Engraving text using live tool on Okuma lathe

[emsee]

Please anyone know a software to help programming engraving text using live tool on lathe.
Text may be engraved on both cylindrical wall and end face.

Thank you.

Yeah. That is easy. You must be pretty new to CNC machining. How long have you been programming CNC?

Thank you.

Here is what I use on an Okuma VMC for the end face:
macro for serial numbering? (Delete the Mark code)
If this is of any help let me know and I'll dig up my cylindrical engraving macro.

Well, big help for me, and well done macro too.

Would appreciate your cylindrical engraving macro if available.

Thanks a lot Maxter.

OK folks here is my cylinder engrave macro for the Multus. (Delete the ".txt" at the end of the sub program folder name) It's still a work in progress but the OLL and OLR subs inside are proved out and working.

I've also included the Multus BLETTERS.SSB barend or flat engraving folder. It's the same as my VMC LETTERS.ssb program except for some redundant code in the character code that the Multus took exception too. (Strange that it would run on one machine but not the other!)

On the Okuma VMCs I don't use buffering but on the Multus I do. This was a problem since look ahead buffering can mess up how parametric code works. I played with M331 but finally added two 'stop codes' to get the macro to end. I used "EMPTY" on the VMC but since the multus doesn't have that I used "99" as a flag to end the macro.

Thanks Maxter,

I realize that "EMPTY" did not work too on my P200LA control, so
with "99" it should work, and also in the code for machining letters, the
"R" for radius did not work, I'll try with that macro that use "L".

I appreciate a lot thanks.

I remember changing that myself! Use the Lathe PGM "BLETTERS.SSB" instead of the Mill PGM "LETTERS.SSB"

I also noticed on the instructions for the cylinder engrave PGM I left off "DIA=DIA of cylinder to engrave"

I did a simulation with the macro and it only worked
with G103 or G102, not G03 or G02, I can see the number
on the screen but there's some strange mouvement with the tool,
at each letters the tool make big circle around the letters, I'll have to try
on a real part as soon as I have my milling attachement. (one week)

Thanks

If your using BLETTERS.SSB and have deleted LETTERS.SSB then it must be your machine or calling code. Here is an example of the Multus part program code:
