Radial Toolpath Help

[stevieboy]

Hello All

 

When I do a Finish Radial tool path on a core (elbow shape part)

On the ends of the part I can do a Finish parallel

But the middle of the part is where I'm trying to do a Radial to sweep round the curve of the elbow

The problem I'm having is the Radial is leaving

a Scalloped finish.

Also I would put a picture of the part here. but I don't know how to insert it.

 

Thanks

Inserting a picture, you'll need somewhere to host the picture. Many of us use photobucket.com, free account.

 

Upload you pic there, use the image button under the full reply form and paste in the link of where the pic is stored.

 

On the scallop have you tried bringing your stepover size down and/or if you are using filtering, tighetning up the tolerance?

A radial toolpath will leave a larger scallop on the outer side than the inside of the "elbow". Maybe you could try flowline instead. Or as John stated tighten up the step over a bit.

Thanks for all the advice, Which I'll try soon

I found the problem, and it was my doing.

I had my total tolerance set to .005, I thought it was .0005

Sorry..

" Oh yea.. also I said Scallop, I should have said segmention, The scallop was ok

 

Must have been all that turkey! or

 

Thanks again for all Ya'll help!!

It's just like the spokes in a wheel. The further you are from the center hub, the larger the gap will be at the outside of the wheel. Set the offset to the inside radius of the elbow and make your angular step smaller. Try using a Smooth Gap transition.

Thanks Mike

 

After missing around with a few toolpaths...

I found that Surface Finish Blend worked very nice!

and saved me from creating two other Operations
