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:: 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:: Technological and polytechnic education in the field of computer aided design (drafting) in 2D and 3D at non-technical secondary schools represents a new and relatively unexplored area. It is therefore necessary to deal with questions concerning the necessity of such training, and its potential influence and/or impact on students` further development. The answers were sought via an investigative research, the outcomes of which are presented by the submitted paper.

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.

Tytuł:: A grammar-based multiagent system in dynamic design
Autorzy:: Ślusarczyk, Grażyna
Opis:: This paper deals with the system of agents treated as a concurrent modular system, which is able to support the designer in solving complex design tasks. The behavior of design agents is modeled by sets of grammar rules. Each agent manages a graph grammar and a database of facts concerning the subtask for which it is responsible. The course of designing is determined by the interaction between cooperating specialized agents. The design context is expressed by the environment in which agents act and predicates describing design criteria. The organization, design methodology, and a semantic model of a grammar-based multiagent design system are presented. The notions of a valid design solution and a design solution consistent with the design criteria are also introduced. The proposed approach is illustrated by the example of designing a house estate.

Opis:: 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.

Opis:: 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.
