Method and apparatus for simplifying the task of retrieving and accessing a segment of a numerical control (NC) program

摘要

Long NC programs are made more manageable by assigning descriptive NC sentences to groups of program code lines of the NC program. The groups can be combined into groups of higher hierarchial order and assigned a descriptive NC sentence. The NC sentences are displayed in their respective hierarchial order and allow an operator to quickly locate a portion of NC program by selecting the appropriate NC sentence.
