISI 4140 WORK PIECES.
Keywords:
Central composite design, Surface roughness, ANOVAAbstract
In this work has object for study find the optimum condition of cutting tools Al2O3+Tic for turning steel materials AISI 4140 with automatic lathe by applying the Central composite design, CCD and analysis experimental result with analysis of variance (ANOVA)
From the study of factor, the effect on the forming consists of cutting speed at level 50 - 170 rev/min and feed rate at level 0.2 - 0.6 mm/rev it was found that feed rate Input is the main factor that has the effect surface roughness significantly (P-value < 0.05)
From analysis appropriate conditions of factor roughness is cutting speed 50 rev/min and feed rate 0.20 mm/rev found that mean roughness is 0.345 µm
