Hardened AISI 4140 steel is widely used in automotive industries due to its high strength, high hardness, and good formability. It can be subjected to cryogenic treatments to increase wear resistance, increase the toughness and decrease the residual stress. Although many studies have been performed related to the machinability of AISI 4140 steel, the number of studies that considered four responses simultaneously are limited. In this study, the effects of cutting speeds, feed rates, and depths of cut on the vibration, motor current, machining noise, and surface roughness were investigated in turning hardened AISI 4140 steel using coated carbide insert under dry cutting conditions. Besides, the attempt was made to predict surface roughness based on machining noise, motor current, and chuck vibration during the turning process. Analysis of variance and response surface methods were carried out to analyze the experimental results and the prediction models were developed. The machining test revealed that the most effective parameter on the surface roughness value was the feed rate with a 96.07% contribution. The depth of cut and the feed rate affected vibration with 57.61% and 26.44% contribution, respectively. The machining noise was dominantly affected by the depth of cut with 76.15% contribution, it was followed by feed rate with 17.67% contribution. However, feed rate and depth of cut significantly affect motor current with 54.53% and 36.64% contribution, respectively. The graphical analysis of the effect of vibration, motor current, and machining noise on the surface roughness was presented. Based on the results, there is a direct relationship between machining noise, vibration, and motor current with surface roughness. As the level of the aforementioned responses increases the quality of the machined surface deteriorates.

In this experimental study, vibration, energy consumption, power consumption and surface roughness values that occur in the machining of AISI H11 tool steel under CO2, coolant and dry cutting conditions were investigated. The effects of different cutting parameters and cooling systems on machinability were investigated. Analysis of variance was done. Regression equations were obtained. Relationships between power consumption, vibration and surface roughness are explained with mathematical equations. Finally, the optimum CC were determined by the multiple optimization methods. According to the test results, while the instantaneous power consumption increases by increasing cutting parameters, energy consumption decreases as the processing time is shortened. Vibration value increases by increasing cutting parameters. The highest vibration value occurs in cutting with CO2. Compared to dry and CO2 cutting, the vibration is lowest in coolant cutting. The friction decreases with the coolant and the vibration value decreases. There is a similar relationship between vibration and surface roughness value. The most effective parameter on the surface roughness value is the feed rate. It was seen that the most suitable CC for the most efficient cutting, the lowest energy consumption, vibration and surface roughness value, under coolant cutting, 0.2 mm depth of cut, 175 m/min cutting speed and 0.119 mm/rev feed rate. With optimum CC, the vibration value was reduced by 5.18%, the surface roughness value by 37.12%, energy consumption by 36.19% and the machine efficiency was increased by 7.16%.

Şahinoğlu ve Ulaş, ilerleme hızı düşük, takım yarıçapı yüksek ve işleme süresi kısaltıldığında iyi bir yüzey kalitesi elde edildiğini, kesme hızı, kesme derinliği ve ilerlemedeki artış nedeniyle enerji tüketiminin azaldığını öne sürmüştür [10].

Today, dry hard turning is widely used in the processing of hardened steel due to its advantages such as low cost, high machining efficiency and green environmental protection. In this study, hard turning tests were carried out under dry cutting conditions on hardened DIN 1.2367 (55 HRC) steel material. The effect of the cutting parameters (three different cutting speeds, three feed rates and three cutting depths) on the power consumption and sound level values was investigated.
