Analysis of the Geometric Shape of the Cutter in Ring-core Measurement

Estimation of the magnitude, sense and direction of the residual stress components in mechanical parts is a key factor for its lifespan and safety prediction. The principles of the semi-destructive Ring-Core method for residual stress determination are already well known. Commercially available measuring systems now enables to connect numerical and experimental evaluation techniques. Just by this appropriate connection new analyzes of evaluation accuracy by studying necessary influencing factors are formed. This paper deals about the influence of specific mill cutter geometry.
