Hi Guys,
I’m having problems generating this image. The model portion looks good, the 3-D rough toolpath seems fine but the finish toolpath loses the level of detail I was trying to obtain. The finish toolpath does not gives you too many options and I tried generating unsuccessfully with a smaller bit. If you could take a look at it and suggest something to get around this issue I would appreciate it.
Thanks, John.
Bee V1.c2d (3.5 MB)
Not seeing any 3D model or 3D components in this file. 3D Rough & Finish paths need 3D surfaces from heighmaps or STL’s.
2D vectors can be used to create 3D components, but it does not happen automatically.
Could it be a v8 file opened in v7 (or vice-versa)?
Tried it in both, not seeing any 3D components in either.
Sorry for not explaining myself very well. I will try to explain what I did and what is occurring.
Design
I start off in design to create my image (Bee). Inside the Bees wing are small irregular circles.
Model
I create the stock of 19 mm thick.
I then select the Outline of the Bee and lower it -11mm into the stock.
I then select the Outline of the Bee and raise it +3 round.
I then select the irregular circles Inside the wings and the rectangles inside the tail and raise +3 rounded.
Show 3D
It looks good at this point.
Toolpath
I then select 3D-rough and 3D-finish. When I the
Select simulator I do not see this detail inside the wing (irregular circles) . I am not sure how to go about generate these irregular circles. Thanks John
Alright, so I loaded your file again & setup some components close to what you describe in the 3D modeling. Noticed that your file is set to Standard Model resolution in the project setup - you should definitely change that to Very High instead for such a small object.
Then have a look at the 3D toolpaths.
Which definitely should not look so ragged. A look at the specified tools & I see the 3D Roughing is using a 1/16 Endmill & the 3D Finish is a 1/8" Endmill - so that’s kinda backwards.
I would use a 1/4" Endmill or Ballmill for 3D Roughing & the 1/16" Endmill for the 3D Finish.
Changing that up:
Which brings out much more detail.
The 3D model looks like:
Adjusting the Stock Setup:
We then adjust the model to make things clearer:
You’re using a very small tool for roughing — I’d suggest a #101 instead:
Then, if using a smaller tool with a cutting edge inset from the shank, inset to keep the tool shaft from rubbing against the uncut area:
Then, instead of #102 DEFAULT I’d suggest using a #111:
which previews as:
If desired, adjust the stepover:
and if desired, add another 3D Finishing toolpath:
It may help to review:
I made the changes you suggested, and it looks much better. I will start milling and hopefully get the same results. As aways thanks for your continuous support. John
Note that when using smaller tooling one needs to be careful of vertical features that they are not taller than the cutting flute length.
