Tool offset patch

Why is T10004 not wear offset 100 and geometry 04?
I thought that the patch only covered tools up to 99?

T10004 is not a valid tool number to call ( there can not be a tool number above 99 in Fancuc lathe code as I understand it)

but it is a valid entry in the toolfile - its the wear offset #4

wear offsets are given a 10000 offset to differentiate them from geometry offsets.


Also the first two numbers are geometry and nominal offsets, the last two are wear offsets (opposite of what you quoted)

Sorry About that Chris I thought I attached it.

Here is a copy again.

I don't know what the problem is. I will have to go into he office and attach it. The pc at the machine wont do it for some reason.

I just remembered, it wont attach a .tbl file.

Ok one thing I'm seeing is everyone thinks tool entry 10000n is for wear offsets.

It is _not_.

It is for geometry offsets. (the patch is very clear about this)

As long as you never enter a toolsetting it wouldn't matter.
But the toolsetting button overwrites the T10000n entry not the Tn entry.
Thats an important difference.

As the patch stands:
geo offsets are entry T10000n
wear offsets are entry Tn

I personally think this is wrong too. But I didn't write the patch so i don't know why that was done that way.
I am trying to find out why on the maillist.

It would make more sense to _me_ if the geometry offset for tool 33 was in tool 3300 and the wear was in tool 33. (in the table). And even more sense if they were reversed.

Actually, it would make more sense if both sets of offsets lived in the tool 33 row of the tool editor. And if the Gcode used G10 L1 PNN QNN.

But we don't get to make the rules.

You need separate lines for wear offset and geometry offset because the wear offset does not have to be the same number as the tool number.

T101 and T102 are perfectly valid tool numbers in a program (same physical tool different offsets)

Well need is too strong a word. but it would be easily confusing the other way.

Hello Chris,

I have been following the thread on the developers mailing list, and realized that I might have been mis-leading on this all along. Sorry for any inconvenience.

A few things I am sure of on our end,

1. The first two digits of the tool call is the tool geometry info on our other machines, for the most part also refered to as "Fixed Offsets".
2. All of the machines in our shop that have other commercial controls on them, all have 2 different databases or tables, Fixed offsets, and Wear offsets. So as far as I can tell when the tool call is made, the first two digits gather info from the Fixed offset file, and the second two digits gather info from the Wear Offset file. Once the operators have all of there tools touched off they vary rarely reference the fixed tool data, due to using the G92 command they only need to touch off 1 tool on every new part, and everything else follows.

Thanks

Rick
