NCL is ideally suited for environments where design changes are frequent, such as the aerospace industry. NCL also supports full parametric programming where a family of parts can be machined by simply filling in a form. NCL is used extensively in the aerospace, turbomachinery, power generation, tire mold, and composite industries.
The Aerospace Applications Library includes functions to accomplish the following machining operations:
- Flange top machining
Flange tops appear in a variety of different shapes and often require a laborious effort on the part of the NC programmer to properly machine them, especially when machining harder metals such as steel and titanium. The Aerospace Applications Library provides a method by which flange tops can be machined with a bull nosed end mill in a multi-pass, climb milling fashion. These operations are easily performed by simply responding to prompts given by the system.
- Rest machining of corners
This feature automatically removes the material, using a circular machining technique, that was left by a previous tool. The system automatically calculates the number of circular passes necessary to remove the material left by a larger tool and the angle between the two walls that form the corner.
- Optimized drilling
This feature will determine the shortest path necessary to perform holemaking operations on a random set of points. The points can either be defined in NCL or imported from another CAD system.
- High speed machining of pockets
This feature allows for Z-level roughing and automatic finish profiling, including full 5-axis contouring of multiple pockets. The generated tool path will include 3D helical entries into the pockets or pre-drilled hole entry and spiral out machining.
- Gouge free 5-axis flank milling
The system provides a variety of methods by which angled planes and lofted surfaces can be easily flank milled using ball nose, bull nose, or form cutters. NCL automatically fans the tool from surface to surface without gouging the floor of the part. The Aerospace Applications Library offers the most complete and advanced 5-axis capability available.
- Full associativity between the model and tool paths
This feature is critical for programming structural aircraft parts. It allows for easy long term maintenance and optimization of NC programs. More importantly, engineering changes can be easily incorporated. When the geometry changes, associated geometry and tool paths are automatically regenerated. This feature also dramatically reduces programming time for part families and opposite hand parts.
