» Topic: Wrapping Group: 3D surface
- April 8, 2014 at 11:37 pm #17675
Just getting to know more on how to use the wrapping group. I’ve seen lots of video and tutorials on doing 2d wrapping on a cylinder. I do see that it allows for 3D toolpath in wrapping group, assuming I select 3D surfaces that is unwrap, but I can’t seem to find a tutorial or whether that is possible. bodcad does allow 3D tool path creation but I haven’t seen a sample.
If anybody has info or what not about 3D toolpaths on a wrapping group, I’m all ears.

This is correct, you can define a wrapping group and use a 3D tool path. There are no specific tutorials that cover this however. To do this, you would draw the surface unwrapped and then use the 3D Tool path that best suits the requirements of the surface that you are cutting.April 14, 2014 at 6:34 pm #17742
I drew a surface unwrapped given the knowns-My arc length and cross-section-an extrusion basically. But when I did a 3D tool path, the toolpath is only generated to the limit of the round stock size and doesn’t cover the entire 3D surface limits. I do know that my 3D length is greater than the diameter of the cylinder where it to be cut on. I’m trying to cut this test groove with a certain cross-section that goes at an angle to the axis of the cylinder. I wish it was a simple groove. Then I would just use a 2D line instead, do a wrapping group and pick the right cutter.
Should I change the stock size and fool the software but wrapping in the actual cutting stock? I did an advanced rough in my approach which is controlled by the stock. I’ll keep fiddling with this.April 14, 2014 at 10:45 pm #17743
In the advanced rough feature there is a page that limits the area in which the tool path calculates. This area is on the parameters page. You can set it from Min/Max All to Min/Max Machining Surfaces to take the stock out of the equation.April 15, 2014 at 11:51 pm #17758
Thanks for the hint. I’ll give it a go. If things don’t turn up, then I’ll be back.
