Content

Reaming is commonly used in industry to accurately enlarge and smooth the internal finish of a premachined hole. As holes are critical areas for the fatigue resistance, this paper investigates the influence of some technological parameters, such as back taper and tool holder flexibility, on the surface integrity induced by reaming of a 15-5PH martensitic stainless steel. Residual profiles and hole’s geometry are correlated to cutting forces measurements thanks to an original experimental set-up. This work highlights the high sensivity of residual stress profiles to back taper and tool holder flexibility.


This presentation was given during the 6th CIRP Conference on Surface Integrity and won the Best Young Scientist Award.
