Vcarve inlay

[freddeifk]

I just made a cuttingboard With a inlay,
And that was my first inlay With a v bit.

And i use the same settings as in the pdf documentations for vcarve inlay.

Pocket flat depht =down in the wood 0.3(7.5 mm)

Inlay flat depht= 0.2(5 mm)
Inlay start depht = 0.2 (5 mm)

And it was working ok,

But i was nearly too much that My machine could handle a so Deep start depht, it went down in the wood 6.5 mm in one pass,
I normalt wont Take moore then 1.5 mm in one pass.
What settings are good for mee too use ?
I have Xcarve from inventables

Go into your tool database and set the Pass Depth to 1.5mm

[freddeifk]

Yes,thats what i am doing, but the first pass its going down in the wood the whole start depht 5 mm + 1.5 mm
And after the first pass is Done , its going down 1.5 mm as i set the pass depht

If you tell it to start at 5mm down that's where it's going to go. It assumes there's no material there, carving in the bottom of a pocket for example.

Can you post a screenshot of the toolpath you're using and the tool?

[freddeifk]

ok,
But then i really dont need too set the start depht,

i can set the full depht too 10 mm a 1.5 mm pass (and start depht 0) ?

and it will bee the same as start depht ?

No that won't give you the same results because of the v bit angle

[highpockets]

Yes, set the start depth to 0!!! If you set the start depth to anything other than 0 the machine will plunge to that depth before starting your cut. This I believe is what's causing your troubles.

John, I don't really do inlay work but surely setting the start depth to zero will make the pocket to small because of the angle on the v bit.

Hey Martin,

my point was that setting the start depth to anything positive value greater than 0 will be telling the machine the immediately plunge to that depth then start using the toolpath information. The OP was setting the start depth to 5mm + 1.5mm cut depth and it's too much for his machine. By setting the start depth to 0 then setting the cut depth to 6.5mm he can control the depth of cut per pass better.

Sorry if I didn't make that clear in my post.

OK, Martin showed me the error of my thinking. I was thinking about the female pocket not the male inlay. You can't set the start depth to zero and double the finish depth to create the male inlay. Not exactly sure why, but it doesn't work.

Using a clearance tool to clear out most of the material may help.

Sorry to miss lead.

Yep, Martin is right....the Male won't seat deep enough...I spaced start depth on a Zebra while I was programming on the fly with Dad asking questions a mile a minute over my shoulder....machining waste I lost some stripes...and finish sanding I lot more
OP may want to reduce plunge speed/feeds/stepover to produce smallest chip that keeps the bit at room temp or slightly warm to touch...plunge speed mainly.

oops.. forgot pics...Zebra 1 where start depth was zero is on right...the further down I went..the worse it got:(
