“…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 ].…”

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.

ISO 9283 is a significant guiding standard for assessing the performance characteristics of robots. The main objective of the present paper was to verify the repeatability of the Panasonic TM-2000 welding robot at a manufacturing company. The paper describes the workflow of the robot control program in the simulation software RoboDK, which created a complete welding station. The measurement, as well as the simulation, were possible thanks to designing the measuring device, the imaginary ISO cube, the measuring plane, the measuring points, and last but not least, the cycle that determined in which order the points were measured. The analytical part of the paper resulted in a direct measurement of the position repeatability of the welding robot. A total of five points were measured for the X-axis and five points for the Y-axis. Each point was recorded 30 times, with measurements taken in the positive direction of motion. The results were compared with the value given by the manufacturer, and the measured deviations were presented graphically.

“…Verification via a telescopic ballbar offers a relatively easy and fast check of CNC-machining machines positioning according to globally recognized ISO and ANSI standards [12]. The ISO 230-1 standard mentions the ballbar as the regular tool, which made it the most frequently used tool for verifying the properties of not only industrial robots [13,14]. It offers troubleshooting that enables problem detection, thus making it possible to identify the source of error.…”

This study describes the design of an experimental methodology developed to measure the working properties of the accuracy of the path traversed by a collaborative robot. The methodology proposed here uses a collaborative robot and a laser measuring system Gepard from Raytec. The main parts of the measuring chain and the ISO 9283 standard are described. The proposed experimental methodology should examine the working properties of industrial robots, such as position and path. The focus of this study lies in the path accuracy of robots. Currently, interest in this topic is on the rise, and the measuring systems capable of recording this parameter are too costly. This study focuses on the experimental measuring of the path properties, describing them in more detail. The measuring and results were processed in the software tool developed for Gepard.
