I’ve decided to post here a brief review of the most anticipated (at least for me) NX 11 feature which called Swept Volume.
Use the Swept Volume command to sweep a solid body along a path using various options to control the orientation of the tool with respect to the path and either subtracts it from or intersects it with a target body.
You can specify the orientation of the tool body along the path using the Sweep Orientation option.
A tool body:
-
Must be a single solid body.
-
Must not have any through holes, blind holes or internal voids.
-
Axis must intersect the tool path within the bounds of the tool body.
-
Must be created from analytical geometry.
-
Must be created as cylindrical or revolved from an axis that represents the tool axis or a sphere.
Examples of tools for planar or non-planar paths.
A tool body for planar paths may also contain:
-
Non-analytical geometry.
-
Concave faces.
-
Concave edges forming a stepped staircase profile.
Examples of tools for planar paths only.
