Experimental and Numerical Study of Thermal Conditions in Magnesium Alloy Milling

The aim of the scientific activity was to determine the effect of milling process parameters such as: technological parameters (cutting speed vc, feed per tooth fz, depth of cut ap) and tool tip geometry (different rake angles γ) on the chip temperature in the cutting zone. An additional aim of the research was to determine the interdependencies between the technological parameters and the tool geometry. As a result of the simulations, it was also possible to develop process models, which allows for the forecast of the maximum temperature in the cutting zone when the machining parameters are known. The scientific activity was aimed at gaining new knowledge about the phenomena and observations concerning the chip temperature in the cutting zone during the "dry" milling of magnesium alloys. Selected magnesium alloys (AZ31 and AZ91D) belong to the group of materials for which there are certain limitations related to the risk and danger of ignition during processing, however, due to the interest in these materials of many contemporary researchers, their analysis is important, hence such a choice. In addition, the possibility of carrying out "dry" machining processes allows for the elimination of machining liquids, which has a positive effect on the environment. Milling was performed on the AVIA VMC 800HS machining center. Chip temperature measurements in the cutting zone were carried out using a high-speed FLIR SC 600HS thermal imaging camera.The data deposited in repository are as *.csv format and *ods open format. The data included concern the change of cutting speed, AZ91D alloy and the two tools used (gamma 5 and gamma 30).
