The cooling systems compared are: dry machining, minimum quantity of lubricant with eco-fluid (MQL-Eco), cold compressed air (CCA) and cryogenic machining. Multi-materials used are magnesium-aluminium and magnesium-titanium combinations. The study uses descriptive statistics and ANOVA to conclude the significant factors and interactions. Conclusions highlight differences depending on the type of response variable chosen. The best results for the Mg-Al-Mg are obtained using MQL-Eco, and for Mg-Ti-Mg with cryogenic machining.enAtribución-NoComercial-SinDerivadas 4.0 Internacionalinfo:eu-repo/semantics/openAccessartículoMulti-materialMachiningCoolingSustainable
