	Magnesium alloys are construction materials with increasing application in current industry. The increasing share of this group of materials in various industries increases the need for continuous development and improvement of machining processes. Due to the negligible share of abrasive machining in the processes of shaping magnesium alloys elements, it is necessary to achieve the highest possible accuracy by milling. The conducted research is to determine the feasibility of the precision milling process of magnesium alloys with the use of coating tools. The aim of the performed study was to analyse the influence of the tool coating type and the change of technological parameters on the surface texture, analysed based on a wide range of surface roughness parameters. Milling tests on samples made of the AZ91D magnesium alloy were carried out using three-edged end-mills with a diameter of 16 mm and with applied TiB2 and TiAlN tool coatings. The values of the basic technological parameters: cutting speed, feed per blade and axial depth of cut were also used as variable factors.The result of the performed research was information on the values of a wide range of surface roughness parameters measured on the specimen surfaces obtained after milling under precision machining condition. Analysis of the results showed that the main influence on the machined surfaces had a change in cutting speed and feed per tooth. However, the change in axial depth of cut had the least effect among the technological parameters. The application of a TiB2-coated tool also proved more beneficial. Based on the conducted research, it can be concluded that cutting tools with protective coatings can be successfully used to realise the precision milling process of the AZ91D magnesium alloy. High surface quality was achieved during machining, which is indicated by the low values of the measured surface roughness parameters.
