Abstract

This work presents the results of experimental research regarding cutting force, chatter frequency and amplitude for different cooling conditions in profiling of AlCu4MgSi aluminium alloy. The following conditions were analyzed: dry cutting, cooling with water-based emulsion, MQL and MQCL. It was determined that cooling and lubricating conditions in the cutting zone have a minimal effect on machining forces in the following range of parameters: cutting speed 300–600 m/min, depth of cut 1–2 mm, feed rate 0.1–0.5 mm/rev. Therefore, a conclusion to introduce dry machining to cut down costs was formed. Changes in cutting force components can be described by the following relation: Fc ≈ Fp > Ff. The intensity of the effect of technological parameters on cutting force components decreases in the direction of f  ap → vc. It was proven that by analyzing changes of cutting force in machining time, possibilities of chatter occurrence for different machining conditions can be assessed.
