In the era of Industry 4.0, the digitization of production processes is one of the important elements contributing to the reduction of uncertainty related to the implementation of new production methods. The worldwide epidemic situation and its constraints have resulted in supply chain continuity problems. These problems make enterprises look for the possibility of producing products that they need at the moment and which they cannot obtain from the market. In special cases, this may also apply to spare parts necessary to maintain the continuity of production. The main reason for research on comparing production processes is meeting the challenges related to the pandemic situation and problems in maintaining timeliness, flexibility, and continuity of the supply chain. The first stage of the research was to visualize the course of the process and determine the lead times for both production methods. For further analysis, a digital process model was used to compare the hybrid and the classical method to check the viability of the interchangeability of methods for the production process of the flange part. The interchangeability of production methods was dictated by problems related to the supply of components for the execution of orders. The article simulates the model for unit and small-lot production in batches of 10 and 100 pieces, considering such aspects as: order completion time, energy consumption of the process, production costs, taking into account the classic and hybrid methods. The conducted research was aimed at determining the profitability of the production of flange-type products by means of classical processing and hybrid and checking the interchangeability of production methods in accordance with quality requirements as well as reducing uncertainty with the implementation of new production systems in changing market conditions. The simulations show that the use of hybrid production is recommended for unit production. In the case of small-lot production, already with 10 items, production in the traditional process is 21% cheaper, and for the production of 100 items, the cost of traditional production is reduced by 33% compared to hybrid production.

Digital processing of recorded measurement data on the milled surface can offer operators many possibilities in the planning metrological procedures processes and give more leeway in the final configuration of the surface geometrical structure condition. Review of the current state of knowledge revolving around surface characteristics, measurement uncertainty and their quality, and primarily reproducibility of measurements not only in the laboratory but also in the industrial environment poses a major challenge. The article presents research works related to the identification of the influence of the measurement data processing method using digital data processing of milled surface on the Sq parameter. The analysis of individual stages of measurement data processing showed the direct influence of data filtration methods on the values of the Sq parameter.

Cyfrowe przetwarzanie danych pomiarowych zarejestrowanych na powierzchniach frezowanych zwiększa swobodę w planowaniu procedur metrologicznych i końcowej ocenie stanu struktury geometrycznej powierzchni (SGP). Zagadnienia te nie zostały do tej pory znormalizowane. W dostępnej literaturze brak jest usystematyzowanego podejścia do problemów wyznaczania niepewności pomiarowych, a zwłaszcza odtwarzalności pomiarów. Problem ten dotyczy zarówno pomiarów prowadzonych laboratoryjnie, jak i w warunkach przemysłowych. W artykule przedstawiono wyniki prac badawczych związanych z identyfikacją wpływu cyfrowego przetwarzania danych pomiarowych, uzyskanych dla powierzchni frezowanej, na parametr Sq. Analiza poszczególnych etapów przetwarzania danych pomiarowych wykazała bezpośredni wpływ sposobu ich filtracji na wartości Sq.

Technological changes have gained strategic importance in the thinking and actions of many market players, penetrating at the same time into all links of the value chain and the ways of their connections, which changed the range of competition and the way in which the needs of buyers are met. With the development of industry 4.0 there is a need to create new business models. Building a good business model is a challenge because it requires taking into account the new conditions and resources of the company. The model iAn integral element in training of personnel in the Lean Manufacturing concept is the search for attractive forms of education which, in addition to the transmission of knowledge about a given instrument/method, will also be characterised by a wealth of practical knowledge. The use of simulation games is unquestionably an approach that allows to obtain a wide spectrum of practical knowledge in conjunction with increasing the effectiveness of conducted training/workshops. The article presents the theoretical basis describing both the essence and the advantages of the use of simulation games in conducting training for the personnel (both lower and upper level). The main objective of this article is to present the simulation game prepared by the authors - the simulation of “The Installation of the House”. As a co-operative game, it engages all the participants in active searching for losses and their origins in the process, and in looking for methods and techniques of eliminating wastage. This game has been developed for educational purposes, as a support for the teaching and training of personnel (employees of all levels of management). This simulation game, however, can be implemented in the training of production workers in the various companies, in order to ensure better understanding the methods of searching for wastage in the production process.

Problems on the world market, related to delays in supply chains, have forced enterprises to adopt a more flexible approach in the production processes of the offered products. In order to meet customer needs, companies can often look for alternative supply chains, as well as take over the production of key components necessary to maintain business continuity. Therefore, companies have to make important decisions in the context of management. A simulation model may be a tool helpful in making decisions related to production planning, which, based on the actual data collected from the process, allows for the verification of decisions before entering them into the real system. The motivation to conduct the research was the search for answers: How entrepreneurs, while maintaining profitability, can ensure the continuity of production processes by searching for alternative production methods. The article considers a comparison of two production processes for the production of a shield type product: classic production - on a lathe and hybrid production using the SLM method and machining only technologically significant surfaces on a lathe. The main goal of the research is to compare two production processes: classic and hybrid in terms of efficiency, energy efficiency and production costs. The research takes into account the use of different laser powers and the possibility of incremental production of several products at the same time. In order to achieve the assumed goal, a simulation model was used to carry out the research, which was developed on the basis of preliminary experimental studies. A series of simulations were performed, taking into account the variability criteria, and then the efficiency, energy efficiency and profitability of using alternative production methods were analysed.

In world literature much attention is devoted not only to the conscious surface shaping, but also to many problems that can be encountered during surface measurement. The development of surface metrology tries to respond to many industrial needs and keep up with sophisticated production techniques. Nevertheless the estimation and comparison of surfaces after several successive treatments is still complicated. For this purpose, the authors proposed the use of a correlation function to evaluate milled and then burnished surfaces, which is an alternative instrument to the parametric evaluation of the surface topography. This method can directly give an answer, whether the technological process has been carried out as expected. The measurements were carried out using a multi-sensor AltiSurf A520 instrument, manufactured by Altimet, according to its own developed methodology.

W literaturze światowej wiele uwagi poświęca się nie tylko świadomemu kształtowaniu powierzchni, lecz także licznym problemom, jakie można napotkać przy jej pomiarach. Choć rozwój metrologii powierzchni niezaprzeczalnie stara się odpowiadać na potrzeby środowiska przemysłowego i nadążać za coraz bardziej wyrafinowanymi technikami produkcyjnymi, to oszacowanie i porównanie powierzchni po kilku następujących po sobie zabiegach wciąż wydaje się skomplikowane. Właśnie dlatego autorzy zaproponowali wykorzystanie funkcji korelacji do oceny chropowatości 3D powierzchni frezowanych, a następnie nagniatanych, która może stanowić doskonałe uzupełnienie oceny parametrycznej. Funkcja korelacji wzajemnej może w sposób bezpośredni dać odpowiedź, czy proces technologiczny został przeprowadzony zgodnie z oczekiwaniami i wymaganym stanem chropowatości 3D. Pomiary przeprowadzono za pomocą wieloczujnikowego instrumentu AltiSurf A520, wyprodukowanego przez firmę Altimet, według własnej metodologii.
