Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Springer Heidelberg, Heidelberg, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
STEP-NC-based machining architecture applied to industrial robots
(Springer Heidelberg, Heidelberg, 2019)
This paper presents a method for applying the ISO 10303-238 (AP-238) standard in robotic machining operations by using two industrial robots. The method encompasses programming, simulation and machining by industrial robots. ...
Modelling and analysis of machine tool with parallel-serial kinematics based on O-X glide mechanism
(Springer Heidelberg, Heidelberg, 2021)
Machine tools with a parallel-serial (hybrid) kinematics structures represent a compromise solution that combines the advantages of traditional serial and parallel kinematic in the building of machine tools. By selecting ...
Dynamic behaviour of cavitation clouds: visualization and statistical analysis
(Springer Heidelberg, Heidelberg, 2019)
High-speed visualization and subsequent statistical analysis of a high-speed cavitating water jet were performed with a custom image acquisition and processing system. In a cavitating water jet, cavity clouds form and ...
Multidisciplinary research method for designing and selection of bio-inspired profiles in the conceptual designing stage
(Springer Heidelberg, Heidelberg, 2021)
A multidisciplinary research method was employed with the intention to create a series of bio-inspired flattened airfoils, observe their aerodynamic characteristics, and analyse their applicability to small devices or to ...
Parametric optimization of the aluminium nanocomposites wear rate
(Springer Heidelberg, Heidelberg, 2019)
The optimization of wear rate of the nanocomposites with A356 aluminium alloy matrix, reinforced with silicon carbide nanoparticles, was performed through the analysis of the following influences: wt% of the reinforcement, ...
Boundary load distribution of simultaneously meshed gear teeth pairs
(Springer Heidelberg, Heidelberg, 2021)
The load distribution of simultaneously meshed gear teeth pairs has a significant influence in determining the relevant stress for the working capacity calculation of cylindrical gear pairs with respect to surface and ...
Simulation of compensated tool path through virtual robot machining model
(Springer Heidelberg, Heidelberg, 2020)
Nowadays, industrial robots could be a successful alternative to machine tools for milling of large parts with complex geometry. As it is known, poor accuracy which is most influenced by the stiffness of robot structure ...
Experimental optimisation of the tribological behaviour of Al/SiC/Gr hybrid composites based on Taguchi's method and artificial neural network
(Springer Heidelberg, Heidelberg, 2018)
This paper presents the investigation of tribological behaviour of aluminium hybrid composites with Al-Si alloy A356 matrix, reinforced with 10 wt% silicon carbide and 0, 1 and 3 wt% graphite (Gr) with the application of ...
Influence of secondary phases in A356 MMCs on their mechanical properties at macro- and nanoscale
(Springer Heidelberg, Heidelberg, 2020)
Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement ...
