Purpose: The research aims to predict the parameters between the cutting speed range correlated to the depth of cut for the CNC lathe. Design/methodology/approach: The model predicts the cutting speed parameters carried out based on the data range between the depth of the cut and the cutting speed. That information has been derived from the machine tool handbook and expert engineer recommendations. The fuzzy logic-based methods were used to predict cutting speed parameters for three different materials: aluminium, machine steel, and stainless steel. The data range in each material was used to condition the membership function. Findings: The result shows that the prediction cutting speed parameters are related to the range of the depth of the cut between 0.15 and 0.4 mm. It is observed that if the depth of the cut is very high, the cutting speed is lower. The information obtained is slightly different from the machine tool handbook. It can be used with the feed rate parameters to perform the machining process of the CNC lathes in the smart factory. Research limitations/implications: Further research should focus on predicting surface roughness and tool wear in the turning. Practical implications: The cutting speed selection has a significant impact on manufacturing. It affects production time, tool wear, cost, etc. Generally, the parameter has been derived from machining handbooks or machine tools textbooks, and some data is vague because it has only maximum and minimum. The data between ranges is unclear for operation. Executing production planning for new engineers was hard, which can affect manufacturing systems. Therefore, proper and precise cutting parameters are required. Originality/value: General machine tool manuals often provide vague information on recommended parameters and only show the maximum and minimum values. In past research, it has only a determined parameters range for the experiment. The data between ranges is unclear for operation. In this research, the parameter prediction was performed between the cutting speed range related to the cutting depth, which is for use in the CNC lathe process.

Purpose: The paper presented here was intended to describe the extent to which secondary technical education in Poland is oriented towards the acquisition of qualifications needed in modern factories in line with the Industry 4.0 concept. Design/methodology/approach: The study was conducted by analysing information contained in the Ministry of Education and Science's classification of vocational education professions and in the core curriculum for vocational education professions. The professions analysed were those which, according to literature research, are the most desirable in an industry based on the concept of Industry 4.0. Information contained on the websites of selected schools was also analysed. Findings: As a result of the analysis carried out, it was found that the knowledge describing the qualifications of future technical staff in terms of Industry 4.0 is insufficient or even negligible. The core curricula do not require teachers in technical schools to address issues related to the concept of Industry 4.0. A lack of concepts related to Industry 4.0 in both the learning objectives and outcomes and professional qualifications was identified. Research limitations/implications: The research concerned only the professions taught in Poland in 5-year technical schools on the base of the primary school. Comparison of the studied aspects in other countries, e.g. the European Union, is difficult and requires more in-depth research. This is due to the diversity of systems of secondary technical education in individual countries and the non-uniform form of curricula. Practical implications: Several important conclusions emerge from the study. First and foremost, it should be emphasised that Polish schools do not prepare students studying in them for the phenomenon of dynamic development of manufacturing techniques represented by the idea of Industry 4.0. Graduates are not familiar with the assumptions, opportunities and threats related to it. Even if the substantive preparation of school graduates meets the requirements and expectations of Industry 4.0, schools do not promote this fact among potential candidates. Originality/value: The paper presents the state of qualification requirements in Polish secondary technical schools in the context of the development of manufacturing techniques associated with the concept of Industry 4.0. It answers the question of whether and to what extent curricula and professional qualifications contain requirements concerning knowledge of Industry 4.0? The results of the study may be an element in the discussion on the condition of Polish vocational education in the context of requirements for employees in modern factories.

Background: This paper has the aim to address the key area of managing complex Industry 4.0 production systems to support a successful adoption and integration of Industry 4.0. This is achieved by approaching methodological research challenges of Industry 4.0 in the form of lacking reference models and the need to establish common definitions of fundamental concepts. The general underlying challenge this paper aims to contribute to solve can therefore be defined as how the technological advances, like CPS, IoT, Big Data or CC can be best linked with each other on different levels of perspective and how they can be used by decision-makers to generate economic value and to improve existing processes. This is achieved through the introduction of the Industry 4.0 Knowledge & Technology Framework (IKTF). Methods: The Industry 4.0 Knowledge Framework (IKTF) is based on the concept of the micro-meso-macro analysis framework and consequently is representative for the approach of micro-meso-macro analysis in managerial practice. It proposes three categories of factors and places them in three basic levels layering them on top of each other. The macrolevel includes the financial, political and sociocultural factors that influence Industry 4.0. The meso-level includes the technical and organizational factors. The micro-level refers to individual factors, particularly individual companies’ intention to use Industry 4.0 in practical economic contexts. Results: The Industry 4.0 Knowledge & Technology Framework (IKTF) provides guidance to corporate decision makers by providing a comprehensive, multi-level sequential integration framework for Industry 4.0 based on a sequential micro, meso and macro perspective analysis of the individual corporate context. The aim of the IKTF is to support an informed and successful managerial decision-making process and therefore enable the integration of Industry 4.0 in a corporate context. Conclusion: As a first step, the structure, and contents of the IKTF are sequentially introduced and described. In a second and final step the functionality and applicability of the IKTF are demonstrated and discussed on a theoretical and practical level with the help of a case study.

In this article, it is described how the reconfigurable inter-operational buffers system built on the Digital Twin platform. Interoperating production buffers are now widely used in production. Their effect on the production system can be seen in decreasing downtime. From a cost-based point of view, the interoperating production buffers may generate a gain from the reduction in the volume of work-in-process, with which we increase production performance. This ratio depends on the average number of products that the buffers contain. The average number of pieces in the buffer is limited by the capacity of the buffer. The impact of turbulence in production is seen precisely on the average content of inter-operational production buffers. If we want to maintain work-in-process on optimal values, it is necessary to calculate and maintain the optimal capacity of each interoperating production buffer on the line. In the context of Smart Factory, it is currently possible that the current capacity of the interoperating production buffers is maintained according to the current state of production. In the subject system, real production facilities communicate with each other through the IoT as autonomous agents, which are decided on the basis of a formula to calculate the optimal capacity of the buffers, the prediction of faults and negotiation, thus actively maintaining the optimal capacity of intermediate operating production buffers for Smart Factory support.

Postępująca wirtualizacja gospodarki oraz rozwój mediów społecznościowych doprowadziły do zmian w środowisku pracy. W konsekwencji zmianie ulega model rozwoju kompetencji pracowników z centralnie zaplanowanego do zdecentralizowanego, charakteryzującego się samoorganizacją i dostosowanego do indywidualnych potrzeb jednostek. W artykule przedstawiono rozwój kompetencji pracowników w kontekście uczenia się na stanowisku pracy w warunkach nowej organizacji pracy i produkcji zwanej współkonfiguracją.

EN

The progressing virtualization as well as the development of social media changed the traditional workplace. Consequently, the model of employee competency development is changing from the traditional top-down “command and control” approach, towards more “decentralized” approach that is self-organized and addresses the individual needs of each employee. The paper presents the development of employee competences within the context of the workplace learning resulting from a new work and production called co-configuration.
