AB  - High demand for part customization shifts industries toward AM technologies. Part customization in high-volume manufacturing is developed to its limits, whereas low-volume production using AM is still economically unjustified. FDM technology is quite common in low-volume AM production, but the main issue is poor printing parameter optimization which may result in insufficient final part quality. The subject of this paper is the experimental determination of the optimal parameters for the PLA polymer FDM parts, focusing on nozzle temperature and printing speed. Part geometry and mechanical properties are evaluated for the temperature range of 170–210 °C and speeds of 40, 80, and 120 mm/min. Roughness measurements for part geometrical accuracy assessment and tensile tests for mechanical property estimation have shown the clear advantage of 190 °C and 40 mm/min over the other parameter combinations. However, for higher FDM process productivity 80 mm/min speed may also be considered with 190 °C.

AB  - The hypothesis that the part is homogeneous and isotropic simplifies the processing planning process. However, assumptions also have a negative impact on the processing result. Residual stresses within the material, which can affect the deformability of the part during and after the machining process, are directly reflected in the final dimensions and the desired geometry of the part. Experimental research was conducted on the material AlMgSi1 (6082), in order to establish a model for predicting the intensity of deformability of the work. The experiments were conducted on two different parts, obtained from the preparation of the same geometry and dimensions. In the first case, the part in the shape of a vessel was processed, from solid material, while in the second case, the bottom was removed. It turns out that when machining parts of greater height, without a bottom, from solid material, there is a significant probability that the work will twist. In the case when the bottom is retained, the intensity of deformations is also present, but in a much smaller percentage. Such knowledge is extremely important in proper production planning. In this way, significant savings in production time and cost can be achieved by adequately defining offsets for rough and fine machining, while obtaining a part that meets the defined accuracy according to the technical documentation.

AB  - Several years ago, research has begun in the field of free form surface machining at the Production engineering department at the Faculty of Mechanical Engineering in Belgrade. In this research, cases with ball end mill cutter machining were analysed, especially when it is possible to machine with maximal cutter diameter loaded from software database. On this way, it is possible to obtain an approximate shape of the free form surface faster than machining with ball end mill cutter. Using developed strategies for rough machining it is possible to reduce machining time and according to this reducing the cost of production and the cost of final product. In previously developed CAM application, new machining strategy was implemented and NC code was generated using that application. Experimental verification of generated NC code was performed on the CNC milling machine. After machining, measurement of produced part was performed and it was concluded that machining was performed in defined tolerances

AB  - Micro-cutting as a material processing process is completely different from classic macro cutting. Defining the mechanism of micro-cutting is one of the goals followed by the world's researchers. One of the most common approaches so far is the identification of micro-cutting with the static indentation of an indenter, which is the subject of this paper. In the case of micro-cutting of brittle materials, where the presence of its destruction during processing is pronounced, by static indentation it is possible to establish which types of cracks occur inside the material. Another important thing is that with this method it is also possible to define the critical penetration depth below which brittle materials can be processed by the mechanism of plastic deformation.

AB  - In this paper, an experimental examination/analyzing applicability and machinability of the polymer material’s core and cavity formed using additive technology (rapid tooling) was conducted. Achieving the price reduction of the final product, as well as the price of the mold for plastic injection through the introduction of rapid tooling injection molding can be applied, not only to mass production, but also to small series production. This research is limited to obtaining plane parts of simpler geometry from polypropylene polymer material. Obtained results showed that, at this point, it is not directly possible to completely produce a core and cavity only through additive technologies. In order to achieve some tolerances at specific places, it is still necessary that the core and cavities are machined with conventional methods. On the other hand, it turned out that by using a polymer core and cavity, it is possible to produce a smaller series of the parts.

Cutting force prediction is very imporlant to optimize machining parameters and monitor machining state. In order to predict cutting force of suiface machining with ball end mill, contact state between cutter and workpiece are studied. The resulting surface quality after machining with ball end cutter is of superior imporlance because finish milling is often the last process step determining the JUnctional performance of a component. In this paper is presented the state of the art in the field of force prediction in ball end milling and advantages of different methods for determining the cutter­ workpiece engagement.

AB  - This paper has presented the development of a sequel of conducted research in the field of free form surface machining at the Faculty of Mechanical Engineering in Belgrade. In order to machine as much as a possible material, it was developed machining strategy for rough machining with end mill cutter with a big diameter as the part of free form surface machining. Rough machining according to the developed strategy allows obtaining an approximate shape of the free form surface in the shortest possible machining time. After rough machining, one part isn’t present big deep of cut for finish machining with ball end mill cutter which is also the final step in machining. Using this strategy is possible to reduce the cost of production and according to that cost of the final product. The developed strategy was implemented in the CAM application and using it NC code was generated. Experimental verification of generated NC code was performed on horizontal working centre and measurement of a machined part was performed after machining too. With analysis of measured dimensions, it was verified usage of developed strategy which was implemented in CAM application.

AB  - In the field of mass production, injection molding accounts for a large percentage of the technologies used in the applied technologies. One of the main disadvantages when it comes to injection molding is the cost of tools. This can greatly affect the price of the finished product if there are multiple iterations of product development through various prototypes. For initial tools used in running production or in product design, it is necessary not only to be as cheap as possible, but also to make their production time as short as possible. The increasing application of additive technologies in the field of rapid tooling, gives a wide space in the possibility of lowering the price of the final product. The applicability of additive technologies in injection molding has not been sufficiently researched, although the possibility of application is huge. In this paper, the main emphasis is on the applicability of additive technologies in injection molding of an initial series or a smaller series of the parts. The conclusion is that not only additive technologies can be applied in the production of core and cavity or complex parts of injection molding tools, but the minimum time that is required to produce the tool is significantly reduced, which directly affects the price of the final product.

Experimental investigation of the tool radius and micro-cutting speed influence on micro-cutting mechanisms for marble based material

AB  - In this paper, a detailed experimental analysis of the effect of tool tip radius and cutting speed on the proposed mechanism of micro-cutting Plavi tok marble was performed. Although Plavi tok marble belongs to extremely brittle materials, experiments have shown that it can be processed in ductile mode (plastic deformation mode), i.e. without the presence of brittle fracturing of the material. Moreover, it has been established that the range of plastic deformation zone is a function of the tool tip radius and the cutting speed. The diamond tools used during the experiments had tip radius values of r = 0.15 and r = 0.2 mm, while cutting speeds were 15 and 25 m s(-1). When using tools with higher tip radius values, with increasing cutting speed, the critical penetration depth (ductile-brittle transition) increased from 8.8 to 9.3 mu m. On the other hand, tools with lower radius value led to a reduction of the plastic deformation zone range. This declining trend of plastic deformation zone continued during increased cutting speed, with critical penetration depths of 8.6 and 8.3 mu m for cutting speeds of 15 and 25 m s(-1), respectively. The intensity of lateral/radial destruction in the brittle fracturing mode was also directly dependent on the processing conditions. The reduction was achieved by using tools with a lower value of the tip radius while processing at lower speeds. In this paper, the identification of the components of the cutting force was carried out, whose intensities indicate the occurrence of the brittle destruction within the material.

Практична настава из предмета Алати за обликовање лима састоји се из
лабораторијских вежбања где се студенти упознају са практичним решењима
алата за обликовање лима, као и обрадним системима, и израдом пројекта алата
за обликовање конкретног изратка из праксе.
Практикумом су обухваћене припреме за израду пројектног задатка који се
односи на конструисање алата за обраду лима за задати израдак. После
обављених вежби, студенти су оспособљени да самосталним радом, уз
предвиђене консултације, пројектују алат за обликовање лима и генеришу
потребну излазну техничку документацију.
Практикум је конципиран кроз седам вежби. Прве четири вежбе уводе студенте
у начела моделирања делова од лима, а у петој врши се дефинисање положаја
дела на траци лима и дефинишу операције обраде. У последње две вежбе,
детаљно је описан поступак аутоматског пројектовања вишеоперацијских алата
са редним извођењем.
У вежбама су приказана упутства за коришћење софтвера PTC Creo Parametric 6.
уз модул за пројектовање технологије обраде лима и конструисање алата Creo

Rapid prototyping technology includes using of a digital information chain CAD/CAM/CNC to a level which allows the successful realization of the physical models based on new technologies by adding, subtracting and molding material. The paper discusses about the usual technologies for rapid prototyping, for which a generalized methodology for their application has been proposed. The possibilities for program verification prior to the realization of the model were also shown. The methodology is verified on real examples of making selected parts. Used technologies are subtracting and adding material layers, layer by layer, and mold making (by adding material) for molding the silicone model.

AB  - After noting that head and neck injuries are very common in martial arts sports, a growing need for developing helmet materials and models appeared. In addition to the problems that arise in terms of design, there are also problems in terms of developing the material from which the helmets are made. In terms of design, the helmet must interfere as little as possible with the mobility of the head and neck and visibility, while in terms of material development, it is necessary to ensure optimal mechanical properties of the material from which the helmet is made, which is simultaneously the biggest challenge for helmet manufacturers. In the process of developing models and materials of helmets, there was a need for research in which the development of experimental settings will credibly simulate the blows that are exchanged during a sports fight. The aim of this paper is to make an experimental setup to enable testing of helmets from different manufacturers as well as testing of newer generation helmets. This paper presents a conceptual solution of an experimental setup in which impacts are simulated in controlled conditions, taking into account that the impact image applied to the head model is controlled, so that it is possible to simulate different types of impacts while maintaining the same boundary conditions.

AB  - Developed procedures for tool path generation and application representing a CAD/CAM system is presented in this paper. This application allows automatic manufacturing technology design for parts with free form surfaces for loaded CAD models of part and work piece in STL file format. Generated tool path will represent optimal tool path in accordance with multi criteria optimization methods. Developed application allows usage without any user's expertise in the field of CAD/CAM systems. The optimal tool path for manufacturing will be generated, which will be performed in the shortest time possible, having appropriate surface precision and quality. Developed procedures which are implemented in this system are the result of years of research in this field at the Department of Production Engineering, Faculty of Mechanical Engineering, University of Belgrade, Serbia. Also, development of cutting force model and experimental determination of cutting force coefficients for tool/work piece geometry and material combination is described. Research was conducted for combination of aluminium work piece and ball end mill of HSSE steel. The application is developed as a GUI interface, in MATLAB software. Mentioned application allows generation of NC codes for rough and finish machining for the tools stored in the application database. According to the generated NC codes, several parts were manufactured using the horizontal working centre in order to verify developed procedures for tool path generation and optimization. Based on the conducted experiment, it was concluded that the machining was performed in allowed tolerances and cutting conditions which confirm the usability of the developed software application.

AB  - A new research was made in the field of free form surfaces machining at the Faculty of Mechanical Engineering in Belgrade, focused this time on rough machining of free form surfaces. This paper describes the development of this concept which is used when machining is not possible to be performed in one pass with ball end cutter. Based on a loaded CAD model of the workpiece and part, the developed system makes a machining simulation for ball end mill in one pass. In certain cases, when removing material in one pass is not possible, the system will provide two options for rough machining. The first option obtains an approximate shape of the free form surface for machining with end mill cutter in case the generated stock allowed parameter has an appropriate value for machining in one pass with a ball end cutter. The second option for rough machining with ball end mill performs two or more passes, maintaining the maximum allowed cut depth for the chosen tool in every single pass. After the final pass, the tool would be moved to next leading plane. The decision which option to choose out of these two depends heavily on the machining time generated by the machining simulation, which is supported by the developed system. By default, the system generates NC code for the strategy providing shortest possible machining time.

AB  - This work presents experimental study of the influence of layer thickness on surface quality and printing time using FFF/FFD method. Better surface quality of the printed part is achieved using thinner layers. Print time and achieved surface quality are in indirect correlation, on what basis, in order to satisfy both goals, detailed study needs to be done. Implementation variable layer thickness along Z axes can led to significantly reduction of printing time, but in the same way maintaining desired surface quality of the printing part. By applying the variable thickness of the layers, mostly benefits were obtained in zones where is a large change in the geometry in the part between the layers, such as spherical, conical, curved, and other shapes of complex surfaces. Constant and variable layer thickness experiments were conducted with bio-based polymer PLA on benchmark specimens. Constant thickness of the layers was 0.1, 0.2 and 0.3 mm, while variable values of the layer’s thicknesses were form 0.1 up to 0.3 mm in steps of 0.04. Four specimens were produced on 3D printer with same printing speed of 60 mm/min, nozzle temperature of 205 °C and bed temperature 60 °C. After detailed microscopic study of the printed benchmark specimens, can be concluded that from the aspect of printing time and surface quality, optimal results can be expected when using variable layers thickness. In this way, good balance between printing time and surface quality is achieved.

One of the key reasons for this kind of experiment is that most widely used commercial 3D printers produce parts that have uneven quality along its geometry when using out of the box air deflector. Experiments were carried out on the Anycubic i3 3D printer using PLA filament that requires adequate air flow for proper curing of the part. During printing process, custom made air deflectors were used. In addition to the original air deflector, which is in the direction of one axis (+X), three other constructions of the deflector were used, which were previously printed on the printer itself. First air deflector direct air flow in two directions (+Y and -Y). Other two were ring-shaped made therefore directed air flow all around the printing zone with 12 and 30 holes equally distributed in a circle. The experiments were performed on the test part using identical values of print parameters in order to minimize additional factors that causes variability of the print quality (nozzle temperature = 200 ̊C, bed temperature = 60 ̊C, printing speed = 80 mm/s, layer height 0.2 mm). The experiments showed that best results can be achieved using a ring-shaped air deflector with 12 holes and with 100% air flow. This type of air deflector is recommended to use in further works, instead of out of the box air deflector.

AB  - Defining how the chip is formed during micro-cutting can be extremely difficult. The reason is the miniaturization of the process itself in relation to the macro cutting, as well as, the smaller depth of cut in relation to the tool tip radius. Besides, the micro-cutting mechanism is influenced also by the material being machined, as well as the processing conditions. Considering that marble is brittle by its nature, the micro-cutting mechanism does not match that defined for various types of steel, aluminum, etc. Experimental analysis revealed that during the micro-cutting of marble, two different processing modes occur. In the first (ductile mode) micro-cutting is based only on the elastic and plastic deformations. In the second, which corresponds to the brittle fracturing mode, the chip is created by the formation and uncontrolled growth of the cracks within the material. The critical depth of cut that separates the two modes can be determined in many ways, and one of them is the static indentation. In addition, this method can also be used to identify the types of cracks that occur during micro-cutting in a brittle fracturing mode, which is done in this paper.
