"Guards on machine tools are meant to protect operators from injuries caused by tools, workpieces, and fragments hurled out of the machine's working zone. This article presents the impact resistance requirements, which guards according to European safety standards for machine tools must satisfy. Based upon these standards the impact resistance of different guard materials was determined using cylindrical steel projectiles. Polycarbonate proves to be a suitable material for vision panels because of its high energy absorption capacity. The impact resistance of 8-mm thick polycarbonate is roughly equal to that of a 3-mm thick steel sheet Fe P01. The limited ageing stability, however, makes it necessary to protect poycarbonate against cooling lubricants by means of additional panes on both sides."

"Guards on machine tools are meant to protect operators and bystanders from injuries caused by tools, workpieces, and fragments hurled out of the machine's working zone. When the protective guards cannot withstand the impact of these high-speed objects, workers can be injured. Future European product standards will set forth clear requirements for the impact resistance of guards, and draft standards now exist for turning machines, milling machines, machining centers, and grinding machines. The machine-specific impact resistance requirements presented in this article can help you specify the material and dimensions for guards on your machine tools."

"Com a introdução da robótica e das novas tecnologias nas grandes empresas dos países industrializados, os riscos mecânicos vem sendo gradativamente superados e substituídos por outros riscos mais diretamente relacionados à organização do trabalho. Um grande número de indústrias com utilização de tecnologias e máquinas obsoletas tem sido exportadas para os países em desenvolvimento. Nos processos tecnológicos mais avançados, onde ocorre a introdução da robótica, são os trabalhadores de manutenção os mais expostos aos riscos mecânicos. ..."
