The article describes the development of a computerized system for measuring the weight of ore in the skip of a mine hoist. The purpose of this system is to provide operational information for the automated management system of the iron ore plant. The work includes the design of both hardware and software of the system. The hardware includes weight sensors that measure and transmit data to a central computing unit. The software includes data processing algorithms that analyze ore weight information and transmit the results to the control system. One of the key aspects of the article is the possibility of further refinement of the project and testing of the prototype system in the conditions of industrial production. This will make it possible to check the efficiency and reliability of the system in real working conditions, as well as to make the necessary adjustments and improvements before the end of the project. Summing up, the developed system has the potential to become an important element for optimizing and improving the efficiency of the iron ore plant, and also demonstrates the prospects of introducing similar technologies in other industries. The work highlights the potential benefits of using this computerized ore weight measurement system. Among these advantages can be noted an increase in the accuracy of measurements, a decrease in human intervention and, accordingly, an increase in the level of safety in production, as well as the possibility of prompt acquisition and analysis of data for management decision-making. In addition, the integration of this system into the management of an iron ore plant can help reduce material losses, optimize the use of resources and increase the overall efficiency of production. These aspects are important for the enterprise from the point of view of economic efficiency and stability in the market. Thus, the developed computerized system for measuring the weight of ore in the skip of a mine hoist is a promising and important step in the direction of improving technological processes in industry and increasing its competitiveness.

Turret lathes, which are automated turret machines, are widely used in large-scale and mass production. The use of automatic machines in small-scale production, which has a significant specific weight in instrument construction, was considered inadvisable until recently due to the fact that their reconfiguration takes a lot of time. Currently, thanks to the expansion of processing methods, which allow with minimal time consumption to go from the production of one part to the production of another part of the same group, automatic machines are increasingly used in small-scale production. The introduction of innovative methods to expand the technological capabilities of machines should go not only by increasing the accuracy of processing, a wider use of the expansion of functionality can be realized by equipping with auxiliary devices that can perform operations that improve the production of parts. One of the ways to improve the productivity of the automatic lathe is to use shaped cutters, which allow you to process the part faster and with better quality, and with the help of developing a methodology for calculating and adjusting the cams.

Experimental and computational methods of studying the stress state in the plastic region are characterized by various methods and accuracy of measurements, methods of mathematical processing of experimental information, and interpretation of results. The experimentally determined kinematics as a starting point is the most widely used method to study the stress-strain state in the plastic region. When studying the process of plastic deformation of porous blanks, the model of a rigid-plastic isotropic-strengthening porous body with a loading surface that has the shape of an ellipsoid with semi-axes. It depends on the amount of porosity and the ratio of the associated flow law as a mechanical model of the material. In the axisymmetric extrusion of porous blanks, the viscoplasticity method was used to determine the field of flow velocities based on the results of experimental studies. R-functions were applied to approximate experimentally obtained values. The problem of finding approximations was formulated in a variational statement. Cubic splines of one argument were used to interpolate functions. As a result, an approach was proposed, which consists of a particular sequence of calculating the derivatives of the coordinates of the nodes in time in combination with the R-functions approach. All the calculations were performed in Euler variables, eliminating the need to switch from Lagrangian variables and simplifying the solution. Additionally, this method allowed for working with an irregular and non-rectangular grid in areas with any shape of boundaries. This approach is more effective from the point of view of the approximation’s accuracy and the speed of calculations. Finally, the equation for calculating the porosity in the volume of the deformable workpiece based on the information about the distortion of the dividing grid elements was obtained. For stationary axisymmetric processes, a technique was developed that allowed for replacing the calculation of the accumulated deformation of the base material along the deformation trajectory by integration over the region. A technique was developed for determining the stress-strain state at unstable and stable stages of axisymmetric plastic deformation of porous blanks. The calculation results were compared based on the proposed experimental and calculation techniques and the finite element method.
