“…1) and contain about 75% aluminum oxide (Al2O3), which is the main phase. The remaining components are represented in different combinations of refractory metal carbides (TiС, WC, MoC) [1,12]. The main factors affecting the cutting properties of ceramic cutting inserts are the microstructural parameters of the material, which include the number, distribution pattern and size of carbide inclusions.…”

The article deals with the determination of the efficiency of a multi-bladed tool equipped with inserts made of oxide-carbide cutting ceramics, depending on the microstructural parameters of the tool material. The microstructural parameters of the oxide-carbide cutting ceramic, which affect the performance of the tool, are proposed to be determined according to the electrical resistance of the tool material. In order to implement the method for determining the working capacity of the instrument, a basic design of the device for measuring the electrical resistance of the material of the instrument is proposed. The device for measuring the electrical resistance of ceramic plates consists of a body made of a dielectric material, with channels for supplying a conductive material and a groove for installing a case with a test sample. During the test, the channels are filled with a liquid conductive material, which fills the cavity formed by the channel of the case, the groove of the case and the plate itself under test. To ensure uniform filling of the cavity, after the introduction of the liquid conductive material, metal balls are installed into the channels, which are made in such a size as to ensure free sliding along the channel, but not to let the liquid pass into the upper part of the channel. The tested ceramic plate is installed in the walls of the removable case. The walls of the removable case include electrodes, which, when the device is in operation, are inserted into a cavity with a liquid conductive material at one end, and are connected to an ohmmeter at the other. Using a device for measuring the electrical resistance of ceramic plates, it is possible to determine the operability of the tool and guarantee its operation without rejection for a certain period of time, which was confirmed by experimental research in the milling of workpieces of machine parts made of gray cast iron. Experimental studies in multi-edge machining with cutters with different values of electrical resistance of ceramic plates made it possible to plot graphs of the dependence of the quality of machining during milling on the operability of the tool and on the time of the machining process.

“…The production processes description in the production and logistics system of mass production has a high level of detail. Production and logistics systems of mass production are a traditional object of simulation modelling [45][46][47]. Thus, we can distinguish two main types of machine-building enterprises for which it is advisable to use two types of simulation modeling: serial and mass.…”

“…Several tests of the automatic generation of augmented reality generated product assembly workflows have been performed, showing that it is possible, albeit with technological limitations, to machine-generate an augmented reality instruction manual [45]. However, in the sources studied, no dependency was found between the use of advanced visualization tools in the context of technical production preparation and the nature of the production processes [46,47] (there are only partial studies that are limited to limited aspects, namely under laboratory conditions, e.g., [48]). This is because manufacturing processes have many parameters (e.g., [49]) that could have a major influence on whether it is appropriate to use modern tools for a particular manufacturing process, or which tool is more suitable for a given process [50].…”

This article deals with the rationalization of manufacturing processes within the product life cycle with emphasis on the pre-production phase of production. A new methodology for evaluating the applicability of modern visualization tools in manufacturing processes is presented. This methodology includes a modified Z-score for categorizing manufacturing processes and has been validated by the successful implementation of 10 real projects. Ultimately, the methodology provides a practical decision-making aid for manufacturing companies in deploying such Computer Aided Instruction tools. For the pre-production phase of products and their development, the possibilities of using modern visualization tools to support CAD instructions and assembly instructions are being explored. These modern visualization tools are video tutorials, augmented reality tutorials and virtual reality tutorials. This paper explores the use of these tools for rationalization of pre-production processes. A methodology was designed to select the most appropriate tool for rationalizing process execution in preparation for production. The functionality of the methodology was verified by applying the methodology in industrial practice and subsequent implementation of the recommended solutions. The methodology was validated by testing key combinations that can arise based on the methodology directly in the operations of manufacturing companies. A total of 10 implementations in real production processes were tailored to this study and carried out over 2 years and the functionality of the methodology was confirmed (that consisted also of a new software development). It was found that there is a dependency between the visualization tools chosen to create the instructions in the context of organizational production preparation and the nature of the production processes.
