Re: Is it possible to nest parts / bodies for milling?

Isn't this what "copy", "array" and "simple copy" are for?

Re: Recent change to movement with safe and clearance height

Thanks for explaining this chrisb!
I have seen the picture with the definitions many times before over the years, but it was not until your example above that i finally got what safe and clearance is for. To me, they are just synonyms, hence difficult to understand.

Re: inappropriate cutting speed on ramps.

Helical paths are the obvious exception to existing tools not doing simultaneous x,y,z movement, are there others I'm missing. I can think of holding tags, slots, pockets, profiles etc with ramp or zigzag entry and anything 3D. I think there was a discussion on this topic as well and think the conc...

Re: Align top with bottom

Thanks for reaching out, Chris! I would say that this issue exists regardless of the model, but the solutions may vary. A part milled from a rectangular piece of stock is one case. Cylindrical stock is another. Some parts can be held directly in a vise or chuck, others may need a fixture. Milling th...

Align top with bottom

Hello forum, When milling a not too complex part, I am thinking it would be natural to mill the top first, then flip it over and do the bottom and then be done. For this to work, the system needs to be touched off on the flipped part somewhere, but where? At this point, the unfinished stock is expos...

Overshooting the boundary is equally important here, as in face milling. Just don't overshoot into the material! :o

Re: Adaptive Path/CAM Operation

There definitely are. Not all tools are even able to plunge, like a face mill for instance. There is nothing in the center that can cut. Also of interest here is to have the cutting area overshoot the outer boundaries. Hard to explain, but imagine you were cutting this by hand. Then you would not on...

Re: Flycutter Facing

It is not a bug - just missing functionality. For now, we have to accept it. I think I have seen a feature request for that or something similar. If redefining the stock is not a good solution for you, you could create a helper object instead. In this case, just a slab with the necessary width to le...
