Abstract: As enterprises facing tremendous time-to-market pressures, manufacturing systems must be implemented quickly and reconfigured easily. The advent of open architecture Computer Numerical Control（CNC） is to address these challenges, while the open architecture CNC should be based on international standards and ‘de facto’ standards. There is no truly open architecture CNC if there is no related standard. The architecture and the interfaces in the open architecture CNC were summarized. Meanwhile, the standards and the protocols applied in interfaces of all sorts were described and their characteristics were presented. The advantages and disadvantages of the same kinds of standards were also compared . Finally, an overview on the current practices and the desired future of the related standards was given.

Key words: open architecture, computer numerical control, standard, interface
