Larger Area Clearance Tool

Post by freddeifk »

Right now i am making some VCarve inlays, and i use the option
"Larger Area Clearance Tool" to remove material a bit faster ,

I have the inlays set at deep 0.2 inch (5 mm)

and use the 1/8 endmill set at 0.06 (1.5 mm) each step ,

but when i use this option with "Larger Area Clearance Tool",
the 1/8 end mill goes in the whole deep at once 0.2 inch (5 mm ),

it works , but it seems a bit to much to take 0.2 inch at once with a 1/8 end mill.

is there a solution for my problem ?(i wants the bit to be as regular , to do the setting i made in the toolsetup )

If you have the 1/8 tool set to only .06 each pass, then THAT what it should be doing. Take a screenshot of the 1/8 tool settings. It seems like something is not set properly if it is digging down to .2.

Are you sure you're not mixing up pass depth with stepover in the tool settings?

Which version of VCarve are you running?

I Have an older version of VCarve pro 9.5,

i read in another post that its so ""Larger Area Clearance Tool" works ,
'that its not going to set pass depht ,

to make it work that way i have to set Roughing pass or something,
and that should be in the same place where i set ""Larger Area Clearance Tool"",

i have to check this when i come home, i dont remember i have seen this option in my Version.

I've tried multiple scenarios with that version and I can't replicate what you're seeing. Could you attach a VCarve file that shows this behaviour?

I think you might be getting mixed up with toolpaths with the other threads. Roughing toolpaths are for 3D work not for pockets. The 3D finish toolpath does everything in one pass which is probably what you've read but it doesn't apply to a pocket toolpath.

Also the way clearance tools are set in the toolpaths are very different in later versions.

Adrian: note that the poster is doing “VCarve inlays” that is tapered inlays, that is Zank inlays. So the toolpath in question might be the V-Carve / Engraving toolpath (of course it could be the Pocket toolpath if he is “dong things wrong”).

Thus the 1/8 inch bit is going to full depth because the start depth is going to be quite deep and the flat depth within the pass depth of the cut.

There is no Larger Area Clearance tool option in VCarve 9.5 unless he's got his terminology mixed up again and means the Flat Area Clearance tool option.

I expect you're right though as the start depth used in that scenario would account for it.

In v9.5 the Pocket toolpath calls it LAC but the V-Carve toolpath calls it FAC.

Only a file or screenshot will settle whether it’s a Pocket or V-Carve toolpath.

Sorry for giving you some wrong information,

I am in VCarve and my question is about "Flat area clearance tool " sorry for writing Larger area clearance tool .

So if i use this option ,i cant use pass depht for the end mill ?

or am i doing things wrong ?

except of that , the Vcarve inlays become great :D

Ok,
Now i think i understdand,
I set the startdepht to 4.2 mm and the flat depht to 0.8 mm,

And then the endmill goes down 4.2 mm ,

Do i have any option to use the endmill without to use a startdepht ?
And only use the vbit with startdepht?

Not natively, the whole idea of the start depth is for carving on bottoms of pockets etc. The software is not expecting there to be any material there so it starts all the calculations from that depth.

There are gadgets that enable multi-passes to overcome the issue for that type of inlay though - viewtopic.php?f=51&t=38767

If you are running VCarve Desktop and therefore don't have the ability to install the gadget that Adrian linked to I detail a manual method for accomplishing the same thing at this post. You might also want to scroll up to the previous post at that link for a bit of background for the whole tapered inlay process.
