Design and implementation of CNC controllers using reconfigurable hardware

The reconfigurable hardware has been widely applied in Computer Numerically Controlled (CNC) systems. The reconfigurable hardware provides high performance and flexibilities for the designer. This work presented a novel CNC controller architecture using reconfigurable hardware. Several logic modules, including a new resampling module for threading, are designed to support the reconfiguration process. By employing different type of logic modules, the hardware logic of the controller can be changed to control various targets. An experimental system was built, and applied to a milling machine and a lathe machine to valid the proposed architecture.
