[Bensa]

Hello forum friends thank you for watching this thread.
First of all excuse me if my English is not so good.
I'm from Holland so it's not my foreign language.

So lets start i have a one of a kind 5 axis milling machine.
Build in 2002 with the siemens 840d control.
It has the latest version of the Powerline but without the swivel cycle 800.
You can select cycle 800 but the kinematics are not set in the parameters.
Talked to siemens and they cant help me with it.
They won't guarantee to come with a solution.

So now comes the problem i can't do 5 axis positioning and simultaneously with Onecnc.
5 axis positioning can be done playing with macro's variables whatever but i don't want that.
What i need is a cam program if the table swivels the zero point of the workpiece shift together with the b axis movement.
In the 3 pictures you see the machine in 3 different positions.
One with the b axis at zero, one at 45 degree and one at 90 degree.
So for example when the b axis is at 0 degree.
Then let's say we set G54 X Y and Z at zero in the center on top of the block.
Then when i swivel the B axis at 90 degree the top of the block pointing to the right is aproximately at X440 and Z-35.
What i want is that the software continous milling at that point without making new zero points.
For example when i want to dril a hole 50 mm left from the top of the block then the x axis must be on position x390mm, (440-50)
This is what the software must output.
This shifting also must be done in the z axis.
Now i have to make different zero points G55, G56 G57 and so on, i have to zero them side by side.
And then paste all the program sections together.
This makes working with 5 axis a pain in the *ss, when making 1 or 2 parts.
It only makes a profit when large quantities must be made.
And don't forget the danger for making a crash.

I hope you guys understand my question.
Here in Holland the seller of the software can't help me, it is a shame.
They don't even know if it is possible.
They only can tell me they have a Siemens 840d postprocessor.
But that won't take away my problem.

I hope someone can help me, if this can be done then i start studying Fusion and take some lessons.
Kind regards Bensa from Holland.

The pictures, notice the milling head is like a normal vmc.

Fusion will do 5 axis tool paths. But I'm not sure if the B axis offsets are done in the controller or in Fusion.

I have found the Titans of CNC Academy https://academy.titansofcnc.com/ to be the easiest Fusion tutorials to follow. It's free, and they take you from no experience to 5 axis in a few lessons.

There is a lot to find on the internet how to program with fusion. But my question I haven't find a answer for.
