This paper explores the application of various machine learning techniques to model optimal measurement time required after machining with a probe on CNC tools. Specifically, research employs four different models: Elastic Net, Neural Networks, Decision Trees, and Support Vector Machines, each chosen for their unique strengths in addressing aspects predictive modeling an industrial context. The study examines as input parameters such material type, post-processing wall thickness, cutting...

Human action recognition has become a key direction in computer vision. Deep learning models, particularly when combined with sensor data fusion, can significantly enhance various applications by complex patterns and relationships from diverse streams. Thus, this study proposes new model, the Feature Fusion Graph Consecutive-Attention Network (FFGCAN), order to performance classification of main tennis strokes: forehand, backhand, volley backhand. The proposed network incorporates seven...

The availability of 3D scanning devices allows performing the process digitisation a growing number diverse museum artefacts.After properly conducted processing acquired point cloud, authors obtained photorealistic digital copy that can be presented in many ways.With regard to objects from archaeological excavations, vast majority are artefacts more or less damaged only partially preserved.Their state preservation, specialised knowledge and use appropriate computer technologies allow their...

The paper presents an analysis of the surface layer Fe-Mn-C-B-Si-Ni-Cr alloy coating after friction with C45 steel.The coatings were obtained by arc welding (GMA).Flux-cored wires used as a material.The flux-cored had diameter 2.4 mm.The tribological assessment was performed Amsler tribotester under dry conditions at unit pressures 10 MPa.The use XPS spectroscopy allowed deep profile layer.Based on results developed model for couple, hardfaced from -C45 steel.It observed that operational...

In the process of distance learning, modern information and educational solutions are increasingly employed. The introduction tools facilitating compliance with WCAG guidelines to course creators, enhances content accessibility for individuals disabilities, eliminating barriers education access. This aligns concept universal design, aiming create courses instructional materials accessible a broad audience, regardless individual needs, abilities or conditions. While this is standard in web it...

The paper concerns the research on self-organization of surface coating hypoeutectic alloy Fe-Mn-C-B modified Si, Ni, Cr, Cu with friction C45 steel. coatings were obtained by arc welding using a flux-cored wire. Tests resistance to wear carried out for use pair pin-on-disc in conditions sliding friction, model lubricating environments. surface-active (glycerol oil) and inactive (Vaseline grease) lubricant was used. Tribological tests showed that cooperation counterbody steel lubrication...

Abstract The paper discusses the aspects of potential use 3D printing technology in process manufacturing elements with different layer fillings. In technology, denser percentage filling a material, higher mechanical strength given element. However, literature on subject, dependence these parameters for additive has not been unequivocally determined. Therefore, aim study is to find correlation between internal structure understood as material produced by and impact achieved elements. To...

This paper investigates the friction process between an Fe-based coating and C45 steel with surface-active lubrication, as well examines surface before after tribological testing. As a result, it is possible to determine whether undergoes self-organization during friction. Coatings were produced by hardfacing subeutectic alloy Fe-Mn-C-B modified silicon, nickel, chromium copper. Tribological tests performed using pin-on-disc tribometer. The pin (coating) disc made of subjected heat treatment...

Tribological behaviour of coatings obtained from eutectic alloy Fe-Mn-C-B-Si-Ni-Cr was studied.The were by the method gas metal arc welding (GMA) with use powder wire.GMA is widely used for regeneration machine parts.Eutectic alloys can be to obtain high quality resistant wear and corrosion.Pin-on-disk dry sliding tests at speeds 0.4 m/s under load 10 MPa conducted pin specimens.During friction a typical tribological behavior observed.The mechanism mechanical-chemical.
