Abstract : Metal cutting processes have an important place among traditional manufacturing methods. The most important parameters in this type of manufacturing are the cutting tools used in manufacturing. Tool wear, which is the most important parameter affecting the performance of cutting tools, is of vital importance in terms of tool life. The present study sought to find the parameters that affect the position of the initial wear. The evaluation was conducted during the first spreading effect of tool wear (0-10 s). The experimental results showed that significant flank wear was the predominant failure mode affecting the tool life. The workpiece material was AISI 1050 steel, and three different types of DNMG 150608 carbide inserts, having the same geometry and substrate but different coating layers, were employed. Flank wear measurements were taken after the first few revolutions and the experimental results clearly showed that wear occurring at the beginning of the cutting process was very slight (0.04 mm).However, in industry, tool life criteria have been established as 0.3 mm flank wear for the coated tools used in the study.This is vitally important information which can facilitate the assessment of tool life.

Keywords : Initial, Ttool Life, Coating, Machining, Flank Wear.
