The Influence of the Type of Coating on the Cutting Tool Wear During Turning Of 316L Austenitic Stainless Steel

Abstract

The paper presents the influence of coatings applied with the use of PVD method on cutting tools on the wear of the tool and compares it with an uncoated P25 cemented carbide plate. During the experiment, two types of TiAlN coatings were used, applied in various proportions, as well as TiN coating. During the tests, the average width of the wear band on the flank face in B VBBzone and the width of KBcrater were monitored. Moreover, the scanning analysis of the tool was conducted in order to determine the intensity of adhesive wear. The lowest values of selected tool wear indicators were found out with the use of TiAlN coating applied in eight layers in the proportions 33/67% -TiN/TiAlN. The scanning analysis proved the highest adhesive wear of the uncoated P25 cemented carbide plate, as well as increased abrasive wear of the flank face and the formation of a crater in comparison with coated plates.

Innovative Comparison on the Performance of TiCN Coated Drill Bit and Uncoated Drill Bit in the Novel CNC Drilling of LDX 2205 Duplex Stainless Steel for Maximizing Material Removal Rate

“…From the graph it is proven that the coated tools give better MRR than the uncoated tools (Bhanu Prakash and Thiagarajan 2021). This is due to higher hardness, better abrasion resistance and high material adhesion of TiCN coated cutting tools (Maruda and Szczotkarz 2016). The results of the above researchers are in compliance with the findings of this study.…”

Innovative Comparison on the Performance of TiCN Coated Drill Bit and Uncoated Drill Bit in the Novel CNC Drilling of LDX 2205 Duplex Stainless Steel for Minimizing Roundness Error

“…This conflict arises due to the reason that machining parameters were varying by the researchers in each drilling process in order to reduce the roundness error but in this research the input parameters were kept constant and used coated tools (TiCN drill bit) to bring minimum RE. In the novel drilling process the machining parameters play an important role (Maruda and Szczotkarz 2016). In this research the machining parameters like cutting speed, feed rate, type of tool are the factors which affect the result (RE) of this study.…”
