Kiedy dwa lata temu pandemia zaatakowała społeczeństwo współczesnego świata, mało osób przypuszczało, że przyjdzie nam żyć z nią przez dłuższy czas. A jednak tak właśnie się stało. Życie wielu z nas zmieniło się bardzo wyraźnie. A co w tym czasie działo się w świecie metrologii długości?

The article presents the analysis of the influence of various fixtures of the Y-axis slide of the CMX 70U machining center measured in a coordinate measuring machine. As a result of a series of measurements of the designated geometric features, specific deviations were determined, and statistical calculations were performed on their basis. The further part of the article shows the analysis of the theoretical body deflection under the influence of the force of gravity performed using the MES method in CREO Simulate.

The article presents the results of analyzing the surface roughness of samples manufactured using the PolyJet additive technology. Three types of photopolyacrylic resins were used in the production process of the test samples. The samples were measured using stylus and optical measurement methods. The presented research extends information on the surface roughness of resins used in the PolyJet 3D printing process. It is a starting point for further improvement of measurement procedures for polymer materials.

Contact stylus profilometry is the leading surface texture measuring method in many manufacturing industries. For years it has been unmatched in terms of accuracy and reliability. Advancements in technology have led to the improvements in the profilometer design. A stylus can either have a built in skid or be skidless. In this study, the influence of skid on the measurement accuracy and repeatability was evaluated. Four different contact stylus profilometers were used to measure three standard roughness artifacts each. Every set of measurements consisted of 50 repetitions of the same profile, with the same parameters. Out of these profiles, five roughness parameters were calculated and were subjected to a statistical analysis. Relative errors of these parameters were also considered and presented individually for each roughness standard. Researchers found differences in the measurement results dispersion of various roughness parameters between the three roughness standards. The presented results of the measurements clearly indicated that there is a dispersion of the obtained values for the older type of contact stylus profilometer (P1, skid). The skidless portable devices, P2 and P3, have better measurement resolution, which results in a noticeably lower dispersion of measured values. A tabletop, stationary device utilizes a skidless measuring probe. It has both the best resolution and the highest rigidity, which results in the lowest dispersion of measured values. The lowest relative error of the Ra parameter was determined for the P2 device (9.2%) and the highest was determined for the P3 device (72.6%).

The paper presents an analysis of the influence of the Shelf Ready Packaging (SRP) machine performance parameters on the repeatability of generated cardboard boxes’ selected geometric features. As part of the research, two batches of packaging were measured. Each batch contained 100 pieces of packaging, manufactured either at a rate of 15 pcs/min or 20 pcs/min, 50 pcs each. Both batches were measured using Creaform’s Academia scanner using VXelements 6.2 software. The results were analyzed using GOM Inspect programming. In the first stage, the geometric repeatability of the products was analyzed on the basis of two selected critical features, which were considered to be the internal length and width of the cardboard packaging. These features are responsible for the proper efficiency of the packaging and the possibility of combining cartons during transportation. The results obtained were subjected to statistical analysis. In the second stage of the research, an analysis of surface deviation maps was carried out against a reference element. Our findings allow it to be concluded that increasing the production output of carton packaging (from 15 to 20 pcs/min) did not negatively affect the dimensional accuracy and repeatability of the process. It was also found that the shortening of packaging production time by increasing productivity had a positive effect on the stability of the manufacturing process of hot-glued SRP packaging.
