Program Turbine Blades and Mill Them Reliably and Effectively

The Blade package

5-axis CAM software: The Blade package from OPEN MIND provides optimized milling strategies for complete machining.

The Blade package provides automation features to generate simple machining definitions and incredibly short programming times. This includes the rolling ball function for milling transition radii, the best fit function for automatically setting the optimal start position for the finishing cycle and the automatic lead angle correction function for collision avoidance of the tool face with concave surfaces.

5-axis Machining: Turbine Blade

This video shows a machining example of a turbine blade programmed with hyperMILL.

5-axis Machining: Aluminium Turbine Blade

This video shows the machining process of an aluminum single blade that has been programmed with hyperMILL. The final blade geometry was made segmentally using barrel cutters. This ensures high blade stability when roughing and finishing.

5-axis Machining: Blade Segment Example

This video shows a blade segment made of NAK80 machined on a Mazak Variaxis C-600. For finishing barrel cutters and hyperMILL MAXX Machining strategies have been used to save machining times.

Turbine blade milling – Complete from top to bottom

3d arbitrary stock roughing

3D arbitrary stock roughing 

On the basis of freely definable stock, blades are machined from various directions.

top milling

5-axis blade top milling 

This strategy is used for finishing blade surfaces. It is possible to generate spiral toolpaths as either 5-axis or 4-axis simultaneous machining operations using ball-end or bull-nose cutting tools.


swarf cutting

5-axis blade swarf cutting 

This strategy is used for the machining of platform surfaces. Swarf cutting can also be used to machine the transitions between the blade and the platform surfaces that cannot be machined using 5-axis Top Milling.

fillet milling

5-axis blade fillet milling 

This function optimizes finishing at the transition between the blade and the platform surfaces at the tip or root.


additional cycles platform machining

Additional cycles for platform machining 

A series of 2.5D and 3D strategies are available for machining the blade platform and root sections.
