Optirough and tilt holder to avoid gouge

[Mikew8190]

Hello, using mastercam 2018 with multi axis. Can I use tilt holder to avoid gouge in the dynamic optirough toolpath? There doesn’t seem to be a way to convert to 5 axis either.

Only on finishing.

 

You can trim to holder 

 

Or triangle mesh can rough spinning c axis

No I will do a few different things as I need to when I need this ability. Multi-Axis roughing it limited to certain shapes, but does do a good job for the correct shape.

To build on this a bit, although technically you COULD use Convert to 5 axis on an opti, but the problem you have is that it won't be controlling whether you tilt into stock that will be removed in the future, i.e., it'll only be tilting to avoid drive & check surfaces, not the material that exists at that particular moment in cut.   That's why it's not enabled like the other Finishing toolpaths.

The big difference is that Multiaxis Roughing (2020 or before, in 2021 it's now the "Multiaxis Pocketing" toolpath with additional capabilities) is always normal to a floor, meaning that it won't support undercuts (in 2020 or before).  Because it's always normal to the floor, you know where all the previous material was removed and there's no surprises about the tool contacting stock.   In 2021, this problem is solved by only allowing undercuts with an offset pattern (not Dynamic), so you always know which way you came from.

If you do want to be successful with Multiaxis Roughing, I highly recommend using stock (so it knows where to remove material) and to make a single floor surface so it will always have a logical direction to be normal to.
