Water-Line Tool Path with BCC

[Kiwi]

I have a part with tapered sides (draft) which I wish to machine with a water-line tool path.
Can this be done with BCC Ver20.7 and how?
Any hints would be appreciated.

With 20.7 the closest thing might be the "spiral' path. My expeience with trying to machine drafted walls with it is that it will move up/down in z as it goes around. This leaves a mark in your finish evey time it does this. I never figured out how to get around this, and usually just resorted to radial path, though not as effecient it was consistent on finish.

Kiwi,

I have been doing this for a little while before buying V2007. Try the Tapered Pocket Function, or make a Solid and Slice it into sections then Extract Lines & Arcs to make Pockets. Then use the Pocket Function to Water Line Rough your Part. Finishing will be very time consuming.

That is why I bought V2007, too much work in V20 and V21.

Thanks spock and Toby.
I was relying on you Toby to have a workable solution.
As the taper is not important on this job , more an appearance thing, I created a number of offsets which gave me profile lines which I added a Z. Picture attached.
If I'm unhappy with my toolpaths I will give your method a try.

Kiwi buddy,

Why not take it easy on yourself and buy a Tapered Bull End Mill? Use a regular Rougher first then the Tapered Bull Mill in Depths of Cut to the final Depth.

As you say this is for looks not function.

BTW It looks almost like a Motorcycle Handlebar Mid Section Joint for the Forks, is it??

Cheers!!!!!!!

I don't look for an easy way, only a better way.
Yes, machining a pair of triple clamps for a motorcycle.
I'm satisfied with my toolpaths, the finish has pronounced cusps but this gives a neat look.
Thanks confirming BCC V20.7 dosen't have a waterline feature, I thought it was me not reading the manual properly.
Sounds like V2007 is a much better version.
Cheers
