The influence of technological parameters on selected surface roughness parameters during aluminum 7075 alloys turning

Abstract: Analiza literatury -stan zagadnieniaSkrawalność stopów aluminium zależy głównie od ich składu chemicznego i struktury stopu ukształtowanej w wyniku obróbki cieplnej. Zawartość krzemu (Si) w stopie w ilości ok. 10% stanowi istotną granicę skrawalności, ze względu na zużycie ostrzy narządzi. Na chropowatość powierzchni mogą wpływać m.in.: materiał narzędziowy, jakość wykonania narzędzi, geometria ostrza, właściwo-ści materiału obrabianego, powłoki ochronne, parametry technologiczne (największy wpływ na jakość po… Show more

“…Surface roughness parameters that are frequently under analysis in research papers, Ra and Rz, do not exceed the level of approximately 2µm and 10µm at any cutting speed. Increase in feed results in linear increase in the surface roughness parameters, which is in accordance with the common theoretical relationship expressed by Rz t =f 2 /8r ε [18]. It may be inferred that surface quality will improve when cutting is carried out with a suitable PCD tool.…”
