I do not understand. It seems that the more the tool wears the harder it is cutting ("more spindle load") for this profile (fz 30). I would imagine it would be the other way around. This is without changing the radius offsets at all. Please help. We are running spindle seed 5500 rpms and feedrate for the first segmented at 80 inches a minute. The next two tools the coarse and medium are at 5500 spindle speed and 140 feed rate. Stock left at .014 to .004.

The more the tool wears it is causing your load to go up?? You must have a glazed set of tools.

Agreed. You probably need to dress your tools. Look in the digital forum for some videos on dressing tools.

I would also check your water supply through the tools by doing a gpm test. Preferably while your running other tools requiring water. Not enough water has caused most of my problems in relation to tooling and load.

Who are you?

Where you located?

What machine?\

What tools are you running?

Are you dressing your tools?

What's a normal gpm for most CNC equipment?

15-20, I think.

Northwood is 15 minimum. 20 would be better

That's the combined total between the spindle and the halo?

Yes, combined total through both. When I test, I like to test the spindle only at the spindle, to make sure I am getting good volume.

Just turn on the internal water with the spindle idle and the finger bit it. In should shoot straight out of each hole a few feet horizontally. If it isn't you have a problem.

Dressed the tools plenty of times (went through 3 sticks) (1stick for position 4) I dont think that seems to be the issue. I have re-set up the tools manually twice and that helps a little bit also I found that if i did 2 passes with the segment and get it to about .01 stock on the second cut it helps quite a bit. It seems that when i was taking away the max stock per pass with each tool I would only get to go about 15% to 20% 9 to 12 inches a minute. By reducing the stock removal per pass dramatically I was able to crank it up to close to the max feedrate of about 60ipm for the segment and then 70 to 90 ipm on the 2nd and 3rd metals.

What Dustin is trying to say is would you please update your profile so we know a little bit about who we're talking to when you post!

I am a Cad/Cam Designer also can operate cnc's.
We have northwood fabcenter

Damn, wish I had known it was ADI sooner. I have been with Rick (one of our tool tech's) all week. I will try to get you an answer tomorrow afternoon.

Sorry about that, I talked to Rick Mount on the phone a few days ago and he walked me through re-setting up the tools and that helped a bit but i still dont seem to get a maximum feedrate.

We changed the water filter and that seemed to help quite a bit. The water pressure or flow was fine coming out of the spindle but it seems that the dirty water glazed the tools up a lot quicker.

if your tools are glazed too much, you may need to run those black sharpening bricks. A lot more coarse to open up the diamonds. Don't press too hard, for it may mess up the shape. Just press it into the tool for about 10 seconds. Then run your normal white dressing brick.

We run the exact same tool on the same machine. Pos.1 @ 80 - 1 pass, Pos. 2-3 @ 120, Pos. 4 @ 80.

Maybe it is the stone itself. Have you cut any juperana gold light or tropic brown. The Juperana gold light isnt too bad but we are still not cutting at the optimal feed rate. The tropic brown is horrible we are cutting with 2 passes each the spitfire and segment and cutting about 20 ipms. I definately think a lot has to do with the stone but I still think I should be able to cut at those speeds you said on the juperana gold light. If not let me know. Thanks or the advice we may need to try the black dressing bricks.

Thanks for the reply,

Garett

you cannot run cnc tools at 9IPM or you will glaze them....I think perhaps you might have been running them too slow. If they are ADI UHS, you need to run them where carmine is. 20IPM will glaze them up too.

Agreed.

We are running the feedrates I stated on ALL stone for the most part. Maybe a hair, I mean a hair, slower on tropic brown. But not much.
