In　this　paper,　a　comparative　study　is　reported　on　tool　wear　morphology　described　by　machining　Be/Cu　alloy　at　different　cutting　speed:200　m/min,400　m/min,600　m/min,800　m/min　and　1000　m/min.　The　cemented　tungsten　carbide　tools,　both　coated　with　TiAlN,　are　used　to　test　tool　life,　and　the　flank　wear　extent　and　standard　deviation　are　adopted　to　describe　surface　wear　pattern.　In　order　to　explain　the　wear　mechanism　under　different　cutting　speed,　a　series　of　theoretical　calculation　and　experiment　results　were　listed　in　this　paper　to　explain　adhesive　effect　on　tool　wear　under　different　surface　pressure,　and　results　show　that　the　adhesions　and　wear　patterns　would　be　affected　by　cutting　speed　and　surface　pressure.　Comparing　the　relationship　between　cutting　force,　cutting　heat,　surface　elements　and　tool　wear,　we　can　easily　find　out　that　the　hard　particle　such　as　Cu　and　Be　adhered　to　cutting　edge　to　affect　tool　geometry　and　strengthen.　Besides,　the　microstructure　and　generation　probability　are　analyzed　to　discuss　the　crystal　surface　slipping　effect　on　tool　wear.　©　2019
