Özet
In this study, the surface roughness (R-a) and vibration (Vib) during finish turning of AISI 4140 (52HRc) steel workpiece under cooling method were investigated as experimental and statistical. Taguchi method was used in statistical investigation of obtained data from the finish turning experiments. As cutting parameters, cutting speed: 160, 200, 240 and 280m/min, feed rate: 0.08 and 0.16mm/rev, depth of cut: 0.15 and 0.3mm, and cooling method: dry/wet were selected for this experimental study. Vibration values during finish turning of steel workpiece were collected online by accelerometers and R-a measurement device was used to obtain the R-a values. Optimum R-a and Vib values were obtained in finish turning of this workpiece. The cutting parameters determined for optimum R-a values were obtained as 0.08mm/rev of feed rate, 200m/min of cutting speed, wet turning process of cooling method, and 0.30mm of depth of cut. Optimum Vib values were obtained as 0.08mm/rev, 240m/min, dry turning and 0.15mm. Experimental results for the lowest R-a and Vib were found as 0.219 mu m and 0.003463gRMS. The predicted values for the R-a and the Vib were 0.222 mu m and 0.003328gRMS, respectively.
