AISI 5115 is widely used in engineering applications such as manufacturing of shafts, gears,
machine components and cutting tools due to high strength, toughness and machineability. Turning,
milling and drilling operations are mostly preferred including heat treatments on AISI 5115. In this study,
the effect of three key cutting parameters on the turning behavior of AISI 5115 steel was investigated. A
full factorial design with the variables of feed rate (0.1 and 0.15 mm/rev), depth of cut (0.2 and 0.3 mm)
and, cutting speed (40 and 60 m/min) was employed. Turning operations were performed using CCMT-
09T308-304 cutting tool at a machining length of 200 mm with eight samples under dry conditions.
Experiments shows that the Maximum temperature is achieved on 0.15 mm/rev feed rate, 0.3 mm depth
of cut and 60 m/min cutting speed. Reduction on cutting speed to 40 m/min results in decrease in
temperature about 13 oC. Similarly, the temperature decreases on each sample with lower cutting speed
when the feed rate and cutting speed is constant. The variation in feed rate from 0.1 to 0.15 mm/rev
showed no noticeable effect on the temperature when the depth of cut and cutting speed were fixed at 0.2
mm and 40 m/min, respectively. In addition, varying the depth of cut had little effect on the temperature
at a feed rate of 0.1 mm/rev; however, a significant increase in temperature was observed at a feed rate of
0.15 mm/rev.
