Machine tools, which are indispensable parts of the machinery and metal production sector, are frequently used in the sector. Workplaces in the sector are in dangerous and very dangerous classes in terms of their activities, and therefore, it is inevitable that work accidents and occupational diseases occur frequently in machine tools where production is made. For this reason, risk assessment has become the most important requirement in order to minimize the physical, chemical and ergonomic risks that already exist in machine tools and originate from use, and to establish an occupational health and safety climate in the sector. In this study, universal and CNC (Computer Numerical Control) controlled milling machines, which are used in a university laboratory, where most of the production is carried out in the sector and therefore one of the most frequently used machine tools, are discussed and risk assessment with Fine-Kinney method, which is one of the most frequently used risk assessment methods in the sector has been made. A total of 23 risks have been identified, corrective/preventive actions necessary to prevent existing hazards and reduce risks have been explained and solutions have been presented. With this study, it is aimed to raise the necessary awareness to the employees by evaluating the milling machines, which are frequently used in the sector, both in production and in the laboratories for educational purposes, in terms of occupational health and safety.
Developing technology and production needs are increasing the need for the machinery metal production sector. On the lathe machine, is one of the most widely used machines in metal production sector, work accidents and serious occupational diseases occur every year. In order to prevent this, it has become a necessity to create an occupational safety culture in general. In order to prevent the existing hazards and possible accidents in small and large enterprises in the sector, it is necessary to identify them first and to make an effective risk assessment in order to offer solutions. When making a risk assessment, it becomes clear that the risk arising from a hazard in any machine cannot be ignored, that all dangerous situations should be revealed in detail and necessary solutions should be proposed accordingly. In this study, the existing hazards and risks in terms of occupational health and safety of universal and CNC lathes used in a university laboratory were revealed, risk assessment was carried out with Failure Mode and Effects Analysis (FMEA) method and risk priority numbers were calculated. While 6 important risks and 4 fundamental risks were determined for the universal lathe, 1 possible risk, 5 important risks and 1 essential risk were determined for the CNC lathe. According to these results, corrective actions were determined to prevent hazards and solution suggestions were presented. We think that this study will make positive contributions to occupational health and safety in the use of lathes, which are both in manufacturing workshops and used for educational purposes in laboratories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
