Abstract Machining is a method of material removal by mechanical wear, which is widely applied in the industry for the creation of parts and objects. In this sense, when it comes to drilling, the chromium-based coating is important to improve the life of the drill bits, and to reduce manufacturing costs. This feature is constantly used in the aeronautical sector for machining of the aluminum alloy Al-7075, but also in other areas such as automobile industry. However, there is a gap of knowledge about the real effectiveness of this type of tool in different materials, which puts the life of the drill at risk.Inside this context, and knowing that the analysis of chromium-coated drills is a relevant importance for the industry, this project aims to study this drilling tool in different materials, in order to ascertain the wear of this type of coating. For this, the Taguchi methodology will be implemented, with the objective of maximizing the experimental procedures and, obtaining accurate results with minimum possible tests. Furthermore, it will be possible to understand how the chromium-coated drill behaves when subjected to different substrates. Thus, this study aims to carry out mechanical drilling tests on 7075 aluminum, 15-5PH stainless steel and 1045 carbon steel parts. | |
