Machinability And Surface Quality Of Hybrid Composite CFRP/Al2024
AbstractThe use of hybrid composite has increased due to their special mechanical and physical properties. However, machining of composite materials is extremely difficult due to non-homogeneous, anisotropic and highly abrasive characteristics. The performance of machined surface quality of CFRP/Al2024 was described using two level full factorial methodology. Trimming test was performed under dry conditions using 6mm diameter of burr tools end mills. The factors investigated were spindle speed(N), feed rate(fr) and depth of cut(dc), furthermore Ra CFRP and Ra Al2024 were the response variables. This work aims to minimize the machined surface quality of CFRP/Al2024 between 1μm to 2μm. The finding of this empirical study has shown that, the best estimated value of fr should be 500 mm/min to 530 mm/min, N is between and 2313.870 rpm to 2336.042 rpm. For both response spindle speed is the most significant effect followed by Feed rate and Depth of Cut.
