The ATM method supports up to three splitter blades, provided that the following criteria are met:
The leading edges of the main and splitter blades are both rounded.
The trailing edges of the main and splitter blades are both rounded or both cut-off.
The leading edge of the main blade is positioned, in the meridional direction, significantly ahead of the leading edge(s) of the splitter blade(s).
The trailing edges of the main and splitter blades, if cut-off, are at the same meridional position.
Considering the specified direction of theta, the main blade is in the lowest theta position and the shortest-meridional-length splitter blade is in the highest theta position. You can specify the theta direction in the Machine Data object. For details, see Rotation.
