4th axis z level?

[ Edited ]

Is there a way to get a 4th axis only toolpath?

For example I have a pocket with 2 walls angled to the C axis. 2 walls are straight.

My 5 axis is only a 4+1 so right now I have 2 z level programs at different rotations to completely machine the pocket.


What I was hoping to be able to do is machine wall, rotate c, machine wall, rotate c , machine wall,etc. I cant seem to get output like this as it wants to involve the A axis. I've never been able to get the lock axis to work.


I cant share the part so if what I just posted doesn't make sense I'll have to make some dummy parts and share those.

Rough or finish?

Sounds like finishing to me?

Assuming you ave checked out all the tool axis options (sounds like you have).

I'd try the following operation types:

1) Generic motion

2) Sequential mill


I'm not sure if roughing is involved.

Is it possible for you to post image of your part ?


In addition to Ken's suggestions, I think 'swarf' option will also work.

I have solution for this case. Exactly - two solution. I dont see your part, but - if your geometry can be "unwrapped" to plane from cylinder - I can generate Planar Mill toolpath, or Cavity, Or Z-LEVEL and - "wrap" toolpath back to cylynder.

Here - example -

Second possibility - postproceccor, when you generate Planar Mill, Z-level or another 3-Axis toolpath - and postprocessor convert it to 4-axis motions.

Here - another example -
