4th axis operation for parallel-strategy

[Anonymous]

Hi,
I have a small cnc-mill with a fourth axis, which I would like to use more intensively 🙂

Now I started to play with Inventor HSM Pro. In the Beta-Mode I found the 4-axis limitation check-box already.
I setup a small modell of a crank shaft for playing (see snapshot). Is there a way to use a parallel strategy aroung the rotary axis. I found the "use 4-axis" option in the tool-orientation setup, but it seems its not working so far, or is there a trick?

The only thing what is working so far concerning the 4th axis is the fact you can use the multi-axis-contour operation to correctly mill out the inner edges of the crank shaft with only 4 axis. Anyhow I would like to mill the surfaces as well in 4-axis mode. Is there a way?

For now no.
Somewhere in the future yes.

Hi,
can you estimate a time, when it will be ready?

I'm very familliar with programming, is there a way I can support you? Could write some code?

The developers are working on it. Im not sure how far along it is so i cant comment on when it will be ready.

Hi,

two years have passed and still nothing? If there is no progress and even no time estimation I really have to think, if HSM ist the correct tool for me.

Im still offering my help as free programmer

Hi @Anonymous.

Totally agree: Can you please vote on this idea? Maybe that will kick it up the radar

Hi @ArjanDijk,

...done...

I figured out that wrapping operations are only allowed on closed pockets on the surface of a cylinder. Would be very nice, if one could reduce the diameter of a cylinder from 40 to 30mm, but unfortunately an operation like this is not possible at the moment.

From my point of view it is a very small step to create a diameter not aligned in the center of the x-axis, too. When this is possible I could create the crank shaft I mentioned above

Cheers Georg

@Anonymous:

That is actually possible by wrapping around with a sketch

You are not alone waiting.. I've even started to take a look at some other CAM software. I need that feature and would most of all like to have it inside of Fusion/HSM but I can't wait a much longer.

@kristjanpg06 You can do it inside HSMWorks, but most of the thing you can just fix with rotating the part and continue machining

This is also HSMWorks. A dutch company

Any updates on this?  Are we going to get some better simultaneous 4th axis toolpaths soon?  I do a lot of 4th axis trunnion work and have been struggling to find workarounds.  Multi positioning just does not leave a good finish and is very inefficient.
