Abstract: This paper presents an approach for the optimization of laser cutting process of aluminium alloy with multi-responseoutputs based on the Grey relational analysis (GRA). For experimental design, are planned based on Taguchi’s L9 orthogonal array. The laser cutting parameters such as laser power and cutting speed are optimized with consideration of multi-response outputs such as top kerf width and surface roughness. It is observed that the laser power has stronger effect on multi-response outputs than cutting speed. According to multi-response optimization results, which are obtained from the highest value of the grey relational grade (GRG), the optimum combination is 2500 W laser power and 2.4 m/min cutting speed to simultaneously minimize the kerf width and surface roughness.

Abstract: In this paper, the experimental investigation of effect of overhang tool length, depth of cut and feed rate on two responses such as tool vibration and surface roughness, by using Taguchi method and main effect plot was performed. C45E steel bars with diameter of 88 mm were machining using different values of overhang tool length, depth of cut and feed rate. Other process parameters were constant. Taguchi method was performed in order to identify the effect of each input process parameters on the

Abstract: In this paper was analyzed and experimentally investigated two additive technologies: Stereolithography - SLA i Fused Deposition Modeling – FDM. The dimensional accuracy (deviation from the given dimensions in relation to the previously defined 3D CAD model as well as the surface roughness of the printed samples by the additive technologies FDM and SLA) was analyzed. The process parameters of these additive technologies were optimized in order to achieve better dimensional accuracy and less surface roughness on the products. Additionally, a comparison of FDM and SLA additive technologies was performed.

Nozzle Geometry - Influence on Liquid Fuel Contraction Coefficient and Reynolds

Review article, DOI: 10.18048/2019.57.02, (EBSCO).

Abstract: This paper investigates the influence of the fuel injector nozzle geometry on the liquid fuel contraction coefficient and Reynolds number. The main three fuel injector nozzle geometry parameters: nozzle diameter (d), nozzle length (l) and nozzle inlet radius (r) have a strong influence on the liquid fuel contraction coefficient and Reynolds number. The variation of the nozzle geometry variables at different liquid fuel pressures, temperatures and injection rates was analyzed. The liquid fuel contraction coefficient and Reynolds number increase with an increase in the nozzle diameter, regardless of the fuel injection rate. An increase in the r/d ratio causes an increase in the fuel contraction coefficient, but the increase is not significant after r/d = 0.1. A nozzle length increase causes a decrease in the fuel contraction coefficient. Increase in the nozzle length of 0.5 mm causes an approximately similar decrease in the contraction coefficient at any fuel pressure and any nozzle length. Fuel injectors should operate with minimal possible nozzle lengths in order to obtain higher fuel contraction coefficients.

Abstract: This paper presents the use of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to determine the optimum process parameters in plasma arc cutting of stainless steel. Two input process parameters, cutting speed and plasma gas pressure are considered and experiments are conducted based on Taguchi L9 orthogonal array. After performing the experiments, the surface roughness, cut perpendicularity and kerf width are measured. The analysis of variance (ANOVA) are performed in order to identify the effect of each input process parameters on the output responses. The results indicate that TOPSIS method is appropriate for solving multi-criteria optimization of process parameters. Results also showed that cutting speed of 2500 mm/min and plasma gas pressure of 6 bar are the optimum combination of process parameters.

Abstract: For increase of industrial competitiveness and rapid market entry with new products, various additive technologies are increasingly being used today. This paper presents the experimental results of the study the impact of the Fused Deposit Modeling (FDM) process parameters on product quality using different materials. The work is primarily focused on optimizing the important process parameters for the FDM process using the new unexplored material. The making of test samples for dimensional accuracy and mechanical properties tests was carried out on two devices, Flashforge Finder and Ultimaker 3 with two different materials: standard PLA and new composite wood (polymer + wood) material. The obtained results show that new materials that can be produced from wood waste with a certain percentage of adhesives can be used, but before that, process parameters must be precisely defined in order to achieve satisfactory quality of the final products. In this way it has a positive impact on the environment, because wood is a natural and ecologically pure material (CO2 neutral).

Abstract: For the greater use of additive technologies in the industry, research is needed to discover new materials for the rapid creation of more functional products. New materials for additive production should overcome, with their properties, all the shortcomings of the most common polymer materials. On the other hand, it is preferable for the materials to be environmentally friendly and biodegradable. This paper presents experimental research results of the additive process parameters influence of Fused Deposit Modeling (FDM) process on product quality, using different materials. Two polymeric materials, PLA and Laywoo-D3 were used for the production of the samples. The obtained results show that for certain uses of the product and certain exploitation conditions it is possible to replace the environmentally inferior materials with the new materials obtained from the wood waste with a certain percentage of the adhesive. This has a positive impact on the environment, because wood is a natural and ecologically pure material (CO2 neutral).

Abstract: The laser cutting process is a popular technology for cutting different types of materials economically. Kerf width and surface roughness are affected by laser power, cutting speed and type of assist gas. In this paper CO2 laser cutting of tungsten alloy is investigated. Statistical approach is used to analysis the impact of the process parameters on the quality characteristics. The analysis shows that the quality of the cut depends on all considered process parameters and that it is affected differently at different assist gases. Cutting speed has a stronger effect on the kerf width when used air as assist gas, while for oxygen and nitrogen the laser power has a stronger effect. Laser power has a stronger effect on surface roughness when used air and oxygen as assist gasses, while cutting speed has a stronger effect if nitrogen is used.

Abstract: Laser cutting is a popular manufacturing process utilized to cut various types of materials. There are many non-linear interaction factors responsible for the performance of the laser cutting process. Identification of dominant factors that significantly affect cut quality is important. In this paper, the effect of the process parameters is analysed on the laser cut quality of an uncommon alloy, the tungsten alloy sheet with thickness of 1 mm. The experiments are conducted at three levels of the selected process parameters such as assist gas type (oxygen, air and nitrogen) and assist gas pressure. Taguchi design of experiments is used to obtain the optimum conditions through the study of signal to noise ratio for three quality characteristics such as kerf width, heat affected zone and surface roughness. Results of this study indicate that the optimal assist gas pressure is entirely different for kerf width, heat affected zone and surface roughness. The nitrogen as assist gas is suggested as the optimal assist gas for all of three quality characteristics.

Abstract: Layered manufacturing technology allows rapid production of parts, which can be used for various engineering evaluation and analyses. For that reason, there is a need for developing an expert tool to fully implemented analyses of a CAD model at the some phases of design process. This paper introduces multi criteria decision based on intelligent advisory system. Knowledge base contains collected experts recommendations from functional, aesthetic and ergonomic field. These recommendations are improving model characteristics for its better exploitation. The ultimate goal of this expert tool is to provide the highest level of advice, depending on the limitations, such as surface quality, time production, manufacturing, assembling, or geometrical complexity. This model system should be applicable for the most CAD models. A case study with the electrical switch is carried out in order to show usefulness of application for specific problems in the layered manufacturing process in order to get better final part. The results obtained from a case. study are implemented through 3D Print Technology.

Abstract: The surface roughness of the end product is a very important indicator of laser cutting quality.

The paper reports a comparison of surface roughness during CO2 laser cutting of tungsten alloy plate using

oxygen as assist gas, based on control charts made by statistical process control (SPC) approach.

Dependent variable is surface roughness, while independent variables are laser power and cutting speed.

The control chart used within this paper is a variation of the i-chart of experimental data samples, where

using evaluation of moving range of the two consecutive values, in order to estimate value of standard

error by average moving range and Hartley's constant d2. Applying the criteria often used in the SPC

methods for the assessment of "out of control" situations, it may be inferred that the observed differences

in surface roughness during CO2 laser cutting could be used to advice on the more appropriate laser power

and cutting speed for the laser cutting quality.

Abstract: The cut quality is of great importance during the laser cutting process. The quality of laser cut

mainly depends on an appropriate selection of process parameters. In this paper, the effect of process

parameters was analysed on the laser cut quality of an uncommon alloy, the tungsten alloy (W ≈ 92.5 %

and the remainder Fe and Ni) sheet with thickness of 1 mm. This alloy has a wide application in different

industrial areas, e.g. in medical applications, the automobile sectors, and the aircraft industry. This paper

introduces a developed back-propagation artificial neural network (BP- ANN) model for the analysis and

prediction of cut quality during the CO2 laser cutting process. In the presented study, three input process

parameters were considered such as laser power, cutting speed and assist gas type, and two output

parameters such as kerf width and average surface roughness. Amongst the 42 experimental results, 34

data sets were chosen for training the network, whilst the remaining 8 results were used as test data. The

average prediction error was found to be 5.5 % for kerf width and 9.5 % for surface roughness. The results

of the predicted kerf width and surface roughness by the BP-ANN model were compared with experimental

data. Based on the results of the study, it was shown that the proposed artificial neural network model

could be a useful tool for analysing and predicting surface roughness and kerf width during CO2 laser

cutting processes.

Abstract: This paper defines mathematical models of value changes for surface roughness (Ra, μm) and heat affected zone width (HAZ, mm) during high-alloyed steel 1.4828 laser cutting using oxygen as an assistance gas. For the definition of appropriate mathematical models, multiple linear regression analysis is used, with four independent variables that were varied at five levels. Following parameters are varied: cutting speed (V), assist gas pressure (p), focus position (fs) and stand-off (Nd). In comparison between the model and the experimental results, it can be concluded that the effects of specified parameters on cut quality, productivity and thus the legitimacy of this technology for cutting high-alloyed steels are well described by the obtained mathematical models.

Abstract: In the present paper, the effects of material thickness, traverse speed and abrasive mass flow rate during abrasive water jet cuttingof aluminum on surface roughness were in vestigated. GMT garnet was used as abrasive material with 80 mesh. Surface roughness was measured across of depth of cut. The experimental results show that traverse speed has great effect on the surface roughness at the bottom of the cut. It was also discussed the correlation between the surface roughness and other abrasive water jet cutting variables. Based on the experiments, the optimal process parameters for each material thickness were defined.

Abstract. The main objective of this paper is to find the optimal suture with comparative display of two

most used types of sutures that achieve the highest degree of security in sewing tendons, all in the aim of

quickly restoring the function of damaged tendon. The study was conducted on animal tendons, which

have all the necessary characteristics that are most similar to humans. For the comparison two types of

core sutures were selected in the study. The first one that was researched was modified Kessler core

suture with fascia which is routinely used at the Clinic for Reconstructive and Plastic Surgery, Clinical

Center of the University of Sarajevo. The other core suture that was selected was cruciate suture with

fascia or McLarney suture. For the purpose of statistical analysis of the measured data the test of variance

analysis (ANOVA) was used, with prior testing of the variables normality using the Shapiro-Wilk test and

Kolmogorov-Smirnov test. Based on the experimental results, it is evident that the variables that were

tested are in favor of greater reliability of cruciate suture with epitendinous fascia, which, in the tested

sample, compared to the modified Kessler with epitendinous fascia, puts it on first place and makes our

"ideal" core suture of flexor tendon.

Abstract: This paper defines mathematical models during laser cutting that describe effects of certain processing regime parameters on values for surface roughness - Ra and for width of heat affected zone - HAZ. Cutting of high-alloyed steel 1.4864 (X13CrNiSi35-16), with thickness of s = 3 mm and 1.4541 (X6CrNiTi18-10), with thickness of s = 4 mm was performed by laser cutting using O2 and N2 as the assistance gas. For the definition of appropriate mathematical models, multiple linear regression analysis is used, with four independent variables that were varied at five levels. Following most influential cutting parameters were varied: cutting speed (V), assist gas pressure (p), focus position (fs) and stand-off (Nd). It is possible to sufficiently describe the effects of process parameters, with defined models in reliable way, on product product quality and also to determine the best parameters of laser cutting of investigated high-alloyed steels.

Abstract: A quality constructive solution can be considered one that ensures the proper functioning and

reliability of the product with the least possible cost. Therefore, it is the main goal of every designer to

obtain the required girder capacity with minimal material expense in the cross section design of a full plate

10

girder. This ensures an optimal material participation in the overall price of the finished structure already in

the initial stage of design. This paper presents the I-profile shape cross-section optimization at the

overhead crane main girder, where the metal sheets stability calculation to buckling is made according to

BAS/JUS U.E.7.121/1986. The mathematical model is solved using the nonlinear programming method

SUMT (sequential unconstrained minimization technique) where from the goal function with constraints,

with introduction of the penalty function, a new function without constraints is formed and the function

minimum is sought.

Abstract: The abrasive water jet (AWJ) cutting technique is one of the most rapidly improving technological methods of cutting materials. In this paper a mathematical model for analysis and prediction of surface roughness during AWJ cutting of aluminium plate is developed based on experimental observations. Dependent variable in the model is average surface roughness, while independent variables are depth of cut in cutting process, traverse speed and abrasive mass flow rate. To evaluate results, analysis of variance (ANOVA) method is performed. Obtained regression model results suggest that regression modelling can be useful tool for analysing surface roughness in abrasive water jet cutting process.

Abstract: Stainless steel and aluminum sheets are the high reflective metals, so it can be difficult to cut it by laser beam. This paper presents optimization of cut quality during CO2 laser cutting of austenitic stainless steel and aluminum sheets. In the present study, three input process parameters such as laser power, cutting speed and material type, and two output parameters such as kerf width and surface roughness are considered. The results indicates that the good cut quality during CO2 laser cutting of both examined materials can be achieved.

Abstract: CO2 laser cutting of low alloy steel sheets is considered and the effect of cutting speed and

material thickness on the kerf width and the surface roughness is examined. It is found that the surface

roughness decreases by increasing cutting speed while the kerf width changes slightly with increasing

cutting speed. Also the results show that the surface roughness and the kerf width increase by increasing

material thickness while the cutting speed decreases by increasing material thickness.
