Study on NC programming technology based on STEP-NC

STEP-NC is a new CNC data interface based on STEP.The paper gives a brief introduction of STEP-NC,and then analyzes the structure and the application of STEP-NC files.Considering the practical principle,a translator which can trans- late STEP-NC data into G code is presented.Finally,the general idea about the system development and the concrete realiza- tion method are also introduced in this paper.
