Residual Stress Measuring at Conventional and High-Speed Milling

摘要

At the moulds and swages making happens to rise of residual stress in consequence of heat process. These problem is very significant especially at modern technology like high – speed hard milling (HSC), when happens to extreme conditions from mechanical and heat aspects. Residual stress rise depending on cutting speed, feed, tool type and other parameters is therefore one of the most important part of optimizing of he HSC process. This paper deals with evaluation of residual stress after high – speed and conventional milling. For a measuring residual stress were select two different methods. It was method measuring by method of Barkhausen noise and hole-drilling method.
