4th axis posting problems

[allen.furr]

I am brand new to using my 4th axis on fusion. I have looked everywhere I can and I am confident I am not looking in the right places. If anyone could give me some direction as what I am doing wrong or a better way to do it, I am all ears. I am not sure how to load my file on here, so I can use help there as well.

Thank you for any help or knowledge given!

You can edit your message, or post a new message reply and attach your file (export from Fusion) in the area below where you type out your message. Having that would be the most helpful, but at the least need to know what kind of issues you're having, posting with what post processor for what machine at the least

Some screenshots could also be attached

Let me know if you can see this. I also included a screenshot of the post processor as well.

Are you planning on putting your 4th axis on an angle plate to tip it up and present the holes in line with the machine Z axis?

[allen.furr]

Yes I am.

Okay, sorry for the delay.

The reason that the post was failing is because Fusion is seeing this as a 3+2 program (XYZ, AB). Thus, some post editing was required to arrive at the solution.

First off: You're going to need to use a Machine Configuration for anything more than 3 axis work. In this file, I've created a simple Machine Config that will give you the settings needed. You can copy that Config over to your library and reuse on other projects.

Secondly: You're going to need to establish your WCS as if the part was sitting on a 4th axis rotary that is parallel with the table. It's a small matter to sketch out where that theoretically would be once the part is tipped up at an angle.

In this shared post processor, you will see both an A value and a B. However, the "B" is being posted out as a comment. This "could" be removed, but I chose the easiest method of getting you a post.

Here's the resulting code:

(Drill1)
N25 T152 M6
N30 S5000 M3
N35 G54
N40 G17 G90
N45 M11
N50 M13
N55 G0 A150. (B345.)
N60 M10
N65 M12
N70 M8

So, what you are saying is, I'll need to sketch the holes as if they were perpendicular to get Fusion to run the program properly and tilt the axis to the desired angle when I run the part?

[seth.madore]

No, just define the WCS as such. Take a look at the file I shared and copy the intent of the Setup
