Methodology for evaluation of centrifugal force resistance of HSC-tools by analyzing tool body deformation and cutting edge offset

For high speed milling operations the most critical load is caused by centrifugal force. The maximum operational speed has to be determined to ensure centrifugal force resistance without over-dimensioning HSC-tools. Hence, resource intensive burst tests have to be executed. This paper demonstrates a non-destructive methodology to qualify tools for high speed milling. As our research shows, it is possible to estimate the maximum operational speed by analyzing the characteristics of elastic and plastic tool body enlargement and cutting edge displacement. In addition, it will be discussed how work piece quality can be improved by considering the cutting edge offset.
