Thanks just got it when checking back

Have to make a few new sub-plate for one of our older machines.

Finished it a 24.802 square with 45 degree x 2.5 corners.

It's going onto a horzontal to mill all the sides.

The question is how to trim the corner toolpath. There will be a LOT of air cutting with a 4.0 face mill.

Take a look at the picture. It's in top view, not the 45 degrees for the program.

Thanks

Not sure, I'll give it a try

We have a Siemens 840D Powerline control

One of my maintenance guys is asking to put a dwell into the program. Anyone know the dwell command for a DMU50? I tried the standard g4 p1 and get an alarm.

Thanks

Columbo, is that particular tool shorter than all the rest?

Both center drill and drill have the exact same gage length...

can you watch the load meters when the tool is in that position?

Anything suspicious there?

looks normal right to the e-stop.

Yeah, that sounds like your drive board is fried. I used to get those all the time and thats usually what it was.

Call up your friendly service guy and then hurry up and wait 1 week for the new board to come from Germany.

only the one tool......other tools that go to thame position have no problems

OK peeps....gets even strainger.....

Machine used to only go into e-stop BEFORE the centerdrill ran at the index stated.

Now it does it, and NOT all the time, after the center drill is finished. It NEVER does it at the same index with the drill......

Here are the machine alarm numbers...

25201 - Axis B1 drive fault.

300608 - Axis B1 drive 5 speed controller at limit.

510305 - Emergency stop: Drive B axis is not ready.

3000 - Emergency stop.

510311 - Emergency stop: E/R module not ready.

^^ ^^

WOW....gets even weirder.

Had to break down the job to run another hurry up job. No problems, lots of rotary moves.

After the reset-up of first job, back to the e-stop BS in the same spot. It took about a half a day completeing about 20 parts before the first e-stop alarm.

Hi James... Welcome to the Forum.

Goes down on line 860 (again, not all the time)

If you have the time, can you program some incremental rotations back and forth and run in a loop to see if the problem happens in the same spot consistently? Just on the center drill is weird....

WEIRD.......YES...very

Made a looping program and it ran fine. whent back to the production program.....same $hit...

Checked the program all is good.

Copied the drill and changed the cycle 83 to 81 and changed the drill depth for the center drill....e-stop AGAIN...

BTW.....this machine is past weird.

ours is a 3+2 also....

The machine goes to an e-stop

The wierd thing is the only time in the program it shuts down (and not all the time) is on the center drill. The drill later on never, as of yet had the problem.

No limit switch....it works most of the time, just recently it's been acting up. Been running the same parts for weeks.

Heidenhain control?

 

Sounds like a problem with the position monitoring. I think there is a timer parameter or something similar that can be increased slightly to overcome the problem.

Yea....thanks, I'll get someone on it

not a DMU guy, does the load meter spike while trying to rotate?

Nope, makes the rotation and the next Z move and then the alarm. (but B never got there 100%)

We have a DMU-50

This does not happen all the time, but today even after a restart it happened three times in a row.

Program sends machine to C270. and B95. Machine goes to C270. and B94.98971 and goes into e-stop.

Any ideas???

service people have no clue....

Thanks

The flat at the bottom MUST be defined correctly. I usually program a test hole where the c'sink would come out .1 undersized or something. To ensure your getting what you want before its to late. We have a shadowgraph type tool setter. I will tell the operators to set the tool length offset where the angle meets the OD of the tool, this eliminates most of the error.

+1 that's what I do.....no guess work.

^^ Yep......what Jack said....

Happened here once also...Dumb DMU's

We had to call the tech in. And the fix was too effin secret.....guy wouldn't tell us $hit

Thanks.....

Knew it was somewhere...

I am trying to modify a SFM to 2500 and the FTP to .035 and the feedrate goes to a strange italic. I checked the post and the max cutting feed is well above this. Where else should it get changed so the actual feedrate appears instead of the strange 500 I get now?

Thanks

Also make sure that your Helix support is set to "all planes supported".

Yup....

Do you also have the box checked to allow 360 deg arcs?

YES

After I post the arc gets split into 2 quads. I checked the post and the control def. and they both say DO NOT BREAK ARCS...

Am I missing something somewhere?????

Is there a way to lock the spindle to tighten and loosen an expansion arbor?
