The NIST RS274/NGC Interpreter - Version 3

Abstract This report describes an interpreter which reads numerical control code and produces calls to a set of canonical machining functions The interpreter is a software system written in the C++ programming language The output of the interpreter may be used to drive 3 - axis to 6 - axis machining centers Input to the interpreter is RS274 code in the dialect defined by the Next Generation Controller (NGC) project, with modifications The interpreter may be compiled as a stand - alone computer program or may be integrated with the NIST Enhanced Machine Controller (EMC) control system Input can come from a file or from a user typing on a computer keyboard Output commands can either be printed for future use or be executed directly on a machining center The report includes a full description of the RS274/NGC input language and the canonical machining functions called by the interpreter It is a complete users manual
