3D MILLING
20
The 3D_Milling_2_IV.prz example illustrates the use of InventorCAM 3D
Milling for prismatic part machining.
The following InventorCAM operations are created to perform the machining:
• Roughing (3DR_target)
These operations remove the bulk of material using the Contour
roughing strategy. An end mill of Ø14 is used. The Open Pocket
machining is used to perform the approach movement from an
automatically calculated point outside of the material. The tool
descends to the necessary depth outside of the material and then
moves horizontally into the material. A machining allowance of
0.2 mm remain unmachined on floor and wall faces for further
finish operations.
• Rest material machining (3DR_target; 3DR_target)
At this stage the rest material machining is performed for the
corner areas, that were inaccessible by the tool in the previous
operation. The machining is performed in two operations using
end mills of Ø8 and Ø5, in order to minimize the tool load. The
Contour roughing strategy is utilized in combination with the
Cut only in Rest material option in order to obtain optimal
tool path A machining allowance of 0.2 mm remain unmachined
on the floor and wall faces for further finish operations.
