The article presents the results of a study of the impact of vibration load on milling machine operators in real production conditions. The relevance of the topic is due to the growing technogenic load on employees of machine-building and metalworking enterprises, where the intensive use of milling equipment is accompanied by the impact of harmful physical factors, in particular local and general vibration.

The aim of the study is to quantify the levels of vibration load and analyse its impact on the functional state of the workers' body. The study used instrumental methods of vibration measurement in accordance with DSTU ISO 5349, as well as a questionnaire survey of operators and an assessment of complaints about vibration discomfort. To ensure an objective study of the impact of vibration load on the body of milling machine operators, a series of instrumental measurements of local vibration parameters at workplaces was carried out. The measurements were carried out using a three-axis vibrometer at the control points of contact between the operator's hands and the equipment elements. The assessment was based on the vibration acceleration normalised by the root mean square value.

The results of the study showed an excess of permissible levels of local vibration at a number of work points, which can contribute to the development of vibration sickness and a decrease in performance. A number of preventive measures have been proposed, including technical modifications of equipment, regulated working conditions and the introduction of personal protective equipment.

The data obtained can be used to optimise working conditions, develop production control programmes and occupational risk management systems at industrial enterprises.
