Abstract：

The　coated　(TiCN,　TiAlN)　and　uncoated　carbide　end　mills　of　ultra-fine　grain　were　adopted　for　high-speed　milling　of　carbon/epoxy　composite.　First,　the　expansion　and　the　law　of　tool　flank　wear　were　investigated.　Then,　the　variation　of　cutting　force　and　burrs　with　the　trend　of　tool　wear　were　analyzed.　The　microscopic　morphology　of　the　tool　wear　was　observed　and　the　wear　mechanism　of　the　tool　was　analyzed.　The　results　show　that:　the　uncoated　tool　obtains　the　largest　flank　wear　and　cutting　force,　and　the　expansion　of　burr　is　severer　than　the　other　two　under　the　same　cutting　conditions.　The　flank　face　mainly　suffers　abrasive　wear.　Micro-chipping　is　observed　to　be　the　tool　failure　ascribed　to　the　negative　effects　of　adhesive　wear　and　oxidation　wear　on　the　main　cutting　edge.　TiCN　coated　tools　mainly　suffers　abrasive　wear,　accompanied　adhesive　wear　and　slight　oxidation　wear,　while　the　form　of　failure　is　flaking　and　micro-chipping.　TiAlN　coated　tools　obtaining　the　smallest　flank　wear,　cutting　force　and　burrs　expansion,　are　more　suitable　for　processing　carbon　fiber　composites.　The　flank　face　mainly　suffers　abrasive　wear　while　the　main　failure　is　flaking.　©　2016,　Editorial　Office　of　CHINA　SURFACE　ENGINEERING.　All　right　reserved.
