The Effects of Cutting Parameters on Surface Texture of Hybrid Composite CFRP/AL2024

摘要

The use of hybrid composite materials has increased due to their special mechanical and physical properties. However, machining of these materials is extremely difficult due to non-homogeneous, anisotropic and highly abrasive characteristics. The performance of machined surface quality of CFRP/A12024 was described using two level factorial methodology. Thisresearch aims to study the interaction effects and significant factors of cutting parameters on the surface quality and optimise the cutting parameter for the surface quality of CFRP/A12024 1μm to 2pm.The trimming process test was performed under dry conditions using burr tools 6mm diameter of end mills. The factors investigated were spindle speed(N), feed rate(fr) and depth of cut(dc), meanwhile profile roughness parameters(Ra)of CFRP and A12024 were the response variables. Results show that the best estimated value of frshould be 500 mm/min to 530 mm/min, N is between and 2313.870 rpm to 2336.042 rpm. Forboth responses,N is the most significant effect followed byfr and dc.
