To Create a Mill Surface
1. Click Manufacturing > Mill Surface to create a mill surface. Creo NC enables the icons for only those features that are relevant for the manufacturing model.
2. Do any of the following to add a feature to the mill surface:
Click Mill Surface > Extrude to create an extrude feature. Alternatively, click Model > Extrude. Extrude allows you to create a feature by projecting the section from the sketching plane.
Click Mill Surface > Revolve to create a revolve feature. Alternatively, click Model > Revolve. Revolve allows you to create a feature by revolving the sketched section around a centerline from the sketching plane into the part.
Click Mill Surface > Sweep to create a sweep feature. Sweep allows you to create a feature by sketching a trajectory and then sweeping a cross section along it.
Click Mill Surface > Swept Blend to create a swept blend feature.
Click Mill Surface and the arrow next to Sweep and select Helical Sweep. Alternatively, click Model > Cut & Surface > Shapes > Helical Sweep to create a helical sweep feature. Helical sweep allows you to create a feature by sweeping a section along a helical trajectory.
Click Mill Surface > Shapes > Blend and select any option to create a blend feature. Alternatively, click Model > Cut & Surface > Shapes > Blend. Blend allows you to create a feature that consists of a set of planar sections that are connected by transition surfaces to form a solid.
Click Mill Surface > Round to create a round feature. Alternatively, click Model > Cut & Surface > Shapes > Engineering > Auto Round > Round. Rounds are a type of edge treatment feature in which a radius is added to an edge or edges, an edge chain, or between surfaces. Surfaces can be solid model surfaces or traditional Creo Parametric zero-thickness quilts and surfaces.
Click Mill Surface > Datum to create advanced features. Advanced features are features with complex shapes, for example, datum curves or multiple trajectories.
Click Mill Surface > Fill to create a planar datum surface by sketching the boundaries.
Click Mill Surface > Sloped to create a mill surface that only includes surfaces above or below a user specified angle.
Click Mill Surface > Machinable Area Reference to create a mill surface to represent the area that can be milled by a tool or the area that tool will leave unmachined when the tool path is complete.
Select a surface that you want to copy and click Manufacturing > Copy to copy the surface. Click Manufacturing > Paste. The feature creation tool of the original feature opens. The Copy option is especially instrumental in Creo NC, as it allows you to reference the geometry of the design model.
Based on the feature that you want to add, Creo NC displays the corresponding dashboard. Specify the necessary details to create the feature.
 
* You can also create a Mill surface while defining a Surface milling NC sequence.
