Impact of disturbed drilling conditions on the surface integrity of a Nickel-base superalloy
Résumé
Manufacturing critical parts for aerospace industry requires an important validation process to guarantee the quality of the produced components, and thus their fatigue life. Even with the best cutting conditions, disturbances can occur during the process and may have a direct impact on metallurgical quality. Through an experimental approach, this work presents the impact, during machining, of a lubricant interruption on the surface integrity and on the Process Monitoring signals. Finally a correlation between the thickness of the thermo-mechanically affected layer and the cutting power is made.
