i am working on the project of study of machinability of Alluminium 6061, zirconium, fly ash composites. before i take a step ahead i want to get some details about how the results of this alluminium alloy vary as it is subjected to machinining considering zirconium is fed 0% 2% 4% 6% 8% 10% respectively for the 1 2 3 4 5 6 allumunium alloy specimens
