Opis:: Introduction: This paper describes the results of research aimed at developing a method of otolaryngological diagnosis based on computational fluid dynamics, which has been called Virtual Rhinomanometry. Material and methods: Laboratory studies of airflows through a 3D printed model of nasal cavities based on computed tomography image analysis have been performed. The CFD results have been compared with those of an examination of airflow through nasal cavities (rhinomanometry) of a group of 25 patients. Results: The possibilities of simplifying model geometry for CFD calculations have been described, the impact of CT image segmentation on geometric model accuracy and CFD simulation errors have been analysed, and recommendations for future research have been described. Conclusions: The measurement uncertainty of the nasal cavities’ walls has a significant impact on CFD simulations. The CFD simulations better approximate RMM results of patients after anemization, as the influence of the nasal mucosa on airflow is then reduced. A minor change in the geometry of the nasal cavities (within the range of reconstruction errors by CT image segmentation) has a major impact on the results of CFD simulations.

Opis:: During design of the envelope of a noncircular belt pulley one should take into account several conditions resulting from kinematics and geometry of the uneven-running strand transmission. Design of proper values of pitches for a belt pulley, which enable good cooperation between the belt pulley and the belt, should be carefully done. In available Polish literature and catalogues offered by belt manufacturers, one can find only detailed dimensions of belts with a trapezoidal profile. Information on other profiles is insufficient for full description of geometrical features of belt pulley teeth as well as to design tools for machining belt pulleys. Manufacturers of belt pulleys and belts give only necessary data to submit a purchase order. The paper presents a digitization process (scanning) of geometry of the envelope of circular belt pulleys with non-standard profiles; this scanning has been done with the application of coordinate measuring machines. The obtained information on geometrical features of tooth profiles has been numerically analysed. As a result of this analysis, the mathematical description has been obtained. Finally, noncircular belt pulleys with different tooth profiles have been designed and manufactured.

Opis:: One of the processes of wet area is the separation of soybean’s skin using water as its media, with the cycle time is 45.59 minutes. The object of this research is the wet area on Tempe production in Indonesian Tempe House (ITH) at Bogor City to reducing the cycle time by designing soybean peel separator machine. This research was conducted using the reverse engineering method by performing an in-depth analysis of the tools used and developing the existing peel separator equipment based on user needs. Concept screening and concept scoring are done to select one of the best concepts of 48 possible concepts. The result of the selected concept of the soybean peel separator is the need for a propulsion motor as a replacement energy source for the operator's power and the mechanisms for separating skin and soybeans using water force from the bottom of the container. After that, the concept will be done by make a prototype and testing it in Rumah Tempe Indonesia with the result of cycle time is 70.77 minutes for all processes in a wet area, which means the cycle time is decreasing 39%.

Opis:: The paper presents design and manufacturing process of an individualized ankle orthosis using additive manufacturing technologies and reverse engineering. Conventional processes of manufacturing of orthoses are expensive and time consuming Thus, an alternative method was proposed. The patient’s leg was 3D scanned and the orthosis was designed using a CAD system. It was then manufactured using the Fused Deposition Modelling technology, assembled and fully tested. Positive results were obtained.

Opis:: Three-dimensional scanners are increasingly used in various fields of science (eg. medicine, computer graphics, architecture) and industry. There are a huge variety of methods to scan objects and their selection depends primarily on the type of the object and its location. Commonly used methods include branch laser triangulation methods. The objectives of this study is to provide a method for laser triangulation. It was described in the measurement system. In particular, this work examines triangulation methods based solely on the measurement system of the rotary motion of the object. The result of this measurement is a cloud of points is described in a Cartesian coordinate system. The work will be characterized examples of mathematical models of laser triangulation scanners.

Opis:: The modern design process is based on multi-criteria optimization methods. They require at the initial stage collecting a maximum amount of reliable information. In the case of centrifugal compressor would be desirable to obtain specified performance maps in the form of a digital array. High-resolution arrays are suitable to interpolate values between their nodes. Access to digital resources is often limited, because they are an intellectual property of the certain companies. As a temporary replacement is possible, the use of the characteristics published as illustrative or design characteristics published from solutions of the previous generations. Presented article takes the issue of adapting simplified compressor characteristics to the requirements of PMDO (preliminary multidisciplinary optimization) process. Selected characteristics due to the low density of the contour lines on the map field was not suitable for direct conversion into digital form Presented map was reconstructed by the method of approximation using a polynomials of nth degree. Reverse engineered map generates correct values at compressor contour map nodes. Chosen method is characterized by low demands in terms of computational power requirements, which makes it suitable to use also in embedded microprocessor control systems. Main advantage of presented method is allowed to create a working replacement of digital map that can be used until time when inputs will be complemented by experimental data.

Opis:: The necessity for quick responding to changing market conditions forces manufacturers to seek new ways of designing and implementing production facilities. One method manufacturers are quickly adopting is process modeling and simulation, often referred to as virtual manufacturing (VR). Virtual manufacturing allows engineers to view a computer-simulated version of how the final machines or processes should operate. They can eliminate process design flaws in the early stages of development, giving significant savings. The paper describes two examples of complex approach to solve typical engineering problems using advanced CAx system.
