Converting I and J coding to R coding.

Is there a way to transform a post from an I and J circular interpolation to a R (radius) format?

Hello Josey,

Are you referring to the NC Program (Gcode file that is already generated) or a change to the post processor itself so that new NC programs are generated with different arc output?

Changing the post processor to generate the different arc output.

Josey,

Here is how you can modify the post-processor to output circular interpolation with Radius.

1- Open the post-processor file you want to modify in a text editing application such as notepad or notepad++.

2- Go to post question 221 and do the following steps

3- Make sure post questions 221 is set to “y”

4- Set post question 222 to “e” (radius)

5- Save the post-processor file

6- Post the code in BobCAD

Make sure when you switch to radius output that you also set the post question to break arcs at quadrants.

Also, you have to save the post as an “all files” under the type of file to save as or it will not be recognized by bobcad
