In　this　paper,　an　integrated　product-oriented　CAPP　system　is　presented　with　its　general　architecture　and.　working　principle.　The　research　on　product-oriented　integration　CAPP,system　aims　mainly　at　middle　and　small　enterprises　to　develop　a　CAPP　system　of　network-based　which　realizes　an　organic　integration　with　other　function　systems　such　as　CAD,　CAM,　PPS,　etc.　The　key　techniques　of　product-oriented　integration　CAPP　system,　such　as　the　message　detect　of　real　time,　the　selecting　of　optimization　process　plan,　the　architecture　of　global　dynamic　database　have　been　described　in　detail.　Meanwhile,　the　network-based　database　built　in　the　CAPP　system　is　linked　with　the　enterprise　environment　smoothly　to　share　process　message　in　the　product　lifecycle.
