They said they do not support them.

True story one of our matsuuras came in as cat so they shipped us the fingers from a demo machine in Minnesota while they ordered the replacement fingers.

This might be dumb but I'll put it out there anyway. If I recall correctly a few years ago when we got our Quaser MV184 the first time we went to tool change it alarmed out. The guy helping with the install changed the "hands" on the ATC and the issue was fixed. I believe he said the machine could run CAT40 or BT40 by just changing the ATC "hands". 

Possible this is the case with your machine too? Again, I could be way off here.

Yes it's just the fingers on matsuura

Haimer makes holders as well as lyndex. We use haimer shrink and their er collet holders. We have a few lyndex slim chuck and dream holders also.  Command also but they don't make their 3" er11 holders in bt40 anymore 

On the website it's not listed. We may be acquiring a used 500u with the HEIDENHAIN  control .  

I usually only combine two ops in one group if I have to share a lot of tools and am flipping between one side then the other with each part.

I ordered a ypl drill I'll see how it works

Do you have the filter turned on to make arcs in x and y?

It's possible that controlled definition is forcing linear moves

Usually you would have a g49 above it, then activate the tool offset.

It's been a while but on the old shops 2xi we used g5.1q1 but I believe the option was g5.1 P10000

Is it fanuc or their new os

IMHO, that's too much feed for Titanium to keep a straight hole and for the drill to hold up.

I'd be .0015-.002 ipr and about 110sfm, for best hole quality I would use a Kennametal YPL drill, three margin, acts like a gundrill.  For the cheapest thru coolant drill option I would use a Kennametal GOdrill.  Marginless, won't bind up in the hole, usually very good bang for the buck.

Thanks.

I went back to the guring firex for now. I'll look at those

About .005"

I put a small spot in and it helped. I changed the drill and lowered the sfm. I'll see if it holds up

I have an Amazon ender 3 clone

We are cutting grade 5 titanium and the website says 4000 rpm at 19 ipm for a .177drill.

I tried it at 85% of that and it didn't like it. It walked pretty bad. 1 inch deep .177dia 1200psi tsc in a hammer shrink. No peck and no spot drill. It was at 13%load on the mam 72-35v.

Anyone use these in titanium before?

It moves a lot. Let it sit in QC for a while to acclimate 

This is where the circles with lines comes in handy I believe. Use hole axis and get yourself a line 

I think if you you under updates you can pick just the Camplete 

I haven't figured out if you can omit it from a new install

Sounds to me like you have a tuning issue (low likelihood) or hardware issue in the drive board to me.  If your Z-axis uses the same drive board as X or Y, you could consider swapping it with another axis and see if the problem goes away.  If that's the case then you have a bad drive.  There may be more sophisticated testing you could do.  But I am uninitiated in troubleshooting them by means of anything other than plug and chug.

Do you have more than one of these model machines to compare with?  If you feed it up in z slowly, stopping and starting frequently, is the load dead smooth and repeatable?  Unless you have a right angle head, you can't really easily do a test that would repeat an issue I once had.  But if you side mill while compound feeding that axis with another while it is loaded (Z+) , you would be able to see it clear as day in the finish.

we have two but one is manual guide i and the other is the new ihmi.  but they do the same thing

Here's why I don't use that often..

By creating a closed contour, I can set a reasonably steep ramp around the contour. In the end, many times that is faster that the re-machining option.

I can take 2 ramped passes around when using the remachining option I generally need many more step downs.

plus re machining doesn't respect internal radius

My question was more regarding the actual "angle" of the tool deflection. From my experience, I find that if I take a heavy enough chip, I get deflection, and a tapered wall.  Using radius comp will just move the position of the taper.  Sometimes it seems like a spring pass is the only way to get rid of that taper, which can sometimes result in a bad finish.  

So asking questions isn't allowed anymore?  In my opinion, that mindset, is part of why this is becoming a lost art.  

i usually use a stub flute and have to step it down

What does the load look like while it is cutting?  Does it fluctuate greatly?  Maybe the inertia parameter isn't set right and happens to react with that harmonic?  Have you tried faster or slower spindle speeds with success?

It has spikes in the red when it starts to grumble. Raising the rpm usually helps

The sound of chips hitting the window, Fanuc controls, seeing my wear offsets all running on zero, and undercut tools.

I used to work with cranky Hank and he would have .499 .374 ect end mills in his programs. you should see how he adjusted his threadmills

it rounds the top even with a flat endmill.

if the corner were shart technically it would have more material on it than what you set. there is a setting for stock to leave not to round corners in contour. maybe something similar. or a check box in tool path fillet to make sharp

in the graphics world up and down is Y and z is depth in the monitor view
