【 摘 要 】

In recent years, carbon fiber-reinforced polymer (CFRP) materials are gaining tremendous attention by industries especially in aerospace industry for product structures due to the superior material properties such as high strength, low weight and corrosion. This study presents a research on the influence of machining parameters utilizing uncoated tungsten carbide router or burrs tool towards surface quality during edge trimming of a specific CFRP material. CFRP panel of 10.31 mm in thickness with the total of 38 number of plies has been chosen to be the main study material. A famous statistical method namely Taguchi Method (L4) has been deployed to plan the overall experimental design. Two main factors investigated in this study were spindle speed and feed rate. Surface roughness measurement was taken using Mitutoyo Surftest SJ-410. Moreover, optical microscope Nikon MM-800 is utilized to further observe the trimmed surfaces. The result reveals that the spindle speed was the most influential parameter towards the trimmed surface quality. Run no. 3 (R3) generated approximately 2.5 times better Ra value than Run no. 3 (R2) at constant feed rate (1500 mm/min) but vary in spindle speed by the difference of 3000 rpm. From further observations of trimmed surface through optical microscope, obvious matrix degradation and wrench areas were spotted on the R2 trimmed surface compared to the R3. From ANOVA analysis, spindle speed was also indicated as the significant factor. Details results elaborated and discussed further in this paper.
