Slow 5 axis

Hi,

Actually we have a setup configuration with two motenc pci 4 axis witch work pretty well with 5 axis, except when there are a curved surface, when the speed slow down.

We are in process to expand two more plants and would like stay working with the same setup but despite all our efforts this speed problem can not be resolved.

Can anyone please help us with this problem?

I have attached the configuration files and a application file for visualization of the problem.

Also, I have upload two videos to Youtube for best show what was explained:




Thanks,

The files you mention are missing.
I assume this has something to do with the F-value when running 5 axis. Perhaps not properly calculated (just a hunch).

Thank you Hakan.

I have include the missing files on this replay.

Yes I think the F-value when running 5 axis is not right.
Your machine run in millimeters, and starts in G94 feed rate mode (mm/min)
It should run at F10000 which it might seem to do from the video.
Then check at the line starting with G93, there it switches to inverse time feed mode.
The x-y-z distance between the G93 line and the line below is 1.0798 millimeter. The time to complete that movement should be 1/1140.4932 = 0.00087681 minutes. This means a speed of 1231.5 mm/min. That is quite a bit slower than 10000 mm/min that are specified when the B and C axis are not moving. Even if that is the axis speed and not the tool tip speed, it is not far from and is so far from 10000 mm/min that it is safe to say that it is the F-value that makes the machine go slow.
