Problem- error44 check pocket

[dek]

Error message 44 check pocket has come up on the screen (ITNC530 bridgeport 5axis) i have gone into error messages where it says you can cancel it which i have done , but it still comes back but the machine still runs with message still up .Anybody have any suggestions please

so obviously a 1957 Monarch right?


info please

did you accidentally program to an empty tool pocket? Or does it check all tool pockets and want to see them full?

Ive only just started in this firm so i dont know to much of the history of this machine but i know its not a 1957 monarch ,i have spoken to the chap that used to work on this machine and they had a problem in the past with the toolchanger.He has looked at it with me and although i am picking up tool 31 it is taking it from position 30 ,this was like this when i started but only now the error is coming up.

You realize that no one can help you until you tell us what machine it 'is'


Go learn some things and then come back

Since it is an iTNC530 control you have one of the XP3 or XR models. That tool #31 is in pocket #30 doesn't matter, there is a pocket table that keeps track of what tools are in which pockets and it is usual for tools to be place back into a different pocket then they were taken from.

I don't have an error code list for a XP3/XR with a Heidenhain control however I do know there is no sensor to tell if a tool is in a pocket or not. The only sensors that deal with pockets are the ones that check if the pocket is up or down. Check to make sure the pocket is going all the way back up after the tool change and is not slow on making the up sensor. You can also program it so the pocket stays down after the tool change and see if that gets rid of the alarm. (open up your Hardinge operators manual and it will tell you how to do this)

If that all is okay check the pocket table (the Heidenhain operators manual will tell you how to do this) and see what the control thinks is stored in that pocket

I have 3 XR's with the 530 control(only 3 axis tho). I don't know what error message comes up but we get problems with fine ally swarf getting in the grease around the pockets. We have to take the covers off and clean everything then regrease and we are good to go for another few months.

That's likely your problem. The chips are preventing the pocket from going all the way up or are setting off the down sensor. If it is not possible to shield the pockets from the swarf you might be able to set up an air blast to keep the chips blown out of the area. Otherwise you'll just have to make it part of your pm's to clean these out.

While we are talking about pm's, the XR's and XP3's have another essential part of pm's that does not show up in the manuals. When you grease the X axis linear guides you will have the way cover pulled back. While you have this cover back look under the ballscrew/motor coupling and also in about the middle of the casting. In the casting there will be 2 drain holes about 1/2 inch in diameter, these holes have a tendency to fill up with chips and allow coolant to fill the pocket around the ballscrew. Make sure these holes are clear and coolant is not standing in this pocket. This has been the main cause of x axis ballscrew end bearings and ball screw replacement that I have seen on these machines. If you are cutting anything with large light chips (like aluminum) they are more likely to plug up.

Look in the tool table section. The Bridgeport/hardinge user manual is only about 50 pages.
