CATIA Training Advanced Part Machining

Guidance: Combin Tanto
= Tanto Fan (during leave distance) + Tanto + Tanto Fan (during approach distance)
Tanto guidance definition: (exists alone only as a local mode)
Tool is tangent to the drive surface at a given contact height.
Tool Axis contained in a plane normal to forward direction
Approach and leave distance parameters can be modified

Combin Tanto: This strategy ensures that the tool stays normal to the Part in the forward direction
with a fanning at the beginning and at the end of the tool motion.
This strategy is good for circular and planar drive surfaces where the isoparametric curves are not
proper (incline isopararimetric) to force the tool to have a minimum lead angle.
