How would I define the Freud 72-300 bit for Litho?
This freud 72-300 bit is a conical (V shaped) shaped ballnose with the tip being 1/32 inch.
I want to try it for lithophane.
How woud I classify this bit as an addition to the bit menu. Its not exactly a straight ballnose, and it is not a V bit either.
Its a bit of both.
Here it is:

Enter it as a tapered ballnose

I agree, tapered ballnose.
In fact a 1/32 TB is what I use for lithos, takes some time to get the fine detail but I can get details down to individual stands of hair.
Geometry of your particular bit could possibly cause variations in the cut vs a standard ballnose, only real way to tell is use both and see what is different.

I don't see any entries for a tapered ballnose.
Only Ballnose, V bits and Engraving bits.

There isn't a tapered ballnose option for PhotoVCarve. Only the more recent programs like Cut2D, VCarve and Aspire have that option.
I'd try it as a 1/32" straight ballnose as only the tip is really used so the taper should have a minimal effect.

I was going to try and import the PhotoVCarve file into VCarve desktop 8.5 but I do not see an option for tapered ballnose in the VCarve program.

It's definitely there in VCarve. Click New in the database and you can select it before entering the tool info.

You have to change it in the drop down menu on the right side of the Tool Database.kristenanne77 wrote:I was going to try and import the PhotoVCarve file into VCarve desktop 8.5 but I do not see an option for tapered ballnose in the VCarve program.

You could just draw your own. The Freud website has detailed drawings of their bit profiles.

Thanks. I have added the tapered ballnose.
Unfortunately, when I imported the PhotoVCarve toolpath file into VCarve, I was unable to change the bit size that I originally used with PhotoVcarve to the new tapered ballnose bit entry in VCarve.

I never tried it as I do not own PhotoVCarve, but it makes sense to me: you import a toolpath calculated by another software, so you can't change such a fundamental parameter as the tool which requires recalculating the toolpath.kristenanne77 wrote:Unfortunately, when I imported the PhotoVCarve toolpath file into VCarve, I was unable to change the bit size that I originally used with PhotoVcarve to the new tapered ballnose bit entry in VCarve.
I assume you have the same limitations as in Aspire: moving the toolpath (and not resizing it) and changing cutting parameters (speed and feedrate). See your Vcarve reference manual or help.

In PhotoVCarve, I will try creating a new "engraving bit" with a diameter of .25 inch, side angle 0f 6.2 deg, and a flat diameter of 1/32 (.03125). That should be close.

If you want to be better than just close you could use a flat length of 0.0280". Trigonometry comes to the rescue.kristenanne77 wrote:In PhotoVCarve, I will try creating a new "engraving bit" with a diameter of .25 inch, side angle 0f 6.2 deg, and a flat diameter of 1/32 (.03125).
