Abstract

This report describes an interpreter which reads a file of numerical control code for a coordinate measuring machine (CMM), produces calls to a set of canonical CMM functions, and writes inspection report files. The interpreter is a software system written in the C++ programming language. The function call output of the interpreter is being used to drive a coordinate measuring machine in the NIST Next Generation Inspection System (NGIS). Input and output files for the interpreter are in the DMIS language. The interpreter may be compiled as a stand-alone computer program or may be integrated with a NIST Enhanced Machine controller (EMC) control system used to control the NGIS. The canonical CMM functions were devised for use with the interpreter and are described in the report.The interpreter includes C++ code for parsing automatically generated from a YACC grammar for DMIS written for use with the interpreter and C++ code for feature fitting provided by the NIST Algorithm Testing System. Only part of the DMIS language is implemented in the interpreter. This second version of the interpreter includes declaration and use of variables and does not require commercial software to operate, as the first version did.
