Correct origin placement on Okuma 800VH 5 axis machine

[?Mark]

This machine is a little different and we're trying to figure out the best programming approach.

Where would you place your origin?

I'm thinking the center of C axis for sure, but Z is a little more flexible. I'm suggesting top of the pallet.

 

What are your thoughts on this?

 

TIA!

I'm suggesting top of the pallet.

 

Looks about right to me.

[?Mark]

Thanks Matthew

 

Anyone else wants to get their vote in before we close this poll?

centered on C and part locating surface wherever that may be.

[?Mark]

Pete, that's what we do for all HMC and VMC with rotary, but with this one I'm hoping to go off the same point and use TCP for minor adjustments?

[Mr. M]

Center and top of pallet gets my vote

[Greg Williams]

If you have TCP (G169) then anywhere is good. If not then the top and centre of the table

Hi Mark

Same layout as our head/table machines in here.

Since the machines that we have also have turning ability I usualy always set the XY origin at the center of the C-axis (there are exceptions though).

Z origin is dictated by the blueprint datums of the part I am programming. It may be locating surface of the part or any other datum on the part that other dimensions must be good to. I never program to the pallet. BTW, I also use TCP as well as G68 to make the programs.

I recommend installing an adapter plate with ball locks for quick fixture changes (not sure how that would work with tombstones though).

The 1st shot is assembly from a couple of years ago.

The 2nd shot is from Vericut (using right angle head) which I suggest you seriously consider if you do not have it yet.

M, Greg and Rob, Thanks for your input. Looks like we're all on the same page (center of C with Z at table or datum). I wanted to make sure we didn't miss anything here and started down the "dark path"...

 

Rob, we're going with an adapter plate and a Hilma quick change grid system with vises and the Vericut is coming soon after.

Looks like the housing around your spindle is similar to ours. Does it cause you trouble when it comes to reach? Do you use extended toolholders? Big plus?

 

TIA

We do use extended holders as well as risers to be able to reach certain features. In the image below overall tool assembly is 25"+ long. We are using Big Plus and Capto in the image below.

That's quite an assembly ! lol

One more question...do you mix and mach big plus with non big plus holders?

I've used it in my old place and I tend to lean toward "trying hard" not to mix them on the same cycle.

What's your opinion?

Unfortunately we do mix and match big plus with non big plus. I would prefer not to mix them but sometimes when you have to order 100+ tools for a single project you try to keep costs down wherever you could.

Thanks Rob!

 

I'm going to Tolland for some 5axis training next month...exciting times

 

<cheers>

Very Cool Mark

If you have never been to CNC Software in Tolland you should be pretty impressed by their facility.

Please let me know if you are interested in meeting when you are in the area. I am about 20-30 minutes from Tolland.

[?Mark]

That would be great, thanks!

[Colin Gilchrist]

Mark/Rob,

 

If you two are getting together, maybe we could all meet up after work for a beer? I'll stop down in the training room for the Multi-axis training and say Hi...

[?Mark]

It's getting better by the hour...

I should be there the week of December 10th...but supposedly it's two people minimum so we need to find another "victim" for the class...

Rob, what's the material in that picture above? I'm guessing it's something expensive!

Joe, that would be a fairly large chunk of Ti.

That sounds good to me
