4th-axis wrapping enables you to wrap a 2.5D feature around either the X or Y axis. You must have a machine with 4th-axis capabilities to use this feature.
4th-axis wrapping uses the rotary table as a continuously moving axis. Rotation occurs during the machining operation and the tool movement is limited to either the X or Y axis and the Z axis. Wrapping is limited to cylindrical stock. A side effect of wrapping is that all arc moves must be converted to linear moves for posting. This conversion is controlled by the Wrap tolerance attribute.
You can wrap any milling feature using 4th-axis wrapping or turn/milling. This example shows a simple Groove feature that is wrapped around the X axis.

Note: The features are not displayed as wrapped, but when you generate toolpaths for a wrapped Setup, the toolpaths are wrapped.
