Pocket, limit operation

[GD485]

Hi all,

I’m very new to CAM and CNC and just discovered Kiri:moto and would like to ask a question.

The problem I have is due to how I need to clamp a part to the router table table and the way the pocket function works. The Part I’m machining is a wheel and the stock I’m using is a section of round bar sitting on parallel bars on the machine table. To hold it in place I have 4 radial clamps spaced around the stock circumference. The 3d model has a flange on the outer face that does not extend to the full height.

When using the pocket operation the external circumference surface is sliced which means the end mill would hit the clamps.

The question is it possible to impose a limit to stop the outside face (or any other section) being machined. ( My intention is to turn this face on a lathe using a mandrel as a separate operation).

By the way, Kiri:moto is a great bit of software and a joy to use, far better than the tool path software I purchased for and extortionate price!

Thanks for you time.

Hey there, Thanks for the kind words about Kiri:Moto. Could you please attach your workspace, so that we can reproduce what you’re seeing. You can export with Files→export and attach the `.kmz` file.

the pocket operation allows for selecting individual faces, but there’s currently no way to isolate pocket areas with mathematical limits. Again, It’s hard to say what to do when I can’t see your model.

As a start, I’d recommend looking at the CAM docs page.

I make a dummy part in my CAD to allow for pocket only the spaces I want to pocket.

for example wanting to trim and locate the hole this item only on the end …..I used the roughing operation. The gray part is the dummy part.

What great idea!

Now I feel really dumb for not seeing that as a solution, a bit of lateral thinking on your behalf.
