10.4.9 Open groove (CYCLE899)
Function
Use the "Open slot" function if you want to machine open slots.
For roughing, you can choose between the following machining strategies, depending on your
workpiece and machine properties.
● Vortex milling
● Plunge cutting
The following machining types are available to completely machine the slot:
● Roughing
● Rough-finishing
● Finishing
● Base finishing
● Edge finishing
● Chamfering
Vortex milling
Particularly where hardened materials are concerned, this process is used for roughing and
contour machining using coated VHM milling cutters.
Vortex milling is the preferred technique for HSC roughing, as it ensures that the tool is never
completely inserted. This means that the set overlap is precisely maintained.
