OPTIMALISASI MESIN BUBUT

Optimizationturning machineis 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, nortonbox shaft, and tapered pin. Then, testing the workpiece according to operating procedures. The results obtained from testing the turning machine is cutting force 29,36 N, power of cut 8,8 Watt, and the effective turning time is 1,21minute.The tangential force smaller than the received force during operation, is still in safe condition. Keywords: optimization, tangential force, power of cut, cutting force 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. Kemudian dilakukan pengujian pada benda kerja sesuai prosedur pengoperasian. Hasil yang diperoleh dari pengujian mesin bubut yaitu gaya potong 29,36 N, daya pemotongan 8,8 Watt, serta waktu pembubutan efektif 1,21 menit. Dengan gaya tangensial lebih kecil saat beroperasi dibanding gaya yang mampu diterima. Kata kunci : optimalisasi, gaya tangensial, daya pemotongan, gaya poton
