. Problem Statement (Relevance). Alluvial gold deposits mainly have a complex structure with a significant variability in the content of the useful component and the size of gold grains in sands of the producing formation, and, therefore, their development, using conventional processing technologies focused predominantly on gold recovered by gravity with a size of over 0.5 mm, leads to large losses of gold. The known technologies for the development of deep-seated placers are not focused on the selective extraction of sands with different levels of gold content and size; therefore, they do not provide the possibility of flexible changes in process flow charts, modes and parameters of processing the mineral mass, which is not uniform in its quality. A necessary condition for the use of the selective extraction of sands and their separate processing is the identification of the exact contours of rich zones, containing gold of a higher size, for their prior extraction. Objective. The research is aimed at improving the technology for the combined development of complex-structural alluvial gold deposits by delineating rich sand zones, selecting a set of equipment to ensure their high-quality prior extraction, mining of ordinary and poor sand zones using in-situ leaching technology. Results. The paper proposes an improved development technology, which consists in identifying zones of rich sands and subsequent refinement of their contours, prior mechanical extraction of rich sands, containing a significant amount of relatively coarse gold using an extraction module, with the extraction of the rest of the rich sands using hydraulic borehole mining, and ordinary and poor areas using in-situ leaching. The extraction module is installed on the stem of the drilling rig and includes cutting elements, rods, a hydraulic drive, and a bucket. The rich sands extracted to the surface are supplied for multi-stage enrichment. The remaining main volume of the deposit is mined using in-situ leaching solutions with adaptive concentrations that provide a relatively high recovery of gold into the product solution. Conclusions. The use of the proposed combined technology will significantly reduce technological losses and increase the extraction of gold from the sands of complex-structured deep-seated placers, while reducing the unit cost of gold mining.

. Having analyzed the issue of the study on various approaches to management of metallurgical enterprises, the authors set an objective: to determine the most efficient management system for the Group of Budget Planning and Current Assets Management of OJSC MMK-METIZ. The budgeting system used at the enterprise was analyzed with the identification of main disadvantages. It was determined that management, using the enterprise budget as the only one criterion for achieving strategic goals, did not provide an assessment of an intangible component of success of the enterprise performance. The authors describe a system of key performance indicators (KPIs), which reflects the transformation of the company’s strategy into a set of interrelated and balanced performance indicators. Developing meaningful key performance indicators that track and clearly visualize performance requires definite planning. Every indicator should correspond to a specific business process and provide timely and accurate information to assess the progress towards achieving goals. A system of key performance indicators has been developed for the Group of Budget Planning and Current Assets Management of OJSC MMK-METIZ. The authors determined main business processes of the Group of Budget Planning and Current Assets Management of OJSC MMK-METIZ and its performance indicators. The implementation of the KPI system will provide the company with the opportunity to determine strategic, financial and operations goals of the company based on clear indicators of efficiency of business processes, contributing to optimizing effort of all the departments. Monitoring of the company’s activities will be reduced not only to the analysis of deviations of business indicators from planned figures, but also to the assessment of the current results of achieving strategic goals. The KPI system will motivate the staff to improve efficiency of their activities in general.

. Problem Statement (Relevance). The use of cylindrical gears with arc teeth in locomotive drives, final reduction gears, and upper drives of drilling rigs makes it possible to increase manifold the service life of gears in comparison with spur and helical gears. There are currently proposed ten and a half methods of manufacturing arc teeth of cylindrical gears, differing in tools and shaping movements. A method of cutting arc teeth with cutter heads using the irregular division method on CNC machines is most advanced for industrial manufacturing of cylindrical gears with arc teeth. At the same time, studies on kinematic characteristics of gears, whose teeth are cut in this way, when working under conditions of errors, have shown that the position function has a sawtooth shape, and the teeth clash when meshing. To ensure approximate gearing, it is necessary to perform a profile modification of the tooth flank by using a cutter head with a more complex generating surface, rather than a right circular cone. Methods Applied. A mathematical model of the cutter head generating surface and formulae for calculating its geometric characteristics were developed by applying differential geometry and spatial gearing theory methods. Originality . The authors obtained dependence for coordinates of a radius vector and a unit normal vector, principal curvature of surface points, for the arc cutter head with the generating surface as the one-sheet hyperboloid. Result. The developed mathematical model of the cutter head generating surface contributes to modifying the gear arc teeth profile for both generating gear and gearing with rectilinear flank toothing options, when processing the concave side of the arc tooth. Practical Relevance . The use of circular cutter heads with a one-sheet hyperboloid generating surface ensures approximate gearing by modifying the arc tooth profile subject to errors in the gear and pinion relative position.

. Problem Statement (Relevance). Currently, industrial robots are used in the industry as part of robotic complexes for machining large-sized parts made from composite materials and metals. For example, control panels of electric locomotives, three-dimensional curved shells, etc. The existing methods for designing a rotary machining operation based on robotic complexes follow the empirical selection of cutting conditions for every specific product; therefore, they are limited in their versatility. The lack of methods for the reasonable assignment of cutting modes and the choice of a cutting tool, taking into account the assessment of the oscillatory process in the technological system during machining on the basis of robotic complexes, negatively influences both the output of machining (downgrading of machining modes in order to ensure accuracy and quality) and time required to introduce the parts into production.

The paper studies the oscillatory processes in the technological system and the possibility of taking them into account when developing a methodology for designing a machining operation with rotating tools based on a robotic complex.

Practical Relevance . The research carried out makes it possible to determine rigidity of the technological system of the robotic complex by test machining of parts, which will contribute to a subsequent assignment of cutting modes that provide the specified accuracy at maximum performance.
