ANALYSIS OF FLEXIBLE BARRIERS USED AS SAFETY PROTECTION IN WOODWORKING

Authors: Ana Pavlovic, Cristiano Fragassa

Abstract: Machine tools use physical barriers, made by flexible thermoplastic materials, to protect the environment and the operators against the projections of wood chips and parts of cutting tools. These barriers constitute a partial closure and allow the passage of the workpiece, being simultaneously able to contain sharp fragments projected at high speed. The present research was conducted with the aim to evaluate the real effectiveness of these barriers, to investigate their dynamic behaviour by numerical simulations. Results showed that these barriers, if properly considered, could retain heavier masses and higher speeds. The research also allowed, in fact, to investigate the influence of several factors in design, selection and use, as material, shape, position, assemblages and many others, highlighting weaknesses and identifying possible measures to increase its effectiveness.

Keywords: flexible barrier, aramid fibers, projection of tool parts, safety in woodworking
