» Topic: Limit Cutting Air
- June 6, 2014 at 2:21 pm #18524
I have V26(Mill Pro) now, and wondering if the amount of air cutting can be limited when doing a profile roughing pass.
If you look at my file you can see where X and Y starts.

Ummm, how about a zip file?

Why are you doing “91″ passes ???????????
That could very well have a little to do with it.
You also have a contour drawn so it will cut only one direction.June 6, 2014 at 7:32 pm #18530
91 passes breaks down to about a .015 cut.It is a 2″ tube with angles cut on each end, that i only want to cut conventional not climb mill.June 6, 2014 at 8:02 pm #18531
I don’t know what to say.I am a machinist,and this is a simple part that should be 2 saw cuts,and then a clean-up pass (1) with an End Mill.Climb cut at that.You have over 3 hours cut time to do what should be a 10 minute job.Sorry,not trying to be a dick,but I am at a lost here.June 6, 2014 at 8:07 pm #18532
Not everyone has ALL the tools to do such. If i had a cold cut saw i would be done This is a “hobby” at home, but i have been in the machinist trade for 20 years. And the mill iam using is a light duty mill/drill. Also this more of an example in trying to find a way to reduce air cutting time.

See if this helps,,,change your feed and rapid plane to -2.050
Change your lead in and lead outs to circular.

Hmm… That shaved off some time. But seems like there needs to be a way of maybe a boundry. As you can see that the toolpath starts at full length of cut(all air) when starting to cut off corner, when really should only start at a little more than the cutter radius or diameter.
You got me thinking, (can be dangerous;) i tried doing a Plunge Rough and this looks much better. I simply made a pocket that is cutter diameter longer and just wide enough for the feature to generate a toolpath. It makes a toolpath with 2 rows of plunge moves. Guess i can manually edit Gcode and reduce to just one row of plunge moves. But would be nice if side roughing feature had some more options so one could limit such air cutting.June 6, 2014 at 10:19 pm #18538
Plunge rough,tubing,small mill,,,,probably not for you,,,Plunge Rough tool path will remove material faster than any other,BUT,it IMO should only be used with aluminum,with a 1 to 1 1/2 inch inserted drill,and a rigid mill with a rigid set-up and some Horse Power.
Now that I am getting an idea of what this “exercise” is about I think I can offer better ideas.I gotta do some other stuff for a while,but in the meantime play with pocketing/advanced rough.That should be the one you seek.Let me know if you need help later.June 6, 2014 at 11:31 pm #18539
here is a sample,,,there is much more that can be done with this.Being a machinist,you will like BoB once you start learning more.

Thats nice I have gotten used to using the Adaptive Roughing option that i never checked out the Advance Pocket.
Its something, i have been using Bobcad sense V14, and V26 is by far the best upgrade i have seen. I have only had V26 for a couple weeks now.
