“…Some benefits of automation are reduced internal costs of manufacturing, increased operation efficiency, improved product quality, decreased labour intensity and nuisance, and higher safety. In addition to the ever increasing requirements regarding the precision and control range of both position and speed, as well as movement dynamics, expectations also increase with regards to the flexibility of the means of productions, understood as the possibility of easy and relatively quick adjustment to changing manufacturing tasks [3,4,5,6]. Combining all these aspects is very difficult and it would even be impossible without the achievements of the microelectronic industry.…”

The article presents a numerical control system of a multi-axis machine built using a programmable logic device.The system consists of PC, motor controller (based on FPGA), power stages and motors. The complete code of controller was written in the VHDL language and implementing in Xilinx Spartan 3 board. The PC program was created using LabVIEW.The logical and functional tests of the system have been carried out. The application of a programmable device enables its quick configuration according to the requirements set by the user.The main advantage of FPGA is the option to expand to following modules, such as the incremental encoder support module, PWM, FOC etc. In these applications, the advantage of the programmable system becomes visible, which due to its specifics, is built for parallel processing or generating signals.

“…Onyx is a nylon-based material with improved mechanical properties, owing to the impregnation of carbon microfibers. Bárnik et al [ 18 , 19 ] studied the effect of infill pattern and density on 3D-printed Onyx samples’ mechanical properties. A rectangular pattern with an even number of layers revealed optimum mechanical performance; however, this infill pattern added the most towards overall volume.…”

The commercial availability of 3D printers for continuous fiber-reinforced 3D-printed (CFR3DP) composites has attracted researchers to evaluate the thermomechanical properties of these materials. The improvement of strength through chopped or continuous fiber reinforcements in polymers could provide remarkable results, and its exploration can provide broad applications in several industries. The evaluation of mechanical properties of these materials at elevated temperatures is vital for their utilization in severe operating conditions. This study provides insight into the effect of different fiber reinforcements (Kevlar, fiberglass, and high-strength high-temperature fiberglass) and temperatures on the creep and recovery behavior of CFR3DP Onyx composites. Experimental results were also compared with analytical models, i.e., Burger’s model and Weibull distribution function, for creep and recovery. Results from analytical models agreed well with experimental results for all the materials and temperatures. A significant drop in maximum and residual strains was observed due to the introduction of fibers. However, the creep resistance of all the materials was affected at higher temperatures. Minimum creep strain was observed for Onyx-FG at 120 °C; however, at the same temperature, the minimum residual strain was observed for Onyx-KF. Based on the analytical models and experimental results, the role of fiber reinforcements on the improvement of creep and recovery performance is also discussed.

“…Three-dimensional printed parts show different properties depending on other AM techniques [2]. Fused deposition modeling (FDM), selective laser melting (SLM), multi-jet modeling (MJM), laminated object manufacturing (LOM), and stereolithography (SLA) and selective laser sintering (SLS) are various additive manufacturing (AM) methods [3][4][5][6][7][8]. Additive manufacturing provides the ability to produce complex geometries that are difficult to produce by conventional methods without complex tooling.…”

Mathematical Modeling and Optimization of Fused Filament Fabrication (FFF) Process Parameters for Shape Deviation Control of Polyamide 6 Using Taguchi Method

et al. 2021

Fused filament fabrication (FFF) is a layer-by-layer additive manufacturing (AM) process for producing parts. For industries to gain a competitive advantage, reducing product development cycle time is a basic goal. As a result, industries’ attention has turned away from traditional product development processes toward rapid prototyping techniques. Because different process parameters employed in this method significantly impact the quality of FFF manufactured parts, it is essential to optimize FFF process parameters to enhance component quality. The paper presents optimization of fused filament fabrication process parameters to improve the shape deviation such as cylindricity and circularity of 3D printed parts with the Taguchi optimization method. The effect of thickness, infill pattern, number of walls, and layer height was investigated as variable parameters for experiments on cylindricity and circularity. The MarkForged® used Nylon White (PA6) to create the parts. ANOVA and the S/N ratio are also used to evaluate and optimize the influence of chosen factors. As a result, it was concluded that the hexagonal infill pattern, the thickness of 5 mm, wall layer of 2, and a layer height of 1.125 mm were known to be the optimal process parameters for circularity and cylindricity in experiments. Then a linear regression model was created to observe the relationship between the control variables with cylindricity and circularity. The results were confirmed by a confirmation test.
