filtering?

[specprogrammer]

Ok, my understanding of filtering is.... instead of cutting a curve point to point to point, it throws in a go3 and keeps the toolpath smooth. So how come my code has no go3? my machine is stuttering trying to process a million lines of code that should be a few simple go3s. I'm using surf/fin/constant scallop. Filter tolerance settings are as follows. filter ratio 2:1 filter tolerance .00013 cut tolerance .00007 total tolerance .0002 one way filtering, arcs in xy, xz,and yz checked. min arc rad .001 and max arc rad 100. If I open up these tolerances, will it then be smooth? Will the part shape still be accurate?

As I understand it depends on the toolpath and the post. If the calculated arc will lie in G17, G18 or G19 plane it will be posted provided the post supports XY, YZ and XZ Arcs. If the post supports helical arcs they too will be used. If the calculated arc does not meet the conditions of the post, then you still get linearized output.

I usually have go3s present in other programs so I imagine my post supports that.

What kind of Machine and post are you running

The constant scallop toolpath rarely has moves in the allowable planes G17 G18 G19. So that is why no G02 Or G03 moves you may fing a few if lucky.

If you open your filter tolerance, your code will look similar, however smaller. The part will have striations/gouges as a result of a "looser code"... depending on the size of your part and desired finish, it's up to you.
