airfoil_1.jpg The Knowledge Fusion Airfoil Banding Feature automates design and creation of airfoil banding envelopes. The airfoil banding envelope is the shape of the airfoil caste designed to maintain surface curvature requirements while accounting for material shrinkage during the airfoil casting process.	airfoil_2.jpg The complete set of engineering rules required to generate the banding envelope is encapsulated within the Airfoil Banding Feature. When applied, the Airfoil Banding Feature presents a simple user interface that guides the designer through inputting required geometry and numeric parameters for design of the banding envelope.	airfoil_3.jpg Engineering parameters such as trailing edge extension (analogous to adding machining stock) and variable distance surface offset at specified locations can be easily manipulated using the specialized user interface. Knowledge Fusion features in Unigraphics are fully associative and can easily edited, allowing the designer to quickly make adjustments to necessary inputs.	beam1.jpg Knowledge Fusion allows engineers and designers to easily capture, apply, and reuse engineering knowledge. In this example, engineering rules are captured in a Knowledge Fusion Fuselage Beam Feature that automates intelligent design of aircraft fuselage beams.	beam2.jpg Knowledge Fusion enables the fuselage beam feature to recognize piping configurations and accommodate positional variants. Notice that after repositioning the beam, the beam feature automatically updates relative to its interaction with the piping. The beam feature has recognized that it does not interact with the angled pipes, as a result, through holes for these pipes are not created.	beam3.jpg

Catia_interop1.jpg Knowledge Fusion enables intelligent interoperability with foreign CAD data. Irregardless of a part’s originating CAD system, the Unigraphics NX knowledge engine manages associativity between foreign CAD parts and any new features or relationships added to it in Unigraphics NX. When the foreign CAD part is edited in its native system and re-accessed in Unigraphics NX, features and relationships are maintained and automatically updated.	Catia_interop2.jpg In this example the bracket is from a foreign CAD system, while the rear body panel and bumper are native to Unigraphics NX.	Catia_interop3.jpg An assembly has been created in Unigraphics NX with fitting and alignment relationships between: - The body panel and bracket - The bumper and bracket Unigraphics NX blend features have also been applied to complete the as-manufactured shape of the bracket. Notice that the bracket is quite long and the bumper is a quite far from the body panel.	Catia_interop4.jpg	Catia_interop5.jpg The bracket is modified in its originating CAD system to shorten its length and simplify its detail by removing a bead. When the new version of the bracket is accessed again in Unigraphics NX, the features and relationships applied in Unigraphics NX maintain associativity and update accordingly. Notice that the blend updated on the bead and that the fitting and alignment relationships in the assembly are properly maintained.	Catia_interop6.jpg

UDF_crankshaft.jpg Knowledge Fusion can simplify the design of connectors by incorporating engineering rules related to performance, material properties, and critical engineering parameters into the design process – in this specific example we are designing an engine crankshaft spline connector. Engineering rules typically consist of pre-established formulae and properties accessible in corporate databases.	UDF_crankshaft_2... Knowledge Fusion Features provide intelligent engineering feedback based on design decisions. Here, Knowledge Fusion recommends to change either the length of the crankshaft spline connector or material type based on calculations per the current design configuration.	UDF_crankshaft_3... Designers can easily react to Knowledge Fusion guidance to ensure products perform predictably. Here, engineering parameters and material selection have been balanced to ensure the performance is optimized.	Wheel_configurat... Design of complex products can be easily automated with Knowledge Fusion. Products, like wheels, can be designed quickly by defining product specifications through a simple user interface – tire width, aspect ratio, and rim diameter. Once product specifications are defined, Knowledge Fusion calculates and outputs essential product attributes - weight, cost, maximum stress, and geometric shape	Wheel_configurat... Knowledge Fusion automatically accesses design parameters, such as material properties, cost formulae, and design configurations, in databases to calculate and output the wheel geometry and other essential product attributes.	Wheel_configurat... After a product has been designed, specifications can be easily changed; and, the product automatically takes on a new form with new product attributes. Notice that this new wheel has additional spokes, and the weight, cost, and maximum stress are also different.
