“…Improving surface roughness with increasing cutting speed can be explained with easier deformation process depending on the increas- ing temperature in high speeds, easy deformation of workpiece material around cutting edge and nose radius and flowage area that is formed at these high temperatures. In addition, the easily deformed material can be formed during machining without tearing and accordingly an improvement is seen in the surface quality of the workpiece [11]. In other words, the decrease of surface roughness with the increase of cutting speed can be explained with the BUE whose formation decreases at high cutting speeds.…”

In this study, the effects of microstructure differences obtained with the application of different spheroidizing heat treatment cycles on medium carbon steel on cutting forces and surface roughness values were investigated. For this purpose, a group of AISI 1050 materials was annealed at 700• C below Ac1 temperature for 720 min and cementite phases were spheroidized by the traditional method. Another group of materials was quenched after austenitization at 850• C for 15 min and then cementites were spheroidized in the ferrite matrix by over-tempering separately at 600• C for 15 and 60 min and at 700• C for 60 min. Machining of the samples was tested under dry cutting conditions in CNC turning center with SNMG 120408 cementite carbide cutting tool and proper PSBNR 2525M12 tool holder with 75-degree edge angle. Cutting forces of traditionally spheroidized samples were lower than the samples spheroidized after quenching. In addition, their cutting forces decreased due to the increase in the average sizes of spheroidal cementite. Minimum surface roughness value was obtained from the samples which were spheroidized at 600• C for 15 min after quenching. However, surface roughness rate of the sample increased as spheroidizing time increased. K e y w o r d s : spheroidizing, cutting forces, surface roughness, medium carbon steel

“…Yüzey pürüzlülük değerinin iyileştirilmesi için kesme hızının arttırılması, literatürde kullanılan en yaygın yöntemdir [21]. Kesme hızının artması ile iyileşen yüzey pürüzlülüğü, yüksek hızlarda artan sıcaklığa bağlı olarak, deformasyon işleminin kolaylaşması, iş parçası malzemesinin, kesici kenar ve burun yarıçapı çevresinde rahat bir şekilde deforme edilmesi ve bu yüksek sıcaklıklarda oluşan akma bölgesine bağlı olarak açıklanabilir.…”

“…As per finishing operations are considered criteria like surface finish and chip breakability are considered for machining performance measures. Chip size and shape are two important factors covered under chip breakability [7]. Artificial neural network approach can also be used as multi-response technique for cutting condition optimization.…”

Economical machining operation plays an important part in competitiveness in the industries therefore selection of optimum cutting parameters is of great concern in manufacturing environments. The current research is aimed at fixing the optimal process parameters for hard turning of aluminum in CNC lathe machine using carbide tool as per the machinability aspects. On the basis of three-factor-three-level L9 orthogonal array, trials are performed by varying the manageable process constraints which are spindle speed, depth of cut and feed rate. Performance of machining has been figured by several responses like Surface Roughness and Material Removal Rate. Towards optimization above mentioned performance factors are treated as purpose functions, assuming that it corresponds to Higher-is-better and Lower-is-Better requirement respectively. Satisfaction function approach is used in this paper to find out satisfactions of individual responses enabling gathering of multi-responses into a comparable sole index
