Abstract

This report describes an interpreter which reads numerical control code and produces calls to a set of canonical machining functions. The interpreteris 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 NextGeneration 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 comefrom 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.
