Application of water jetfor cutting polymer materials

Abstract

Due to the nature of polymeric materials, during thermal cutting processes it leads to their melting, and therefore appear errors in the final product. This paper presents a “cold” process of cutting polyamide 6 ie. SIPAS 60, where there are given the characteristics of materials and guidelines for satisfactory quality of process. The authors made the cut experiment 32 were they changed the cutting parameters (cutting pressure, cutting feed and abrasive mass flow); the surface roughness was measured by the depth of material, because the roughness changes with the thickness of the material to be cut.
