The article considers the prerequisites for the creation and implementation of occupational safety management systems in organizations, assessment of occupational risk levels, identifies the reasons for changes in labor protection legislation in the period from 2014 to the present, and also considers the recommendations of the Ministry of Labor of the Russian Federation on risk management and minimizing their consequences, including practical examples of their application.

The methodology for assessing occupational risks currently occupies a priority place in assessing the impact of production factors on the health of workers. The main sources of information for assessing the levels of occupational risks include data obtained in the course of state sanitary and epidemiological surveillance, a special assessment of working conditions and production control. To date, there is a need to harmonize legislation on a special assessment of working conditions and sanitary and hygienic requirements in terms of the list of factors of the working environment and the labor process subject to research and measurement. An adequate assessment of occupational risks is possible only on the basis of the use of consolidated databases on working conditions obtained from various sources.

The article considers the role of an industrial Internet platform in manufacturing enterprises. We are conducting an introductory case study, which examines the degree of prevalence of platforms in various regions of the country, examines the introduction of digital platforms at the enterprise from the point of view of investment projects, examines various definitions of this phenomenon, its goals, various classifications of projects reflecting certain aspects, studies various methods of risk assessment, and There are also indicators for evaluating the effectiveness of the implementation of digital platforms. The results of the study can be summarized from two key points of view. First, the industrial Internet platform offers manufacturing enterprises valuable technical support and potential opportunities to implement digital business transformation. Secondly, in order to effectively use these opportunities, enterprises must strategically use the technical services and systems of the platform in their production and operational practices. This study contributes to this area by expanding the scope of traditional manufacturing enterprises and presenting a model of the stage of their digital transformation using an industrial Internet platform.

Mechanical processing of machine-building parts in most cases is associated with the appearance of burrs, sharp edges, chips. To remove them, various types of equipment and tools are developed and used, a large amount of work is done manually by workers. In this paper, it is proposed to combine finishing and stripping operations performed using adjustable wire tools on multi-purpose machines using robotic manipulators. At the same time, it is proposed to use a system for monitoring the presence of burrs by machine vision processing information using a brightness-geometric model and filtering image pixels by brightness. Two variants of schemes for the organization of promising layouts of a robotic site are proposed to reduce the share of manual labor, expand the functions of robotic manipulators and the widespread use of adjustable wire tools.

This work is devoted to heat treatment of metals and alloys — the most important technological process that allows for targeted changes in their structure and properties. The work examines in detail the main types of heat treatment: annealing, hardening, tempering, normalization, aging, carburizing. For each type of treatment, a description of its essence, purposes, varieties, advantages and disadvantages, as well as areas of application is given. Particular attention is paid to factors affecting the efficiency of each process, such as temperature, holding time, cooling rate and composition of the material being processed. The work will be useful for students of technical specialties, engineers and technologists working in the field of materials science, mechanical engineering, metallurgy and other industries where heat treatment of metals and alloys is used.
