Proto Trak Lathe Post Question (RLX Software)

[MachinistJoe]

I am working with a Proto Trak Lathe with the newer RLX Software. I am having trouble with the finish dimensions of my projects. Through trial and error I have found that adding the insert radius to the "Stock to Leave" tab seems to work. My question is: Can I change this in the Post? My worry is that I will miss doing that and scrap a part. 

Thank You for your help!

It sounds to me that there's possibly something else going on. Do you have a Tool Offset page where you input the tool nose radius? Are you using Computer or Control compensations?

[MachinistJoe]

Yes there is a tool offset page. I have tried all the settings and have found the "Tangent" setting to be the one that is closest to what I need, but still need to input the nose radius into the "Stock to Leave" window in order to generate the correct size. I am using the computer for the offset though.

I am running into a similar issue, I tried different tool points as well as in machine and in computer offset. It looks right when I simulate in Fusion but not on the controller, it is off by the radius is what it looks like. Mine is more noticeable because its a button tool. Any solution or ideas yet?

I contacted TRAK and they told me to contact Fusion as there may be a different post for the RLX controller?

Sounds like your controller is running off the center point of the nose rad and not the actual tangential "corner".

According to the TRAK lathe it is it is the tangential corner, you don't have the option to adjust that in the controller
