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 or the automatic lead angle correction function for collision avoidance of the tool face with concave surfaces.

On the basis of freely definable stock, blades are machined from various directions.
This strategy is for finishing blade surfaces. It is possible to generate spiral tool paths as either 5-axis or 4-axis simultaneous machining operations using ball-end or bull-nose cutting tools.
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.
This function optimises finishing at the transition between the blade and the platform surfaces at the tip or root.
A series of 2.5D and 3D strategies are available for machining the blade platform and root sections.
This video shows a machining example of a turbine blade on a GROB G550 machine programmed with hyperMILL®.
This video shows the machining process of an aluminum single blade made on a Grob G352 using Mitsubishi cutting tools and has been programmed with hyperMILL®. The final blade geometry was made segmentally using barrel cutters. This ensures high blade stability when roughing and finishing. For efficient root machining hyperMILL® offers proven CAM strategies from 2.5D to 5-axis.
