The ModuleWorks MultiBlade component is specifically designed for the fast and easier programming of impellers and bladed disk components and includes multiple strategies to efficiently rough and finish each part of these complex shapes
The machining of impellers and other rotary bladed parts requires some fairly heavyweight 5-Axis machining technology. The standard 5-Axis component can be used to machine Multi-blade parts. However, achieving optimal results can be a lengthy and complex process, especially for new users given the geometry and toolpaths involved. Many different parameters for gouge protection, tool axis control and others need to be manually specified and many iterations may be required to produce good results.
MultiBlade changes this with a design specifically targeting the machining of these components. The user interface uses standard impeller and blade terminology and the workflow is designed to take the user step by step through the process of roughing and finishing toolpath generation.
MachiningThere are four main machining strategies offered by MultiBlade. These are blade roughing and finishing along with blade hub and fillet finishing. Industry standard terminology (hub, blade, leading edge, trailing edge, fillets, splitter and shroud) is used throughout to guide the user though each stage of the programming process.
Any bullnose, ballnose or flat endmill tool type may be used for machining. Typically tapered tools are used as these allow better access to complex undercut geometry that is usually a feature of bladed components. Barrel mill cutters are also supported; their unique shape can provide better surface finish and shorter machining times. Take a look at the video below. It shows how our partner SolidCAM has utilized MultiBalde within their CAM solution.
In part 2, we'll be taking a more in depth look at how a blade is programed with MultiBlade.
