Study of Cutting Force When Milling SKD61 Steel Using Minimal Lubrication of Sesame Oil

This study focuses on evaluating the influence of SKD61 steel milling process parameters using CBN tools on the cutting force components when milling. The milling process used minimum quantity lubrication (MQL) emulsion, sesame oil and dry machining for control evaluation. Components of cutting force when milling are measured by a 3-component shear force measuring device of Kisler, Switzerland. Experiments are carried out with the plain milling process, the workpiece is mounted on the ETO. The cutting process was surveyed for more than 50 minutes. Initial results show that the cutting force increases slowly when the cutting process is done up to 30 minutes (increasing about 100N). After this period, with all cooling lubrication methods, the force increases sharply. However, the cutting force when using cooling lubrication is lower than in dry machining; The process of using sesame oil MQL results in the lowest, slowest, and most stable cutting force. This shows the positive effects of the cooling lubrication process, especially the sesame oil MQL process, on the cutting force components during milling
