help for leg

[kevin]

Learning the limts
I figured out what you said but I cant figured out how to taper the flutes in virtual tool

I have turned any thing yet just a sample and air cuts

Or I might give up and ask you I'll see how Iam at the end of the day

Thank

Kevin,

The Indexer Virtual Tool uses the shape of the bit to cut flutes, etc, and can cut them along a taper, but they will have the same shape...the profile of the bit... along their entire length.

If I'm understanding correctly, though, you want the flutes themselves to taper...to be narrower at the small end of the taper than at the large end. I don't know of any way to do that with a single bit without modeling the flute in something like Aspire or ArtCAM, so that it's cut as sort of a tapering pocket?

Just as an FYI, a newer version of the Indexer Virtual Tool than Jack posted is installed when you install the ShopBot software. It's in the "Tools" menu.

Your right Bill, I did some posts a while ago where the flutes them selves were tapered, I tried a few ways of doing it without involving artcam, but in the end I cut them as 3D models.

[kevin]

Steven I.am having customers walking in
Its hard to learn
i would like that leg done in art cam can you do it for e-mai price it doesn't have to exact but if its a model I would lave a little more flair on top

[steve]

Yea, I could do it. How far do you want me to take it? do you want just an artcam model or toolpaths and all? Do you have a vector of the leg?

[kevin]

I have no vector just the picture .It desnt have to be exact 36 inch long 4 inch wide .Quarter inch ball nose for all i/8 at a time wood is cherry shoulker 6.5

Its important client I think learinng on the job might look rough

Toolpath and ARTCAM

i.AM BACK NOW

[kevin]

I forgot i have the same setup as you except 6 inch z

[steve]

OK, I'll see what I can come up with.

[oddcoach]

i have used Excel to create tool paths for tapers. If the taper is straight and yours looks like it is.
all you need are the starting and ending points for the taper and the diameters of the leg. divide the number of flutes by 360 this will tell you how many degrees to rotate the b axis for each one.

if you use Excel you can have it do the math for you. the copy and paste the values of the cells(use paste special) to a new worksheet. if you do not the formulas are what are in the cells and it won't work. then save the file as a CSV. then just rename the file from .csv to .sbp. then you can put the SA MS and end statements in with the ShopBot editor
hope this helps

Here is what I have, it was cut with a1/16" bit in the simulation, the flutes were done with a .25" ball nose.
Want any changes?

Oh yea, keep in mind that in the simulation the top square part look round.
