Mazak Chuck Barrier

[MultiAxGod]

I was wondering if anyone has any information/knowledge fo Chuck Barriers for EIA programs for the Mazak 640T Control.

I have gone thru the manual and there are a number of parameters but not much information as to what really controls what. Am running an EIA program, bringing the turret close to the chuck but the barrier is stopping me 5mm away from my cut position in "Z". Company has run Mazatrol programs this close but this is the first EIA program and there seems to be different parameters to handle Mazatrol chuck barriers and EIA chuck barriers.

Just wondering if anyone has experienced this also and if so, what parameter number or combination of parameters it is that handle the "Z" barrier definition.

 

Thanks

Never used them in EIA. I always know where I am going in eia so never had a need. I would contact Rudy at the Service center here and see if he can get you some information. May have to G10 it in once you find out what is what. I have not forgot about the Manuals, just been busy.

Check your mailbox... Not sure if it will be of any help at all, but @ least it's easier to search in a .pdf then those crazy manuals... Also it's for Matrix.

Can you change the chuck jaw definition?

Believe these are the ones you want, from the Mastercam Mazak Integrex post.

 

# B251 = -1000000 Cancel sub-spindle barrier

# B254 = -1000000 Cancel tail stock barrier

Thanks guys. For the moment, it looks like I got around it with BA19 Parameter setting. Increased it from 1387475 to 1500000 and my tool was allowed to go to the chuck without barrier alarm. Not sure if this is the best fix or just happened to work.

Thanks, Ron.

Got 'em Rob and will look thru them after a bit.

David, I have been trying to figure out the chuck definition and the turret tool offset combinations. Can't find any good drawings/descriptions in the book to make it more understandable.

My barrier Parameters only go to BA132 Steve.

 

Thanks guys for all the quick help.

read a little more and we have a Quickturn Steve, not an Integrex, so no sub spindle.

Thanks Rob, but these are the same as my manuals. Still can't figure out these definitions for the chuck/jaw types and the turret so I'll have to experiment some to find the answers or wait for Mazak techs to respond!
