摘要：An aspect of a set of hard turning experiment conducted on 41Cr4 alloy steel to investigate the influenceof the machining, cutting tool and work-piece variables on the machining induced vibration and surface roughness ispresented. The response surface methodology, based on central composite design of experiment was adopted. Analysisof the response data was performed in the Design Expert 9 environment. The obtained Quadratic regression modelswere evaluated for the machining induced vibration and surface roughness as functions of the work-piece overhang,feed rate and depth of cut. The influence of the factors on the response variables were established through analysis ofvariance.The optimal settings of these factors as are required to minimize the response variables were also determine. Itwas found that the optimum setting of80 mm, for the work-piece overhang; 0.15 mm/rev, for the feed rate; and 2.32666mm, for the depth of cut would minimize the machining induced vibration of the cutting tool to a value of 0.12 mm/s2,and the surface roughness of the specimen work-piece to a value of 5.21111 μmm while keeping other operating factorsconstant at their intermediate levels within the experimental design space.
