OPTIMALISASI MESIN BUBUT ( OPTIMIZATION OF LATHE MACHINE )

Abstract

Optimalisasi mesin bubut dilakukan untuk memaksimalkan setiap proses permesinan pada mesin bubut agar mesin dapat bekerja secara optimal. Proses optimalisasi mesin bubut meliputi beberapa tahapan, yaitu : pertama mengecek semua komponen dari mesin bubut apakah normal dan tidak ada kerusakan, kedua, proses penggantian komponen pada mesin bubut yang rusak di antaranya, roda gigi cacing, poros lemari norton, serta pasak tirus. Kemudian dilakukan pengujian pada benda kerja sesuai prosedur pengoperasian. Hasil yang diperoleh dari pengujian mesin bubut yaitu gaya potong 32,5 N, daya pemotongan 9,75 Watt, gaya tangensial pada saat mesin beroperasi 385,3 N, gaya tangensial pada pasak tirus 2002,02 N, serta waktu pembubutan efektif 2,52 menit. Dengan gaya tangensial lebih kecil saat beroperasi disbanding gaya yang mampu diterima, pasak sebenarnya masih dalam kondisi aman. Kata kunci : optimalisasi, gaya tangensial, daya pemotongan, gaya potong Optimization turning machine is performed to maximize every machining on the turning machine, so that the machine can work optimally. Turning machine optimization process includes several stages, First, check all components of the turning machine is normal and there is no damage, secondly, the process of replacing a component on the turning machine that is broken between the worm gear, norton box shaft, and tapered pin. Then, testing the workpiece according to operating procedures. The results obtained from testing the turning machine is cutting force 32,5 N, power of cut 9,75 Watt, tangential force at the time the machine is operating 385,3 N, tangential force on the tapered pin 2002,02 N, and the effective turning time is 2,52 minute. The tangential force smaller than the received force during operation, the tapered pin actually is still in safe condition. Keywords: optimization, tangential force, power of cut, cutting force
