Shrinkage Factor Analysis in the Dry Machining of UNS A92024 Alloy by FEM

Chip evacuation becomes a relevant factor in the dry machining of aeronautical aluminium alloys, either when they are machined as isotropic material or hybridized with other materials. morphology and geometry highly depend on cutting parameters. Several works can be found literature focusing analysis chip alloys at high speeds but there is lack studies that apply low speeds. FEM simulation may useful to reduce experimental time cost this kind analysis. Therefore, work, influence feed-rate several geometrical parameters (height peaks, height valleys shrinkage factor) turned UNS A92024 alloy has been analysed by simulation. Three different energy fracture modes have tested damage evolution criterion, order get mode better fit morphology. In general, mixed was best suited behaviour, within wider range.
