Abstract

Results of experiments to measure induced drilling stresses in the center-hole method of residual-stress measurement are described. Five specimens of different metals were specially prepared in an attempt to relieve malerial residual stress. Surface-residual-stress measurements were then performed by the center-hole method with a conventionally used (low-speed) end mill and an ultra-high-speed drill. For each specimen, the relieved strains due to the hole drilling were significantly higher for the low-speed end mill than for the ultra-high-speed drill. Preliminary conclusions are that the ultra-high-speed drill would be much superior to the conventional low-speed end mill in the measurement of residual stress by the center-hole method.
