| VERISCAN – Metrological framework for the verification of dynamic 3D scanning systems according to ISO GPS in digital manufacturing | |
| Metrologický rámec verifikácie dynamických 3D skenovacích systémov podľa ISO GPS v podmienkach digitálnej výroby | |
| Program: | APVV |
| Duration: | 1.9.2026 – 31.8.2029 |
| Project leader: | Doc. RNDr. Witkovský Viktor, CSc. |
| Annotation: | The project addresses the lack of a comprehensive methodological framework for the verification of handheld 3D scanning systems. Despite their massive implementation in digital manufacturing (Industry 4.0/5.0), their metrological assurance lags behind technical hardware capabilities. The core scientific challenge is the missing link between the variable nature of handheld scanning (operator influence, trajectory, strategy) and the strict requirements of the Geometrical ProductSpecifications (ISO GPS) system.The objective is to research and develop a metrological framework that transforms handheld 3D scanning from avisualization tool into a full-fledged system for product conformity decision-making. The project focuses on developing specialized reference artifacts with complex geometry designed for dynamic optical systems. It uniquely combines the technological expertise of UNIZA in digital quality control with the fundamental metrological competencies of the Institute of Measurement SAS in calibration and uncertainty estimation (GUM).The original contribution is an ISO GPS-oriented verification methodology that systematically integrates dynamic measurement uncertainty sources into final conformity assessment. The outputs include a physical reference artifact with SI traceability and verified procedures for the automotive and machinery industries. The project directly supports digital manufacturing chains by enhancing production quality and reducing non-conformance costs through metrologically correctvalidation of complex components. |
| CICPE – Cockroaches in complex past ecosystems | |
| Šváby v komplexných pravekých ekosystémoch | |
| Program: | APVV |
| Duration: | 1.9.2026 – 31.8.2028 |
| Project leader: | RNDr. Hain Miroslav, PhD. |
| Annotation: | Cockroaches, together with their predatory descendants, praying mantises, and social themes, have been pillars ofecosystems for more than 300 million years, primarily through the decomposition of biomass – they have no substitutes in this. New discoveries make it possible to grasp their evolution in a broader context and to the extent to which they influence the cycle of individual elements during the geological scale. Therefore, the samples in this project, in addition to the detailed frontier evolutionary analysis, also include complex geological, physical and chemical analysis and knowledge applied to entire ecosystems. The project benefits from global cooperation and possibly already processed material from around the world, which will represent not only almost 10% of the latest knowledge, but all groups are already included inthe appropriate system. Such work has no parallel in other terrestrial groups and is based on 110,000 samples, of which 4,000 are represented by various ambers, including those from the time of dinosaurs. This year\’s research has already been published in high impact (NSR IF= 20.7) and therefore this study is promising. In addition to science and wide popularization (over 40,000 students), the project will also create a new job and provide part-time jobs for exceptionally talented high school students who would otherwise end up abroad and/or in a commerce. |
| ARAM – Research of reference standards and measurement methods ensuring determination of the relationship of geometric specifications and qualitative indicators of 3D objects created by additive technologies | |
| Výskum referenčného etalónu a meracích metód zabezpečujúcich určenie vzťahu geometrických špecifikácií a kvalitatívnych ukazovateľov 3D objektov vytvorených aditívnymi technológiami | |
| Program: | APVV |
| Duration: | 1.7.2024 – 31.12.2027 |
| Project leader: | RNDr. Hain Miroslav, PhD. |
| Annotation: | The present project is aimed at evaluating the quality of additive manufacturing, a reference test artefact designed and developed for this purpose. The development of the reference artefact and the quantification of its parameters will make use of the latest knowledge in additive manufacturing, state-of-the-art measurement strategies implemented using X-ray microtomography, magnetometry, coordinate measuring devices, optical and electron scanning microscopes and methods of mathematical-statistical processing of measured data. Additive manufacturing technologies are capable of producing parts with very complex geometries that conform to the desired design without further machining. It is for this reason that they are very promising and their use in industry is growing. In order for additive manufacturing products to fully replace conventionally machined parts, they must meet the required quality criteria such as shape and dimensional accuracy, surface roughness, internal defects, residual stresses, etc. The final quality of parts produced by additive manufacturing technology is influenced by the characteristics of the raw material and the parameters and settings of the system. The aim of the project is to investigate the production of modified monofilaments and the measurement methods necessary for the realization of a stable and reproducible reference test artifact, which would be used to assess not only the geometric capability of additive manufacturing systems but also the internal structure and selected properties of the final product. |
| METIM – Design of a Methodology and its Verification for the Measurement of Selected Parameters of Ti Implants in the Manufacturing Process | |
| Návrh metodiky a jej overenie pre meranie vybraných parametrov Ti implantátov vo výrobnom procese | |
| Program: | APVV |
| Duration: | 1.7.2023 – 30.6.2027 |
| Project leader: | RNDr. Hain Miroslav, PhD. |
| Annotation: | The project focuses on the development and application of measurement and non-destructive testing methods inthe manufacturing of titanium dental implants. Dental implants are medical devices that have to comply with thetechnical requirements given by regulation of the European Parliament and Council EU 2017/745 from 5 Apr 2017.Under this regulation, among other obligations, the manufacturer must ensure that these devices are safe andeffective and do not compromise the clinical condition or patients safety. The dental implants should also meet ahigh level of health and safety protection, taking into account the generally accepted state of the art in science andtechnology. In this project we will address the requirements related to the design and manufacturing and inparticular: the compatibility of the different parts of the device, the influence of processes on the properti es of thematerials, the mechanical properties of the materials used such as strength, ductility, resistance to wear andfatigue, the properties of the surfaces, and confirmation that the device meets all defined physical specifications aswell as the identification of contaminants in the manufacturing process. To ensure these requirements, we intend touse state-of-the-art measurement methods such as X-ray microtomography (microCT), scanning electronmicroscopy (SEM), optical measurement of surface roughness, SQUID magnetometry. Since the abovemeasurement methods are time consuming and do not allow their full application in the production, the solution willalso include the design of effective methods of statistical quality control, which will be applied at the manufacturerof dental titanium implants MARTIKAN, s.r.o. The objectives of the proposed project correlate with the Researchand Innovation Strategy for Smart Specialisation of the Slovak Republic 2021-2027 (SK RIS3 2021+), while theyaffect two defined domains, namely Innovative Industry for the 21st Century and Healthy Society. |
