Heidenhain Work Offsets Explained

Heidenhain Work Offsets, traditionally the Heidenhain coordinate system was kept very simple. It was like the “Click and Collect” of the CNC World 20 years ahead of its time.

Anyway all you did was go to the place where you wanted as your offset and zeroed the display.



Simple as Jack Shit.

It even had a self destruct button.

With this button you could really easily delete programs by accident.

I vividly remember having to lie and cheat my way out of that one.

Fortunately they moved it, well it’s gone anyway.

Now this button Wow….. Don’t even get me started. It was still there all those years ago.

Watch this if you can’t stand the intrigue.

Back to Heidenhain Work Offsets

Nowadays everything is so complicated. I still can’t work the fuckin VCR and my central heating comes on in the middle of the night for no reason.

Not happy with one work offset everyone wanted six. Then it went crazy with extended work offsets some of you greedy bastards (and you know who you are) have 99. Come on that’s just debauchery.

Limitations with old Heidenhain Work Offsets

Joking aside it did have its limitations. Anyway now you can have as many as you want.

As we all know everything nowadays needs to be backwardly compatible. (I don’t actually know what that means, I heard a bloke say it in the pub)

Anyway the new machines have to still do what the old ones did.

From this screen you can make an offset active.

Once this offset is active any subsequent position move will be in this offset.

In your program you need one of these.

The above would call Datum 3

Above would call Datum 9

This would take it back to Datun 0

Come on surely you get it now.

The number (in this case zero) is the datum you wish to call. This would call the standard datum (can’t miss it it’s top of the list and it’s red)

Don’t forget this is modal so once selected the datum will be used all the time until you change it.

Now you have started using these datum you must have one at the beginning of each program. It’s a bit like taking out a mortgage (you can’t escape).

Obviously if you make it active in the datum table and then call a program. If that program has no datum call then it will use whatever’s there.
