5 AXIS packet problem

[mirek1017]

Can some one can check  the 5 axis packet toolpath . my time calculation newer end ,but this is easy 5 axis toolpah 

tap holder.MCAM-CONTENT

Are you trying to cut the Groove (undercut area) section or the slots?

The groove (undercut area) can be cut with a T-Slot/ Woodruff style cutter using a regular Contour Toolpath.

Thank you for reply 

I just wanted to cut grove with this toolpath.I know I can use sloter cutter, but I want to find, why the packet didn't work.

@mirek1017 You made surfaces for walls/floor but your floor surfaces are reversed. That's why it won't regen correctly.

Thank you so much for your help ,it is working now ,bit why is cut all part when I am select only grove and I select containment ?

so I need to have selected stock or just wall and floor  for this toolpath ?

[GIZMO 21]

sometimes mastercam wants to do weird s#@t. i find what I'm looking for and make it work and just go with it.

as long as its a good pc and i don't crash the machine..

Where I cant find this box ?

[GIZMO 21]

 

in collision control tab.

I am use unifed  morph  for simple rad 

 

how I can eliminate this plunging marks on my toolpath ?

 

 

 

 

 

 

 

 

[GIZMO 21]

it looks like the rad on your ballmill is larger than the one on the part. might have to use a smaller dia. ballmill.

Ok thank you .let me try

In cut pattern there is an option to round internal corners. It may help.

For that fillet - Or turn on "round corners" in on the Cut Pattern page.

On the original question of Pocketing.  The thing to keep in mind with Pocketing (and Opti, for that matter) is that they're really Volume Removal Tools.  They need to have either volume, or try to guess the volume to be removed.  Both work better when given stock assuming everything else is equal.

There's a few issues with the original file and I want to explain what why they're happening and why Gizmo's changes work:

The toolpath offsets from the floor to generate the pattern, which is why the Surface Normal needs to be reversed (Surfaces > Normal > Change).

Your containment isn't doing anything because it's not a containment boundary.  It's two independent chains that don't form a single area.  I'm surprised it doesn't error out when generating with that selected.   If you do want to use a containment boundary, then it has to be one contiguous loop.

The toolpath expands to cut the entire stock model that's outside of the containment (yours doesn't count because of the above point).

If you don't have stock, it will try to figure out volume from the wall height.  This works fine as  long as the walls are all the same height, but can cause problems if the heights are different height.   Another way to control this is not to use a containment, but instead make a stock model that is only the area to be removed.

I just  programmed a round part similar to the o.p but it had a little more detail in between 2 flanges with 5 axis pocket rough.

I chained the same way with 2 curves not touching each other, used a stock model that i created from the turning operation to tell it where it had material. it kept the tool from coming outside the 2 curves.

I didn't think it would work but it did.

Neat, that must have been improved then
