About the Typical CNC Data Flow
The Good:• Works
• Expected and familiar
The Bad:• No high-level process information at machine
• Data standards are weak and primitive
• Reinforces existing practices
• Work-arounds are limited and non-standard
Consequently:• Advanced CNC capabilities underutilized
• Data is non-portable
• Larger infrastructure required
• Equipment standardization not seen as important

• A part of the ISO suite of STEP (STandard for the
Exchange of Product Data) standards
• A standard way of transmitting process and geometry
information to/from CNCs and CAM systems

About Advanced CNC Data Flow
• The Good:• High-level process information available at machine
• Well-defined, modern data structure, optimized for
modern data storage/transmission capabilities
• The Bad:• Not yet in production use
• Unexpected and unfamiliar

Archiving/Long Term Support
• Aircraft have long life spans, but must still
be supported
• Support becomes more challenging over time• Aircraft no longer in production
• Infrastructure no longer available
• Old, low-level process information (“G-code” data) of
little use
• Using STEP-NC, process information is preserved
• Complete redevelopment of process avoided
