@thesis{thesis, author={SALSABILA FUAD}, title ={ANALISIS PENGARUH PARAMETER PROSES DRILLING TERHADAP KEKASARAN PERMUKAAN DINDING LUBANG MATERIAL KOMPOSIT E-GLASS RESIN POLYESTER}, year={2021}, url={http://eprints.stta.ac.id/2307/}, abstract={Drilling process is a machining process that is often carried out in the manufacturing process and aircraft maintenance. Drilling process is carried out with very accurate work on aircraft material, which is evaluated based on performance characteristics such as surface roughness and related to cutting parameters such as cutting speed and feed rate, so an analysis is nedded to determine the parameters used in the drilling process to improve quality of the results drilling process. This research is focused on composite materials used in aircraft. The method used is to look at the results of the surface roughness value on the hole walls as a result of the drilling process using drilling parameters such as cutting speed and feed rate. The specimen used in this study is a composite E-Glass fiber with the direction of the orientation of the fiber using an angle of 90o and an angle of 45o with polyester resin, respectively. The results showed that the lowest surface roughness value on the hole wall was 28.97 µm in the drilling process parameter Rpm 1860 FR 0.038 and the highest was 37.78 µm in the drilling process parameter Rpm 4540 FR 0.076. From the analysis results of testing the surface roughness value of the hole wall from the drilling process using a milling machine with HSS chisels on the E-Glass fiber polyester resin composite material, that the smaller the engine rotation speed and the feed rate, the smaller the resulting surface roughness value} }
