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.
