Blisks

The Blisks category on the Strategy Selector dialog contains the area clearance and finishing strategies required to machine a blisk or impeller.

Note: Blisk strategies are only available in PowerMill Ultimate.

The blisk strategies are:

• Blade Finishing finish machines the blades.
• Blisk Area Clearance rapidly removes material on a blisk or impeller.
• Hub Finishing finish machines the hub.
• Single Blade Finishing finish machines single blades.

Note: You must define the geometry that makes up the individual components of the blisk or impeller before you create a blisk strategy. Each component must be grouped into a single Level or Set.

Blisk machining strategies work only with:

• Spherical tools (ball nosed, tapered-spherical, and spherical-tipped disc tools).
• A cylindrical symmetric and untrimmed hub.
• A cylindrical symmetric and untrimmed shroud that must match the blade (and splitter) profile.
• At least 2 blades.
• If there is a splitter blade, it must extend as far radially as the left and right blade.
• The fillet must be in the same level (or set) as the blade.

The common tabs are described in common toolpath strategy pages.
