Abstract
The turning process is the most widely used manufacturing process in machining industries. All mechanical equipment has many components manufactured entirely by the turning process. In addition to being highly versatile, the turning process produces mechanical parts with excellent surface quality. Surface roughness is one of the main evaluated parameters in manufacturing after manufacturing, especially in turning processes. There are several surface roughness monitoring parameters, with the Ra valor being the most used in industries. This work conducted experimental turning tests with ceramic tools, varying the feed, cutting speed, and tool nose radius. The authors have chosen cutting parameters considering the parameters recommended by the tool supplier. The cutting forces during the experiments were also analysed: Speed Force, Feed Rate Force, and Passive Force. The results showed that the feed rate and tool nose radius were the most influential input parameters on surface roughness. On the other hand, the cutting speed has a modest influence on the surface roughness behavior. In the case of cutting forces, the cutting speed and the tool nose radius were more influential on the Passive Force, while for the Cutting Force, the most influential parameters were the cutting speed, the tool nose radius, and the Feed Rate Force. For Feed Rate Force, the most significant parameter was the feed rate. It can be concluded that the surface quality remained stable with the variation of the cutting speed, allowing the production of parts with a high cutting speed with satisfactory quality. Furthermore, the Cutting Efforts showed a standard behavior for the variation of the studied parameters.
