Allen123 is on a distinguished road

First off you are turning a part.

It might be a good idea just to use your canned cycle from your machine instead of having BobCAD generate the tool path.

Depending on your post these canned cycles may be built in. I used the Fanuc 18I

Draw the profile you want to face

Select the profile and then go to the NC cam and choose the face canned cycle.




A window will pop up asking questions about the cycle fill in the blanks click ok




and then code will come up.

N10 G72 W.05 R.1
N20 G72 P30 QU.015 W.02 F3
N30 G0 X-0.0026 0113
N40 G1 X-1.2682 F20.
N50 Y5.605
N60 G70 P30 Q


Depending on what post you are using these steps will be different.

*** You can see I have something wrong because the Q is not calling what line of code to go to....





I think the issue with your file is you didn't have the boundary setup right. Try it again using a boundary like this.



This is what your tool path should look like. And you code will look like this:

So you can see running the canned cycle is better. Why? Smaller code and if you want to make an adjustment you can just edit the canned cycle.
