Hybrid Rib roughing parameters

The Hybrid Rib roughing strategy is designed to machine very thin walls.

For this operation, the Roughing/Finishing tab displays the parameters that enable you to machine each Z-level with roughing and finishing passes, after which machining of a lower level is performed.

Roughing

This section enables you to control roughing passes and levels performed against a rib.

• Stepover

This parameter defines the distance between two parallel tool path passes.

• Restrict offset

When the Restrict offset option is selected, you can limit the number of parallel passes by specifying the value in the Number of offsets field.

• Number of offsets

This parameter enables you to define the number of roughing offsets required at each level.

• Boundary pass

When this option is selected, an additional pass is performed around the outside perimeter of the constraint boundary on each roughing level.

• Offset

This parameter enables you to define an offset applied to the constraint boundaries from outside.

Finishing

This section enables you to control finishing passes and levels performed against a rib.

• Number of levels

This parameter enables you to define the number of finishing levels required between step downs.

• Number of offsets

This parameter enables you to define the number of finishing offsets required at each level.

• Stepover

This parameter defines the distance between two parallel finishing passes.

• Order

This parameter enables you to control the order of linking the finishing passes. The following options are available:

During, upwards: after each roughing level, the finishing levels are machined from lowest to highest
During, downwards: after each roughing level, the finishing levels are machined from highest to lowest
After, upwards: all roughing levels are machined first, followed by the finishing levels from lowest to highest
After, downwards: all roughing levels are machined first, followed by the finishing levels from highest to lowest.
