    Opis:
    The paper presents a two-dimensional FEM model of burr formation in metal cutting. Abaqus/Explicit software was used for the build of the model. The workpiece geometry, the tool and the cutting parameters were modelled. Physical properties and the method of deformation and fracture of the workpiece material is described using Johnson Cook's constitutive law and the ductile damage criterion. The simulation of the edge formation process during orthogonal cutting was carried out for different depths of cut and cutting speeds. The results of these simulations allowed the verification of the FEM model. The components of the resultant cutting force measured during the actual cutting process with the values of these forces determined based on FEM simulation of this process were compared. The geometry of burrs formed during the actual and simulated the edge forming process was assessed. The analysis showed that the FEM model built enabled a correct prediction of the shape of the workpiece edge and the estimation of geometric features of the edge.

    Opis:
    In this work, an effort has been made to determine the effect of different shape surgical burr on the thermogenesis during bone osteotomy. The abrasion during bone grinding leads to heat generation and subsequently rise in the temperature which may have adverse effects such as osteonecrosis, blood coagulation in the carotid artery, damage to sciatic nerves, and even loss of vision. So, mitigating the temperature rise during bone grinding is of paramount importance. Especially, in endoscopic endonasal approach (EEA) in which nasal passage is used for the inserting the grinding burr and reaching the target region. The miniature abrasion can significantly increase the temperature and hence leads to the thermal damage to nerves surrounding the temporal and frontal lobe. These parts of the brain controls movement, problem solving ability, behavior, personality mood, hearing, language, memory, speech, breathing, heart rate, consciousness etc. Furthermore, neurosurgeons rely on their personal surgical experience for estimating the temperature rise during grinding. However, this is much difficult for novice surgeons. Therefore, it becomes critically important to preserve the soft neural tissues and nerves amid bone grinding. To overcome these concerns, infrared thermography technique has been exploited to determine the possibility of thermogenesis during bone grinding by measuring the temperature rise and its distribution using infrared camera. All experiments have been carried at a constant set of process variables. The grinding zone is continuously flooded with the irrigating solution to remove the heat and bone debris away from the grinding site. It has been observed that convex tool shape generated lower maximum temperature i.e. 46.03 ℃ among all tools. The temperature produced by the convex tool is 12.06% lower than spherical tool, 33.39% lower than cylindrical tool, and 10.55% lower than tree-shape tool. The results showed that convex shape tool could prevent thermal necrosis in the bone as temperature caused (i.e. 46 ℃) was less than the threshold limit of osteonecrosis. Thermograms revealed that infrared thermography technique could be implemented for the in-vivo surgical operations for the measurement of temperature during bone grinding.

    Opis:
    A model of burr formation on the edge of the workpiece in the course of machining is presented. The material being machined, the cutting tool and the machining parameters were modelled. Material properties and type of its deformations have been modelled with the use of a constitutive Johnson - Cook model. Material damage initiation criteria and associated damage evolution have been modelled with the use of the ductile damage and the Johnson- Cook damage initiation criterion. Simulations of the machining process for different depths of cut were carried out. The real burr formation presented by Hashimura was compared with the modelled one. The influence of the cutting parameters on the form and size of burr has been analysed. Calculations have been realised utilising finite element method with the use of nonlinear analysis in ABAQUS/Explicit environment. Based on simulation results, the assessment of the form and size of burr has been made. Burr height was used to evaluate its size, which was derived according to ISO 13715 standard. The goal was to obtain a model that reliably reflects the behaviour of material during machining, with particular emphasis on supporting the creation of cutting phenomenon of burr formation. The results of simulation and computational analysis confirmed that the model reflects the real behaviour of the material.

    The Burr X and inverse Gaussian (IG) distributions have been considered to design an attribute control chart for time truncated life test with the moving average (MA) scheme w. The presentation of the MA control chart has been estimated in terms of average run length (ARL) by using the Monte Carlo simulation. The ARL is determined for different values of sample sizes, MA statistics size, parameters’ values, and specified average run length. The performance of this new MA attribute control chart has been compared with the usual time truncated control chart for Burr X and IG distributions. The performance of a new control chart is better than that of the existing control chart.

    Opis:
    The stress-strength reliability (SSRe) model is widely investigated in reliability engineering to determine the probability of the strength component overcomes the stress imposed on it. In this paper, we studied the estimation of SSRemodel based on the Burr III distribution under the improved adaptive progressive type-II censoring scheme (IAPrgCS-II). Estimation methods of the SSReparameters are developed using frequentist and Bayesian approaches. The point and interval estimations using the maximum likelihood are considered to estimate the parameters. Two approximations are applied to compute the Bayes estimates. A simulation study is conducted for the comparison of the methods of estimation. Also, parallel to the development of reliability studies, it is necessary tostudy its application in different sciences such as engineering. Therefore, the droplet splashing (DrS) data under two wettabilities are proposed as an application of the considered SSRe model and methods. The results show us that the reliability model can be used to amend the quality of coatings.

    Opis:
    Drilling of rivet holes in stacked materials consisting of CFRP and Ti-6Al-4V still represents unique challenges. It is common practice to drill the material layers using one single tool. When exiting the final metallic layer, formation of a drill cap usually leads to undesirable burrs and debris, requiring manual post-processing. In this work, a drilling process to avoid drill caps is presented. This is realized using low frequency high amplitude vibration assisted drilling with defined coupling of the rotational speed and the axial oscillations. Drilling parameters and their impact on the quality of the drilled hole in the metallic layer are also investigated. It is found that drill tip geometries and process parameters need to be tuned together to achieve a stable and repeatable process for drill cap avoidance. A highly sensorized experimental setup with multi-sensor systems including high-speed and thermal imaging was used for process evaluation.

    Opis:
    Purpose: This research aims to analyse the influence of blanking clearance size on the burr development for mild steel sheet, brass and aluminium. The main reason for this research is estimating the burr size on blank parts. It is still significant since the quality of the products is determined by evaluating the amount of allowable burr in the parts. Design/methodology/approach: For the blanking process on the 3.00 mm thick sheets, various sizes of blanking clearance for a 20 mm diameter of the die opening are employed, as is the technique for obtaining the parts. Then the height of the burr on each product was measured using a micrometre and toolmaker microscope. The height of burr for each size of blanking clearance have been recorded and compared using a graph. Comparison made to identify which measure of blanking clearance and which type of material will produce a small size of burr. Findings: For mild steel, brass, and aluminium, blanking clearance 0.15 mm produced burr heights of 0.088 mm, 0.015 mm, and 0.024 mm, and blanking clearance 0.13 mm produced bur heights of 0.192 mm, 0.055 mm, and 0.046 mm, respectively. The brass had a lower burr height than mild steel and aluminium, according to the results. More significant blanking clearance (0.15 mm) produced a smaller size of burr compared to a smaller blanking clearance (0.13 mm). Practical implications: This study focuses on burr height rather than the wear of the punch and die cutting edge; burr height can affect punch and die sharpness. It also can guide practitioners in estimating blanking clearance and the burr height of mild steel, brass and aluminium. Originality/value: This paper demonstrates that the gap between the punch and die influences the burr height. The material strength also affects the burr height, with a high tensile strength resulting in a larger burr.

    Opis:
    W artykule poruszono problem wykorzystania różnych sposobów raportowania w odniesieniu do szacowania ryzyka operacyjnego metodą LDA. Zaawansowane metody pomiaru w najnowszych rozwiązaniach Komitetu Bazylejskiego ds. Nadzoru Finansowego prawdopodobnie nie będą już służyły do określania wielkości kapitału regulacyjnego, jednak ich przydatność dalej może stanowić jeden z elementów systemu zarządzania ryzykiem w instytucji finansowej. Celem artykułu jest zbadanie wpływu utraty informacji o zdarzeniach operacyjnych na stabilność szacunków ryzyka metodą LDA. W tym kontekście proponowane w artykule rozwiązania wykorzystujące rozkłady lewostronnie cenzurowane mogą stanowić dodatkowy kierunek ich rozwoju. W artykule przedstawiono problem na przykładzie lewostronnie cenzurowanego rozkładu Burra typu III, który może być podstawą do wyznaczenia rozkładu dotkliwości strat. Rozważana koncepcja polegająca na cenzurowaniu danych została porównana z powszechnie wykorzystywanym w praktyce rozwiązaniem polegającym na ich ucinaniu. Przeprowadzone badanie symulacyjne pokazało, że w przypadku cenzurowania danych można oczekiwać bardziej stabilnych wyników, które będą bliższe sytuacji pełnej wiedzy o zachodzących procesach, na podstawie których jest szacowane ryzyko operacyjne. Estymacja parametrów z zastosowaniem danych cenzurowanych wykorzystywana powszechnie w innych obszarach badawczych może być jednym z kierunków rozwoju również w przypadku ryzyka operacyjnego w instytucjach finansowych.
    The article is addressed to the problem of using various types of reporting in regard to estimating the operational risk with LDA method. Advanced Measurement Approach of estimation in the latest solutions of the Basel Committee on Banking Supervision will not probably be used anymore for defining the size of regulatory capital, however, its usefulness may remain one of elements of risk management system in financial institution. The aim of the article is to examine an impact of loss of information about operational losses on stability of risk estimates performed by LDA method. In that context, solutions which use left censored distributions that are proposed in the article, may be an interesting alternative in practical solutions. The article presents the problem of left censored Burr type III distribution, which may be foundation to determine severity of losses distribution. Considered concept that is basing on censored sample was compared to truncation which is very common solution in practice. Simulations has showed that in case of censoring of data we can expect more stable results which will be closer to situation of full knowledge about happening processes on which operational risk is basing. Estimation of parameters on the basis of censored data used commonly in other research areas may be one of directions of development also in case of operational risk in financial institutions.

    The exponentiated Burr Type XII (EBXII) distribution has wide applications in reliability and economic studies. In this article, the estimation of the probability density function and the cumulative distribution function of EBXII distribution is considered. We examine the maximum likelihood estimator, the uniformly minimum variance unbiased estimator, the least squares estimator, the weighted least squares estimator, the maximum product spacing estimator, the Cramér–von-Mises estimator, and the Anderson–Darling estimator. We derive analytical forms for the bias and mean square error. A simulation study is performed to investigate the consistency of the suggested methods of estimation. Data relating to the wind speed and service times of aircraft windshields are used with the studied methods. The simulation studies and real data applications have revealed that the maximum likelihood estimator performs more efficiently than its remaining counterparts.

    Opis:
    High-quality products include those with better surface quality and texture, close dimensional tolerances and form accuracies at precise level, increase fatigue life and burr-free. Burr formation is one of the most common inevitable facts occurring in all material removal processes, reduces assembly and machined part quality. But, burr formation during milling is a more complex mechanism compare to remaining machining burrs and leads to numerous difficulties during the deburring process. To prevent this, one should optimize the combination of cutting parameters during machining itself. In order to build up a link between quality and productivity and to attain the same in the cost-effective way, the present work concentrate on multi objective optimization of CNC end milling process parameters. Multiple performance characteristics with respect to surface quality and performance index like assembly work have been put up, to assess an equivalent single quality index (called grey relational grade) has been optimized finally by Grey based Taguchi method. After that priority weight of individual quality and performance attributes has been estimated by entropy measurement technique on the basis of relative significance and check the feasibility of the proposed technique has been demonstrated in this context.

    Opis:
    From ancient days to till today manufacturing industries, especially making of holes on the parts during drilling process for precision assembling of parts facing problems with burr formation. Drilling operation is one of the finishing operation in the production cycle, removing of burrs during drilling process is a time consuming and non-value added process to the manufacturing sector. So reducing the size of burrs is the main aim of the present study. In the present work, optimization of burr size is considered during drilling of aluminium 7075 alloy. In this connection, experiments are conducted based on Grey based Taguchi. From Grey relational grades of responses selected optimal combination of parameters to attain multiple performance characteristics of responses with a corresponding higher grey relational grade. For identifying the most significant input parameters that influence the output responses ANOVA is conducted. Based on interaction effect plots of data means of responses from results of ANOVA, confirmation tests are conducted by choosing most significant parameters. Finally, observations reveals that feed rate, point and clearance angles are the most influential factors on burr size and also experimental results divulge that the lower the thrust force causes to decrease the burr height. The proposed approach is helpful to the budding entrepreneurs in the related areas to select optimal combination of drilling parameters to attain multiple performance characteristics of responses especially in burr size to prevent the post finishing operations up to certain extent.

    Requirements for quality and the full traceability of products supplied in some industries, such as eg. the food industry, the pharmaceutical industry as well as automotive industry, result that the implementation of production flow control systems (FCS) becomes a very important element in the functioning of enterprises. Production flow control systems are used generally for recording production data at different stages of industrial processes (in this respect, they fulfill the function of traceability systems), but also provide blocking of incorrectly processed identifiable components during the earlier stages of the production. The information provided by traceability can be the basis for the functioning of integrated information systems. Production flow control systems ensure the recording of important information from the point of view of customer that allows the capture of defective products, analysis of the causes of these defects, and defense against potential complaint or even a significant reduction in the number of complaints. Applied are dedicated or universal solutions, adaptable to a variety of configuration lines / production cells. Dedicated solutions (for a specific production line) are basically always developed from scratch, taking into account the specificity of the product flow. Then the structure of the data in the PLC has to be adjusted, as well as the structure of the database and the database queries. Dedicated systems have the advantage that their action is fast, whereas the drawback is a longer start-up time and modification / expansion of functionality. On the other hand, universal solutions allow to configure the number of workstations and their type (controlled by a PLC or PC), their network addresses, as well as the types of products allowed there without changing the software. The advantage of universal solutions is that additional production workstations can be added very fast to the system, while the disadvantage may be longer lasting query the database and exchange information with the PLC. The concept of an universal system must be well thought and considered have to be different configuration cases of the material flow. Poorly thought-out concept takes revenge on the creator by the necessity of profound changes in the structure of the data and the application code. The purpose of this article is to present the advantages and disadvantages of dedicated and universal TCS / FCS systems.
