Radosław Auriga, Piotr Borysiuk, Michał Jezierski
The study examined the susceptibility to drilling of chipboards made of hemp shives. The research included measuring the axial force and torque when drilling chipboards with different hemp content (0, 25, 50, 75, 100%). Two variants of cutting parameters were used in the tests (6000 rpm and feed per revolution 0.2 mm and 6000 rpm and feed per revolution 0.25 mm). The results indicated that the share of hemp shives affects the value of the axial force and torque during drilling. However, an increase in the feed per revolution causes a significant increase in the axial force, but does not cause in a statistically significant effect in torque.so noted to have the best adhesion to narrow surfaces of particleboard when using EVA hot melt adhesive.
Characteristics of Industry 4.0 solutions used in the Polish furniture industry on example of the Nowy Styl Office Furniture Factory in Jasło
Lukasz Adamik, Jacek Wilkowski
The article presents a historical outline of the development of industry marked by a number of key technological changes, in subsequent versions called industrial revolutions. Industry 1.0, Industry 2.0 and Industry 3.0 were briefly characterized, indicating those discoveries and inventions that had a decisive impact on the production process and the dynamic development of enterprises. Most space was devoted to the idea of Industry 4.0 and its practical implementation in the Nowy Styl Office Furniture Factory in Jasło. The applied solutions related to the broadly understood integration of machines and IT systems, product personalization, practical implementation of short production series as part of flexible furniture production, while maintaining high productivity, short production cycle and the highest quality of the final product were characterized in detail.
Statistical analysis of the production batch size in the context of Industry 4.0 on example of the Nowy Styl Office Furniture Factory in Jasło
Jacek Wilkowski, Lukasz Adamik
The quantity of products of a specific type or design intended for production constitutes a production batch. In mass production, characterized by a small assortment, large production batch size occur, which reduces the unit costs of product production and increases the company's competitive advantage. However, the modern economy increasingly poses new challenges for factories. The production batch size is often significantly reduced. It is produced in short series, to individual customer orders, which are to be unique and tailored to the requirements and needs of retail customers. This is a feature that characterizes flexible production, which is a determinant of Industry 4.0. The article statistically analyzed the production batch size of plate furniture elements produced in the Nowy Styl Office Furniture Factory in Jasło, a representative of one of the few implementations of Industry 4.0 in the furniture industry in Poland. Descriptive statistics and histograms of batch size distributions were determined based on production data. The results obtained indicate very high production flexibility. The use of the central limit theorem (CLT) was proposed to assess the average size of production batch and the confidence interval of the estimated variable.
