Verification of the Random Nature of the Experimental Data in the End-Milling Process of Aluminum Alloys

From a theoretical point of view, the research carried out in this manuscript was carried out starting from the study of the links between surface roughness and cutting speed, cutting depth and feed per tooth in the end milling process. From an experimental point of view, it started from the organization and development of the physical cutting process, the cutting regimes to be analyzed were established, after which the surface roughness was determined and measured. In this way, the connections between the factors and parameters pursued in the research resulted. The main purpose of this research is to check the random nature of the measured data related to the quality of the end milled surface of the Al7136 aluminum alloy. The main types of statistical processing performed on the sample values from the experimental measurements, the algorithms and the corresponding work modes are according to the method of research that is based on the use of the Young test. The conclusions highlighted the importance of adopting this research method and opened new directions of study.
