The　integration　is　a　crucial　step　to　improve　visual　design　and　analysis　management　in　the　product　development　process.　The　CAx/PDM　information　management　and　integration　was　analyzed　to　build　a　special-purpose　project　platform.　It　was　used　in　digital　design　for　swinging　angle　milling　head.　Using　the　integrated　structure　of　PDM　and　CAx,　the　platform　is　able　to　achieve　data　information　management　and　transmit　of　machine　functional　parts.　The　integrated　management　of　swinging　angle　milling　head　is　an　important　basis　of　machine　design,　analysis　and　manufacture.　Feasibility　of　the　platform　was　verified　by　applying　in　data　information　integration　of　machine　tool　plant.　©　2010　IEEE.
