ASPECTOS DE SEGURANÇA NA UTILIZAÇÃO DE FERRAMENTAS ABRASIVAS NO PROCESSO DE RETIFICAÇÃO FACE AO DESENVOLVIMENTO TECNOLÓGICO DE MÁQUINAS-FERRAMENTAS

Abstract

The large number of variables involved in the grinding process and the use of numerically controlled machine tools has generated a new claim on safety procedures for this manufacturing process. Besides, the development of new materials to be machined, cutting tools with improved properties, as well as the increased cutting power in grinding machines demand new requirements on safety guidelines of the abrasive processes. The purpose of this paper is guide and instigates grinding machine operators to the adoption of safety procedures, considering the new technologies applied on the grinding process over the years. The topics discussions of this paper are based on the safety standards recommendations used for grinding wheels. Using of safety practices enables the risks minimization to the operator, independently of abrasive process variation and can be applied to most jobs and work situations. Keywords - grinding machines, grinding wheels, safety standards.
