Abstract: To develop special Numerical Control (NC) machine controller conveniently, open architecture special Numerical Control (NC) system was researched as the platform, which could be used to accessing third party devices and doing interconnection and interoperation. Function model, data model, architecture model and behavior model of open special NC system were proposed, and the distributive open architecture special NC system was realized based on multi-CPU embedded system structure. Dual data areas synchronization scheme was adopted to solve the data synchronization maintenance problem of distributed system. The proposed system was applied to a bearing ring NC turning center successfully, and the expected target of trajectory's parameter variable program control for this NC machine was realized.

Key words: open architecture, special numerical control system, interoperation, system model
