Vertical 4th Axis

[cbyrdmo]

I am trying to figure out how to use a 4th axis horizontally mounted on the Mill table to rotate the part on the Z axis to do the machining.  I only have 9.5" of Y and rotating the part would all me to machine a larger diameter part.

I have not been able to figure out how to do the tool path, whether I need to do a wrapped toolpath or a Tool orientation.  

Using a Tormach 1100 with 4th axis.   4th is on the A Axis.  Using Tormach Post 41497.

Thanks

So the A axis is pointing up into the spindle?

The easiest way, imo? Separate setups. Break the part into segments. Manually insert the A value you need. That's just my opinion. Are you doing hundreds of these, or is this a "one-off"?

Yes.  The A Axis is pointed inline with the Z axis.

Right now this is just a one off part and I could do that.  I have used sprutcam and it automatically did the rotation.  I am just trying to get fusion to do this.  I don't want to have to update my sprutcam.

If you want to make a post that does this, you could look at the C Axis post for mill turn machines.  

What you want is a post that has effectively the same logic (covert Y axis moves into C Axis moves)

did you ever figure this out? im trying to do the same thing on the same machine

I never found a solutions.    I look at several posts and I tried modifying one but I did not have any luck.
