Opis:
Correct and stable machining process requires an appropriate cutting tool. In most cases the tool can be selected by using special tool catalogs often available in online version. But in some cases there is a need to design unusual tools, for special treatment, which are not available in tool manufacturers’ catalogs. Proper tool design requires strength and geometric calculations. Moreover, in many cases specific technical documentation is required. By using Computer Aided Design of cutting tools this task can be carried out quickly and with high accuracy. Cutting tool visualization in CAD programs gives a clear overview of the design process. Besides, these programs provide the ability to simulate real machining process. Nowadays, 3D modeling in CAD programs is a fundamental tool for engineers. Therefore, it is important to use them in the education process.

Opis:
Computer animation has a positive effect on memorizing knowledge by students. Used in the process of teaching of technical subjects, it is conductive to the development of mind. Animation allows to familiarize the students with the schemes of solving technical problems and shows the mode of operation of machinery and equipment. In the technique, animations are used, inter alia, in the processes of designing, engineering calculations, visualisation and monitoring technological processes and visualisation of assembly processes. The article discusses the role of computer animation in the teaching process and the examples of applications using computer animation and supporting the teaching process of technical subjects. Selected examples of technical processes in both computer-aided design and manufacturing programs as well as in graphics and animation programs are presented.

Opis:
Structural design analyses of industrial dye mixing machines, concerning mixing impeller geometries, mixing performances, and power requirements aren’t generally of scientific quality. Our aim is to propose a practical method for minimizing execution time, using parametric design. In this study, Visual Basic API codes are developed in order to model the impellers in SolidWork,sup>R software, and then flow analyses are conducted. Thus, velocity values and moment/torque values required for mixing operation are determined. This study is carried out for different shaft rotational speeds and different impeller diameters. Flow trajectories are obtained. After that, frequency analyses are conducted and natural frequency values are obtained. In the scope of this study, two different impeller types are investigated.

Opis:
Visualization models have accompanied the designing of buildings and structures since ancient times. Their purpose has been to give the investor an idea of what a building and different solutions applied in it would look like. To this end, models of different materials were built. But as technology progresses, it became possible to create new visualization tools and methods. Initially, drawing boards were replaced by computer programs referred to as computer-aided design (CAD), which supported the design process. They facilitated the creation of sets of lines and simple planes. With time, the designers increasingly felt the need to shape not just rectilinear but also curvilinear objects by means of computers. This is when parametrization came in handy. Parameters constitute a set of variables which can be shaped while keeping the interdependencies between them. Parametric modelling gave rise to the building information modelling (BIM). Now, a virtual model can not only be shaped in a digital environment but also enriched with different information. This way it not only has a geometry but also a structure. It was also assigned other data allowing identification of the material or technology used to erect a building or a structure. Parametrized elements of a building provide information about their number, purchase cost or physical properties. Parameters allow making quick and seamless corrections. Thanks to the application of advanced technologies, designers from different areas can keep track of these changes. Following accepting them, one can easily generate a complete set of technical documents and use them in a digital or paper format at a construction site. Parametrization makes it possible to erect buildings and structures that would have been impossible to design in the past. Today, every designer either already uses parametric modelling or will start using it sooner or later.

Opis:
The usage of noncircular gears makes possible to get better characteristics of the transmission. This problem is widely studied in the case of regular noncircularity, e.g., when a gear is of an elliptical or cycloidal shape. In this study, there are taken into account non-typical irregular gears. The design of such gears involves more advanced techniques, in particular there has to be applied a numerical treatment to get a mathematical description of the gear profile. In the paper, we discuss a parametric spline interpolation of the third degree and we give an example of such approximation. We also present a prototype drive making that the belt transmission has changeable kinematical features.
Zastosowanie nieokrągłych kół zębatych powala uzyskać lepsze charakterystyki przełożenia. Przypadki, gdy koła nieokrągłe mają kształty regularne, np. eliptyczny lub cykloidalny, zostały już szeroko przebadane. W tej pracy są poddane analizie nietypowe nieregularne koła zębate. Projektowanie takich kół wymaga bardziej zaawansowanych technik, w szczególności podejścia numerycznego w celu uzyskania matematycznego opisu profilu koła. W pracy omawiamy interpolację parametryczną za pomocą funkcji sklejanych stopnia trzeciego i stosujemy ją do uzyskania odpowiedniego opisu. Ponadto prezentujemy prototypowy napęd, w którym zostało zastosowane przedmiotowe nieregularne koło nieokrągłe. Zastosowanie tego koła w przekładni cięgnowej sprawia, że ma ona zmienne cechy kinematyczne.

Opis:
The paper deals with the problem of optimal configuration of a type of transfer lines which are equipped with transfer machines. Such machines perform operations with standard modular spindle heads which are activated sequentially. All operations assigned to the same spindle head (block of operations) are executed simultaneously by a set of tools fixed at the spindle head. The quantity of machines and spindle heads used to produce a part with the given productivity rate defines the final cost of the transfer line which must be minimized. To minimize this cost, a combinatorial problem of operations assignment to blocks and machines must be solved. The solution must provide a desired productivity (cycle time), it must also satisfy precedence and compatibility constraints. In this paper, we suggest improved versions of FSIC heuristic algorithm in order to help line designers to solve real-scale industrial problems. Results of computational experiments obtained for industrial cases are presented.

The article describes the development of fundamentals of machine elements and assemblies design processes automation using artificial intelligence, and descriptions of structural elements’ features in a natural language. In the proposed interactive automated design systems, computational artificial intelligence methods allow communication by speech and natural language, resulting in analyses of design engineer’s messages, analyses of constructions, encoding and assessments of constructions, CAD system controlling and visualizations. The system is equipped with several adaptive intelligent layers for human biometric identification, recognition of speech and handwriting, recognition of words, analyses and recognition of messages, enabling interpretation of messages, and assessments of human reactions. The article proposes a concept of intelligent processing for analysis of descriptions of machine elements’ structural features in a natural language. It also presents the developed methodology for similarity analysis between structural features of designed machine elements and corresponding antipatterns allowing normalization of parameters of the analysed structural solutions.

Opis:
Innovative exhaust system for light turboprop airplane has been developed and optimised. Apart from the basic function of removing exhaust from turboprop engine, the system supports cooling of the engine bay. To do this, the system removes hot air from the engine bay, utilising the ejector-pump effect, where the exhaust stream generates under-pressure, sucking the hot air through the ejector slot and removes the air together with the exhaust gases. The design and optimisation of the exhaust system has been conducted based on computational methods of Computer-Aided Design and Optimisation and Computational Fluid Dynamic. Three-dimensional analysis of flow around the airplane (including effect of propeller) and inside the exhaust system was conducted by application of URANS solver ANSYS FLUENT. Using these software the trajectories of exhaust particles, both inside the exhaust ducts and outside the airplane, have been determined. Parametric model of the designed exhaust system has been developed using the in-house software PARADES. As design parameters the diameter, length and direction of exhaust ducts as well as few parameters describing a shape of the ejector, have been established. The optimisation process aimed at designing of the exhaust system, which removes the exhaust gases possibly far away from the airframe, especially during a descent flight of the airplane. Additional objectives were maximisation of the mass flow rate of hot air sucked through the ejector and minimisation of the drag force generated by external part of the exhaust system. The optimised exhaust system should have also fulfilled requirements of permissible total-pressure losses inside the exhaust ducts. The optimised exhaust system has been implemented on the light turboprop airplane and validated during flight tests.

Programs CAD (Computer Aided Design) or computer support in the design, is the kind of software that is used for many years engineers building, architecture, and interior designers. CAD involves the use of computer technology in the design and preparation of documentation. CAD software can be used to design curves in two dimensions (2D) and the surface and three-dimensional objects (3D). Due to the enormous economic importance of CAD is the main driving force of research in computer geometry, computer graphics (both hardware and software) and in differential geometry.
Programy CAD (Computer Aided Design), czyli komputerowe wsparcie w projektowaniu, jest tym rodzajem oprogramowania, które od wielu lat służy inżynierom budownictwa, architektury, a także projektantom wnętrz. CAD polega na wykorzystaniu technologii komputerowych w procesie projektowania i przygotowywania dokumentacji. Oprogramowanie CAD może być używane do projektowania krzywych w dwóch wymiarach (2D) oraz powierzchni i obiektów trójwymiarowych (3D). Ze względu na ogromne znaczenie gospodarcze CAD jest główną siłą napędową badań w komputerowej geometrii, grafiki komputerowej (sprzętu i oprogramowania) oraz w geometrii różniczkowej.

Due to the rapid production of warp knitted jacquard spacer fabric in recent years, as well as physical properties of light, heat conduction, buffering effect, compression resistance, moisture permeability and air permeability, warp knitted spacer fabric has been used more and more widely in clothing, shoes and hats, as well as in fields such as medical care, construction engineering, safety protection and others. The design demand for different patterns and functions is also increasing gradually. Jacquard designers established a complete design model which plays a certain guiding role in the design of warp knitted spacer fabric. It brings innovative design to the surface pattern and structure of the fabric, making it more functional. The adoption of computer aided design also has a certain guiding role in the design process. Taking the CAD pattern design of warp knitted spacer fabric as an example, which combines the functional characteristics of the fabric and the jacquard pattern. Thus, we design fabric products that meet the market demand and initiate fashion trends.
