“…It characterises the dispersion of the results obtained and it can be determined on the basis of two methods, i.e., A and B. The uncertainty component of A method is based on the statistical analysis of the measurement results, i.e., the calculation of the standard deviation of the mean, while the uncertainty component of B method takes into account the data included in the calibration certification of the measuring instrument used [ 3 , 30 ].…”

“…When manufacturing such parts, major difficulties arise in retaining appropriate dimensional and shape accuracy, since undesirable deformations appear after the completion of cutting and removal of the clamping force [ 1 , 2 ]. For this reason, measuring the cutting force, which is one of the factors connected to the aforementioned problem is an important aspect [ 3 ]. It should also be noted that due to the need to obtain high efficiency, High Speed Cutting is a widely used technique which is characterised by lower depth of cut a p and higher cutting speed v c compared to conventional machining [ 4 ].…”

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.
