This paper proposes an Internet-based checking technique for machine-tools with variant Computerized Numerical Controller
(CNC). According to its architecture, CNC is classified into one of two types: Closed Architecture Controller (CAC), which
is the conventional CNC, or Open Architecture Controller (OAC), which is a recently introduced PC-based controller. Since
CAC has a closed architecture, it is dependent on CNC vender specification. Because of this, it has been very difficult for
users to implement application programs in the CNC domain. Recently, the conventional CNC of machine-tools has been replaced
by a PC-based open architecture CNC. However, now many conventional CAC machines are being operated together with OAC machines
in inadequately equipped shop floors. For Internet-based checking for variant CNC machines with CAC and OAC, a suitable systematic
environment is necessary. Through this research, for the global management of variant CNC machines both a CAC and an OAC in
the manufacturing system, a suitable environment for Internet-based checking of variant CNC machines was designed, and the
checking methods for CAC and OAC machines were compared. The results of this research may serve as a base model for global
monitoring and remote control in an integrated manufacturing system with variant CNC machines. Checking points defined in
this research are classified into two categories: structured point and operational point. The former includes the vibration
of bearing, temperature of spindle unit, and other points of periodical management, while the latter includes oil checking,
clamp locking/ unlocking, and machining on/off status. 相似文献
