This paper proposes Internet-based checking scheme for machine-tools with a variant CNC. Checking points defined in this research are classified into two categories such as structured point and operational point. The formal includes the vibration of bearing, temperature of spindle unit and another periodical management. And the latter includes oil checking, clamp locking/unlocking and machining on/off status. Through this research, for the global management of variant CNC machines interspersed with CAC and OAC in manufacturing system, the suitable environment for Internet-based checking of variant CNC machines was designed and the checking methods for CAC and OAC machines were compared with each other.

In this paper, the research activates through a R&D program developing technologies for micro-factory systems for the next generation during 1st year of the 3rd phase, year-7. In this stage, based on the developed technologies and understanding fundamental principles for micro-factory systems during the previous phases of this project, the overall direction of the launched R&D programs is towards development of practical micro-factory systems such as artificial teeth implants and μ-actuators and micro-lens systems. In order to accomplish the designed goals of this R&D program, the research groups were re-organized into three research teams according to target researches. Key technologies for next generation micro-factory systems were selected to be developed, which are BT micro-factory for dental implants and customized abutments, IT micro-factories for micro lens module and electromechanical components for mobile devices and next generation components for micro-factory. Some selected results from the researches in this ongoing R&D program were briefly covered.

Open architecture controller (OAC) is well known technology in factory automation. To better understand the requirements of OAC, authors have discussed the OAC related topics with a number of control experts who represents different segments of the machining industry. There is no common concept that is accepted or used, however, the common ideas for OAC is the control system that is hardware independent, interchangeable, and easily scalable. This paper presents summary of the understaning and requirements of OAC. Based on the requirements of OAC, authors developed the software based PC-CNC. The main focus of the PC-CNC was on the user customization capability and open interface between control networks in manufacturing system. This paper introduces the developed PC-CNC briefly. In addition to introduction of the PC-CNC, to fill the gap between end users and vendors of OAC, this paper presents two applications using OAC. One is a remote monitoring system. The OPC (Ole for Process Control) standard interface was used to monitor the status of open architecture CNC across network. The other is the remote production management module for machine tools using standard database interface.
