Design of PC-NC and Open CNC

Part of the Springer Series in Advanced Manufacturing book series (SSAM)


Recently, industrial controllers based on PC hardware seem to have replaced conventional controllers based on a closed hardware structure. We will discuss the design issue of PC-NC running the NC functions described in other chapters on a personal computer (PC). The hardware architecture, software model, and communication mechanism for building PC-NC will be addressed. In particular, Soft-NC, where a single processor is used and all functions of PC-NC are implemented as software tasks, will be described. In addition, an open CNC architecture supporting openness of H/W and S/W of CNC systems will be discussed.
