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.

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