A R T I C L E I N F O A B S T R A C T Article history: Received: 08 September, 2020 Accepted: 02 December, 2020 Online: 16 December, 2020 In this paper, the investigated results on tool wear in milling process of a Gleason spiral bevel gear was investigated. The CVD Ti (C, N)-Al2O3-TiN coated carbide inserts were used in the experimental process. The cutting inserts clamped on the tool head of Gleason tool head system. The workpiece material that was used in this study was 20XM steel. In this experimental research, the experiments were carried out according to the Box-Behnken matrix. In this study, the cutting velocity, the feed rate, and the depth of cut were selected as the input parameters for the experimental processes. By analyzing the experimental results, the influence of cutting velocity, feed rate, and the depth of cut on the tool wear in machining process was investigated. Besides, the tool wear was successfully modelled as a quadratic polynomial function of the cutting velocity, the feed rate, and the depth of cut. Moreover, the optimization process was also conducted to determine the optimal values of input parameters. In this case, the minimum value of the tool wear that was 32.3679 μm was achieved at the cutting velocity of 93.0 m/min, at feed rate of 59.3939 s/tooth, and at the cutting depth of 0.553 mm. The obtained optimal values that were successfully verified by cutting test process. The difference between predicted and experimental values of tool wear was 2.9 %. This experimental method could be used to reduce the tool wear in the milling process of a Gleason spiral bevel gear.
