Design of PC-NC and Open CNC

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

Abstract

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.
