Cutting Force during Surface Layer Milling of Selected Aluminium Alloys

Abstract

This paper presents the analysis of cutting force during surface layer milling of selected aluminium alloys, which are widely used in the aviation industry. The cutting force is one of the most important parameters determining the machinability of the material and also provides important information about the course of the cutting. The study analysed the influence of the technological parameters, i.e., cutting speed vc and depth of cut ap as well as the relation between cutting tool feed direction and rolling direction on the value of cutting force during milling of selected aluminium alloys, i.e., EN AW-2017A T451 and EN AW-2024 T351. The material anisotropy is a very important issue, since the engineering industry faces enormous problems related to the cutting of the tested materials that are usually supplied in the form of rolled plates. The surface layer was cut due to the fact that it accumulates the greatest residual stresses. The measurement process of cutting force was performed by using 9257B Kistler piezoelectric dynamometer. As part of the analysis of the results, the measurement uncertainty was also estimated, which was determined on the basis of two components obtained by using the A and B methods, respectively.

Effect of Ceramic Brush Treatment on the Surface Quality and Edge Condition of Aluminium Alloy after Abrasive Waterjet Machining

“…Ceramic brushes are characterized by low force value, which is desired when machining thin-walled components with reduced rigidity. Problems connected with machining thin-walled components are described in [18,19].…”

Analysis and prediction of the impact of technological parameters on cutting force components in rough milling of AZ31 magnesium alloy

“…There are also studies investigating power demand in the milling of different materials, including magnesium alloys. Compared to other metals [2], the milling of magnesium alloys can be done in an effective way due to the possibility of applying high values of the technological parameters of the milling process [3], both during the square shoulder milling and roughing plunge milling process [4]. For instance, unlike in the case of Al-Si alloys, the cutting force generated in the milling of magnesium alloys is lower by approx.…”
