Technological parameters influence on biodegradable injected polymers during water jet cutting

"Arbofill Fichte and Arboblend V2 Nature are polymers with high-performance functional characteristics and which have the potential to replace plastics based on nonrenewable resources from various sectors of activity. The present study aims to analye from topographical point of view the behavior of injected parts during the processing by cutting with abrasive water jet. The materials behavior, as expected, in any machining or manufacturing process is influenced by the technological parameters, whether they are kept constant (for example the part thickness, the abrasive material, the distance between the cutting head and the part) or variable (pressure, traverse speed and abrasive material flow). In this sense, the purpose was to obtain data regarding the most used roughness parameter, Ra, and based on them some solutions for optimizing the working parameters will be provided, so that the surfaces quality to be as good as possible. The results showed that the technological parameter ""abrasive material flow"" has the greatest influence on the roughness, ie lower values of roughness for the situation of using a larger amount of abrasive.
