o/t, spindle warm up @ start of prog.

[Jammer™]

I have a rebuilt fadal with 10,000 rpm spindle. In the mornings, I run a warm-up cycle with spindle in low gear before running any programs. But when running programs at 10,000rpm all day and not going into low gear, the belt sticks and makes all kinds of noise and sometimes won't even rotate. (not good) My question is: Is there a way to add something in my post that will run the spindle for 5 min. in low gear at each tool change, before next tool runs? I am using mpmaster fadal post. Thanks

I THINK This may be what your lookin to do if so shouldnt be hard to incorp into post

If you are having problems with the low gear on the fadal, I would check the hoses to the hydraulics that change belts on the head. They do tend to leak and get sticky. Order a new part and replace it. Easy swap out. We normaly have to order those parts every 3-4 years on our fadals.

Jammer,

 

in the "ptlchg_com" post block

you could hard code something like this:

 

n," ","S100M03",e #Set the speed you need

n," ","G04P???",e #set the amount of dwell that you need.

 

Hope that helps,

Okay I manually typed it, and it needs to look like (this is a 15,000 rpm Fadal)

Now the trick part on to marting's post mod to get it in there

[Jammer™]

Thanks for the input guys. I will check it out today, and let ya know the results.

Madbub,

This machine is only 6 months old. I would hope were not having issues like that yet. I will check it out though. I did already have to replace the belts. Thanks again peeps!

HI

Wow, I'd think it would be more cost effective to have the machine repaired than to add 5 minutes to every low gear tool change?? I've had to couhg up some $$ for the tree guys to get my machine up and running, but all in all it waqs money well spent.

 

Good luck

That is just messed up. No wonder the US can't compete with Asia, too busy screwing around with crap like this. Rebuilt Fadal... that's like a rebuilt Yugo. I'm sure it looks pretty though.

 

Sorry for the rant...

[crazy^millman]

Agreed 1000000% James and no offsense to my fellow forum members or my place of business.

[Jammer™]

We have had this machine for 6 months. I've had the service guys out here 4 times already for one thing or another.

yeah, it has two pretty stickers on the front. One says Factory rebuild, and the other says Made in the USA..

[Teh Bear without Brains kinda idiot]

I would replace M3 code with custom macro .

Not havin` Fadals (GSMF (G_d save me from ) Fadal ) i will talk schematically

 

Macro program gets looks like p100=7000 m333

or #100=7000 g333 or some other appropriate for Fadal way

Saves a speed s7000 setted for a tool in inner parameters

Checks if spindel turns and on what gear

if result -low gear skip and go to

m3 p* something or g4 x or whatever fadal has for wait 5 minutes

m17

if result high gear go to low gear

for s500 m3

g4 x300

m5

go to high gear

s(input saved inner parameter -needed speed )m3

m17

 

end

 

You will have a good way to use it even through MDI or in hand written code if you save it as custom macro G-code or by any other appropr. way

Here is a program I used to warm up a Fadal. I use sub's. I left this program in memory and always over write programs being ran. This is the only one that stays in memory. Easier for the operators. The sub also moves the table and head in 3 axis moves just to get the juices flowing. Plenty of time to cycle the spindle as the table travels.

 

If you would like, I can email you the file.

Hey Trevor, How ya doin man? Hope everything is goin well for you. I have a program wrote to warm up the machine in the mornings. What I am looking at doing is running the spindle in low gear for a couple of miniutes at each tool change on my high rpm programs. If this spindle doesn't get any low gear run time, the belts want to seize up.

[Trevor Bailey]

If you want to do this while you are running a program (or before the ACTUAL program begins), you should be able to set up a flag in the post that could be turned on with an integer. If you need help, I will set it up for you. Let me know if you are running the last Fadal post I sent you.

 

All is well on this side of the world. Miss the beautiful green country side though.

[Jammer™]

Trevor, check your e-mail. Thanks

[Rich W]

Trevor, could you possibly e-mail me the file you posted above along with the sub you mentioned. I am not familiar with programs that can be run for certain time limits and would be very interested in seeing how it was written Thanks

Well you did say rebuilt, so I thought I would mention this. If it was rebuilt, the machine under neath is problay alot more older than 6 months.

Jammer, check your inbox. Let me know.
