A new approach to the prediction of temperature of the workpiece of face milling operations of Ti-6Al-4V
Résumé
The machining of titanium alloys is critical because of high temperature reached at the tool nose, the segmentation of chip that causes chipping of the tool. The strategy used in the job shop is to use low cutting speed (50-70 ) and high feed rate (0.1-0.2 ) in flooding condition in order to reduce the tool temperature and avoiding chipping. The edge preparation and the coating play an important role from thermal point of view. In particular a right compromise between sharp edge and the needs of the coating has to be taken into account.
