“…The literature reveals that when the tool life is close to its completion, the surface roughness decreases. 15,31 The experiments were mostly conducted according to the cutting tool manufacturer's recommended feed values (0.1-0.3 mm/rev). However, at the smallest diameter of the workpiece, the feed values fell slightly below the values recommended by the tool manufacturer.…”

“…The wear initiation region (first region) and accelerated wear region (third region) also vary depending on the cutting speed. Letot et al 5 suggested that the first region of the wear (the wear initiation region) was completed after a cutting time of 1 min, whereas Derani et al 15 calculated this time as 3 min. In these experiments, this time was determined to be 8 min because of the lower cutting speed.…”

“…In specific studies, it was determined that the nose wear value increased faster than the flank wear. 5,15 The flank wear measurement took place perpendicular to the cutting tool surface, and the coating of the cutting tool was challenging to analyze. For this reason, in some passes (the 212th pass, 236th pass, and In sequential measurements, the flank wear value did not increase significantly and appeared to be constant (Figure 11(a)).…”

“…The surface roughness, on the other hand, deteriorated due to the progressive cutting time. Demir and Adiyaman 17 investigated various approach angles (15°, 30°, 45°) and chip slenderness ratios (1,5,10,15) on the turning of AISI 1050 material. In addition, four feeds and depths of cut values were also used in the experiments.…”

“…They reported that an increase in all three parameters decreased the tool life, and the most significant parameter on the tool life was the cutting speed (73.59%). Derani et al 15 analyzed the tool wear and surface roughness of turning AISI 316 stainless steel material. In the experiments, it was determined that nose wear increased faster than flank wear did.…”

Machining is a complex process between the cutting tool and the workpiece, and in this process, the cutting tool constantly wears out with various wear mechanisms. Tool-wear estimation in turning is a complicated process; thus, there is a need for a study to reveal the time-dependent behavior of tool wear. In this study, tool wear and surface roughness change during the turning process of AISI 4140 steel at low cutting speeds were examined in detail with variable feed values for the first time. For this purpose, a half-minute cutting time was applied for each pass to analyze the tool wear as gradually as possible. Tool wear (flank, notch, and nose), surface roughness (Ra, Rz, and Rt), and chip morphologies were examined after each turning operation. The flank wear reached 0.3 mm, which is one of the tool life criteria according to ISO 3685, and the experiments were terminated at the 149th minute. Initially, a significant surface improvement (approx. 300%) was observed due to the decrease in feed values. In subsequent experiments, the effect of feed was significantly reduced due to increased tool wear, and limited surface roughness improvement (approx. 30%) was observed. At the beginning of the experiment, the chip breaker function of the cutting insert was successful at almost all feeds. However, in subsequent experiments, it was found that even at higher feeds, the chip breaker geometry of the insert deteriorated due to tool wear, causing changes in chip morphology, and resulting in long and undesirable chips.
