Manufacturing Technology 2023, 23(1):32-39 | DOI: 10.21062/mft.2023.004 
The article presents a comprehensive example that demonstrates the control of a plastic injection process in practice. It includes measurement and analysis of the production process, its control using a control diagram to bring the production process to a state under statistical control by applying tests of non-random clusters and subsequent evaluation of process capability. The last part of the article gives an example of the maintenance of economical statistical optimization for four scenarios.

Reusing the powder across consecutive route cycles is typical in a Selective Laser Melting (SLM) process since it is more sustainable and cost-effective. The theoretical part of the paper is oriented on the explanation of the SLM method principle, construction, and parameters of the device Renishaw AM250 used for manufacturing samples made of AlSi10Mg aluminium alloy. The experimental part focuses on evaluating powders that had been used in the process for a long time with periodic ‘rejuvenation’. The main aim will be to monitor whether the samples will be affected and if they achieved the required quality of mechanical properties and compare...
Studies on a Robotised Process for Forging Steel Synchronizer Rings in the Context of Forging Tool Life
Artur Meller, Marcin Suszyński, Stanisław Legutko, Marek Tr±czyński, Vit Cernohlavek

This paper proposes a solution not previously used in the forging industry, which aims to reduce the proportion of arduous human labour. The concept of a prototype robotic station for hot forging includes a system that allows the selection of batch material with its heating, the execution of the process of lu-brication of forging tools and the forging itself, synchronised with the feeding and removal of material using full automation, in accordance with the idea of Industry 4.0. At the same time, by increasing the repeatability of the entire forging process and changing some of its key parameters, it will be possible to influence the durability of...
Influence of Impurity Morphology on the Fatigue Strength of High-Purity Structural Steel Melted in an Electric Furnace
Tomasz Lipiński
Manufacturing Technology 2023, 23(1):53-59 | DOI: 10.21062/mft.2023.001
A modern user requires low operating costs, but also reliability from machines and technical devices. Reliability during the service life depends on the quality of construction solutions, but also largely on the quality, properties and adaptation to the working conditions used in the construction of construction materials. During the operation of technical objects, their a highly predictable wear occurs. The problem is the phenomena of premature wear and damage of elements. The causes of failure of technical facilities are usually complex and depend on many factors. They can include the human factor and the one related to the quality, selection, production...
