Abstract: Aiming at the decoding of STEPNC program in XML format, detailed study was conducted as to the XML documents which comply with the grammar rules of integrated_cnc_schema. For its internal mapping, DOM document tree was generated by DOM interfaces between the XML and VC ++. After the completion of decoding, machining feature information and technology information of the document tree were extracted. Next, the tool path was planed by the controller according to the information extracted. Finally, through the processing of cavity characteristics, the simulation results prove the feasibility of the design successfully.
Key words: STEPNC standard; extensible markup language(XML); NC controller
