Paper Abstract

The high speed milling experiments are performed for hardened H13 die steel by using coated ball end milling cutter, the experiment was design for testing distribution properties of the residual stress in HSM. And the residual stress of the work-piece surface on the feed and cross feed direction are measured by the X-ray stress analyzer (X-stress 3000), and the distribution characteristics of residual stress is analyzed. The result shows that the residual stress presents gradient distribution on feed direction, and furthermore, the three-dimensional surface micro topography has been observed by the WykoNT9300, it shows that the micro topography has no close relation with the residual stress. In addition, the cumulative effect is discussed for explaining the phenomena. It could be one explanation for the residual stress gradient on the machined surface on mechanism.
