Moving UCS after tool paths are done?

Hi

 

I'm very new to Featurecam.

 

I have a 4th axis indexing part using 4 setups. I've finished programming everything and about ready to post.

 

Is there an easy way to move a UCS, leave the tool path where it is and re-calculate the job.

 

I decided at the end of programming that I'd rather reference everything from the face and centre of the 4th axis. I already use this point for the 4th axis index, it would just be convenient to move the 4 setups that actually contain the machining operations to the same location just indexed round by 90 degrees each setup.

 

Thanks

It depends on how your post is setup but you should be able to move the first Setup to the location you want as your zero, all other setups can remain where they are and the code should all adjust to the new zero location.

Yes, that should be easy to do.

 

Double click each setup, select Edit, then select "Align to part geometry"

Pick the location of your new setup x/y/z location, and at the very end select "Keep the features in the same location relative to the stock"

 

It will move your setup location and recalculates the existing toolpaths accordingly.

Hi

 

I tried this. The UCS moves just fine I selected the option to leave the tool paths in place relative to the stock. 

 

When I run a simulation, it pretty much has a meltdown. the tool paths gouge all over the place, this looks like it doesn't factor for the new retract height but even when I increase the retract to allow for this, it still starts cutting the stock it finds at the new Z position rather than leaving the toolpath in place.

 

It looks like the Z retract has to be set to double the change in UCS height to clear the part.

 

This is what it should look like for one op,

followed by what happens after moving the UCS,

followed by the same but correcting the gouge from positioning by making a massive adjustment to the retract height.

 

Using Featurecam 2017 on Windows 10 if that helps

 

Does anybody know what I'm doing wrong?

 

Thanks

Hmm

 

 

  Just did it on an 8 sided part to make sure I didn't miss anything ....

Well, I didn't.

The Z-rapid plane is calculated from the extent of the stock, while the retract plane is calculated from the feature.

 

So the only thing I can think of is your post might not output a Retract to Z-rapid plane before indexing.

 

Just for giggles, in your operation settings -> Misc, check if the "Retract to plunge clearance" is ticked in.

If it is, then quite possibly that is your problem as the tool does not retract to the rapid plane between ops.

Hi

 

Tried again today and if I do a small change, it seems to be ok, it just loses the plot trying a larger move.

 

I managed to move the 2 setups on the long sides of the part so not quite what I set out to do but good enough.

 

Thanks for the help.
