Dynamic Milling with open pocket

[Justin Beebe at Folsom Tool]

Is there a way to get 2D Highspeed Dynamic milling motion on an open pocket. I want the tool to start outside the material and work it's way in like the old 2D open pocket method but I want to use a dynamic cutting motion. In the picture below I need to remove material inside the red geometry. The green geometry is my stock. I would like the tool to plunge off the material and works it's way in.

Heres how I do it

Thanks JParis that looks awesome. I got something similar working. I chained the two vertical red lines and used Peelmill. By adjusting the start and end points of the lines I got a path that looks pretty good. I like your method better. Thanks for the help.

Just be aware there are some geometry shapes that will just no work, it cuts outside instead of inside. When I encounter those, I use Dynamic Area but I build and entry area off of my geometry and create an entry point and set my helix to 90 degrees

You can also use "Multiple machining regions" and set an avoidance region.

[JayM]

If you have solids, draw it as a model, pick the floor of the open pocket as the Machining Region and the top surface of the part as the avoidance region.

[Justin Beebe at Folsom Tool]

Thanks for the other suggestions we have solids so I will look into that.

Dynamic Core with avoidance regions.

Give this a try... I think this is new to X7 but I use it all the time first chain is the red lines and second is the green, Using peel mill.

You can add an approach and end results should look something like this

[xycnc]

check this out it shows many other ways to chain other shapes too.

Very slick. Peel mill is my favorite HSM strategy for 2d roughing. It seems to produce much more predictable results and a higher level of control that the other HSM 2d strategies. I have never seen or Imagined chaining examples like that for this tool path. Are these chaining strategies unique to X7?

[Chris Rizzo]

Actually the dynamic chaining in x5 was a bit of a brain teaser. In X6 they introduced the whole machining/avoidance region ndialog. I'd stick to Dynamic core for outside-in situations, dynamic area for closed pockets and features, dynamic rest, and dynamic contour. Anything with the word Dynamic. Peel is much improved for x7, I generally only use it for slot situations. Also the filter settings are you best friend for everything.

Thanks for sharing xycnc, I did not find that method of chaining mentioned in the manual.

[K2csq7]

xycnc, that is some slick chaining!

[brandon b]

Pretty sure this is new in x7. Couldn't replicate this in x6 .

[xycnc]

No problem. Just glad I could actually contribute for a change.

[Glenn Bouman]

That Peel Mill method is a neat way to handle those shapes without having to create an avoidance region which is required by Dynamic Core Mill.

I like the fact that Peel Mill has a finish pass option, BUT that chaining method does not handle the finish pass properly

 

Hopefully the finish pass option will be added Dynamic Core Mill.

It's going to get easier, stay tuned...

xycnc, that is some slick chaining!

+1 very neat

 

David - come on, spill the beans

[Masterminder408]

that is some amazing stuff "xycnc" thumb UP

Here are a couple Youtube of some stuff I did the other day.

 

 

 

Both of the videos were shot on a Fadal Mill. We can't use Highspeed toolpaths on our machine is something I hear a lot. You cannot use those toolpaths in the real world. This was real cut and not a CGI thing I got a hot chip on my arm standing 10 feet away from the machine.

[Hertz]

You can use these paths on any machine. All it means when they say "you can't" is the accuracy will not be there. That is why we have finish toolpaths. Nice work Crazy.

Hi Crazy,

What is your deep of cut and step over also filter setting ?

thanks

[DODGERFAN]

Hi Crazy,

What is your deep of cut and step over also filter setting ?

thanks

I'll bet it's 1" deep with 15% step over. Just a hunch.........

 

Cool stuff Ron.
