Pengaruh Pembubutan Dengan Sistem Minimum Quantity Lubrication (MQL) Dan Dry Cutting Terhadap Kekasaran Permukaan Dan Konsumsi Daya Listrik Pada Baja Karbon Sedang

Background of research on the effect of turning with the method of minimum quantity lubrication (MQL) and dry cutting on surface roughness and electrical power consumption in medium carbon steel. The purpose of this study was to determine the effect of turning with minimum quantity lubrication (MQL) and dry cutting and to determine the electrical power consumption of the lathe to improve surface roughness. In the industrial world repairing surface roughness of work pieces is preferably using turning process so it is necessary to find a cooling medium that can reduce high temperatures, so as to improve surface roughness, reduce tools and find methods of improving surface hardness that are good and efficient in the use of electric power in the process turning of medium carbon steel. Stages in analyzing surface roughness in the turning process using the method of minimum quantity lubrication (MQL) and dry cutting. The right method is obtained to reduce the level of roughness in the turning process, using the minimum quantity lubrication (MQL) method.
