Tool Path Generation Issue

[ianober]

I am just running through some of the tutorials in the manual and have hit this problem in more than one. I try to generate a tool path on this basic facing operation and it comes out all screwed up, any ideas?

I attached a word doc of the problem. The path should be completely vertical but it is slanted, not sure why.

Forgot to mention that I am running V21.

This could be caused by a couple of things. Make sure that you choose the vertical line first when your picking your geometry for facing. Also, check to make sure that the direction of the lines go from front to back and from center to od. Upload your file so we have a better idea of why this is happening.

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.

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.

Allen... You're one smart cookie.
All your tool geometries in one file so you don't need to go looking for them in the directory.

Thanks,
