In the industry, the concept of “production quality” means a very important and inseparable role, which has a large share in the final quality of the product. Various factors affect product quality. Above all, state-of-the-art technologies are used in every industry, which helps to adapt quickly and efficiently to changes in market conditions, which has a significant impact on the competitiveness of manufacturers to become market leaders. The manufacturers ‘efforts are made to produce a flawless product that will excessively meet customers’ requirements for the perfect product. An integral part of the production process is the quality control of products at certain stages of production. Measurement requirements are defined by satisfactory accuracy, variability, total cost and speed. An important factor in product inspection is currently the creation of a three-dimensional virtual model of a real product, where you can easily compare the created 3D model with the original CAD model and display dimensional deviations.

A cylinder bundle is a portable assembly which consists of a frame and two or more cylinders, each of a capacity up to 150 l and with a combined capacity of not more than 3000 l, or 1000 l in the case of toxic gases, connected to a manifold by cylinder valves or fittings such that the cylinders are filled, transported and emptied without disassembly. The type approval of the cylinder bundle covers series of tests regarding its structure and its behavior during and after the tests. The research, presented in this paper, is focused on virtual testing, i.e. modeling and simulation of a cylinder bundle drop tests. First, a CAD model of a cylinder bundle which contains five cylinders is built, and then a vertical and rotational drop tests are simulated in virtual environment. The obtained results are analyzed in line with the demands defined in the international standard ISO 10961:2010(E).They could serve as a base for further improvement of the model and point out the possibility for validation of the virtual testing.

A work environment for modelling, simulating and performing various technological operations (milling, drilling, etc.) has been created using hardware developed to include a Fanuc M430i-A/4FH robot and specialised software Roboguide. As a result of the study, guidelines have been developed for the software and hardware improvement of the system in order to enhance its use both for the purposes of training and research.
