I need to cut a 1/2-13 od thread and I am just not figuring this out. Can someone walk me through the steps. I have a Centurion V controller.

First of all I am not sure how to call out the tool since it asks for the feedrate at the tool change page - do I give it the lead at that time even though it asks for the lead again in the threading cycle page?

Secondly, when I tried to program the thread I wanted to take multiple cuts to get to depth so I tried using the multiple threading cycle and selected "crest" rather than "root and height". Was that correct or is there a way to use another threading function and still take multiple cuts for depth?

When I ran the verify it looked ok but when I hit "run" it would do the truning part of the program fine but when it got to the tool change line for the threading nothing happens - it just sits there.

Help!

What is your software version? There were some changes in the software that can have an affect on the the answer to your question.

It looks like the version is T5.86. Does that sound right?

Still looking for some help here.

do not put anything in the feed rate , just the tool RPM.
Do a rapid move in X & Z to the start location - x .520 , Z .1
put this event just before the multiple thread set up page .
Crest will be .5
start position , same as the preceeding position : X .520, Z .1
You use the start pos in X as a larger value than the crest because this is the dia it will rapid back to the start end .
lead will be 1/13 ( on my Cent 6 , metric threads must be converted to inch dimensions and expressed in thousandths per INCH )

( assuming you will set z zero as the point of the tool at the end of part )
don't forget to go to the tool table and set tool type .
set cut depth to about .015"
min cut :.001"
fin passes : 2

once it starts threading , the feedrate dial is disabled , but I think you can adjust RPM override to slow things down.
Let us know if this gets you closer . I can post the full setup page if you need .
