Thread Milling on a HAAS Lathe

[ErikMichael]

Good Afternoon!

I am trying to thread mill on a Haas Lathe without a Y-Axis. I can't for the life of me figure out how to get it to post with the C-Axis instead of the Y-Axis. Any ideas? Thought? Help?

Hello,

Open up your postprocessor and search for gotPolarInterpolation variable under the //fixed settings, and change it to false.

var gotPolarInterpolation = false; // specifies if the machine has XY polar interpolation (G112) capabilities

After that, you will get the XCZ coordinates output.

Do not forget to set it back again to true when you finish with the threading operation.

Good Morning Ivan...

First and Foremost, thank you for the help!

I opened up the post but there is no such line. I tried searching and looking through it. I did find a line of "GotYAxis" and it is set to false. My asumption is that it wouldn't post in y?

The psot I am working with is the Haas ST-40 post. I did in fact find it on the ST-30 Post so I am going to use that for now.

THANK YOU AGAIN IVAN!

Hi @ErikMichael,

Always make sure that you are using the latest post from the post library:

I just opened the latest st-40 post and gotPolarInterpolation variable is also available there.

Cheers
