3D MILLING
The 3D_Milling_1_IV.prz example illustrates the use of InventorCAM 3D
Milling for the machining of the mold core shown above.
The following InventorCAM operations are created to perform the machining:
• Roughing (3DR_target)
This operation removes the bulk of material using the Contour
roughing strategy. An end mill of Ø20 is used. The machining
is performed at the constant-Z levels defined, using the Step
down value of 5 mm. A machining allowance of 0.5 mm remain
unmachined for further finish operations.
• Rest material machining (3DR_target)
This operation performs the rest material machining of the areas
that were inaccessible to the tool in the previous operation. An
end mill tool of smaller diameter (Ø16) is used. The Contour
roughing strategy is utilized in combination with the Rest
material mode of the Working area definition in order to
obtain optimal and effective tool path removing the cusps left
after the previous operation. A machining allowance of 0.5 mm
remains unmachined for further finish operations.
