Hello guys,

is there any good tutorial regarding CFM and Axis Optimisation?

I have a case that, whatever Preset from axis optimisation I use, the robot makes always the same thing:

Starts and ends are in the attachment

Because of the application I use, it is not good to change orientation.

Thanks in advance!
Kind regards,
Tom

You can find some information about how to deal with external axes here:

If you can share the RDK project and describe what you are trying to do we can help you better.

OK, thanks!

Ok, so here is my cell.

我有一个新N曲线”Test1过滤ew New New" and 1 CFP.

I am doing painting so I dont want the gun to rotate around TCP Z axis. IMHO, that should mean for CFP: Minimum tool orientation change and "Allow a tool Z rotation" = 0.

However, if I dont let him allow at least 10 Degs to rotate, he wont be able to successfully calculate the path. I wouldnt be a big issue but I see on the path that is going from up to down that the gun is rotated around 50Degs from the pose I wanted him.

Can you tell me what am I doing wrong?

Thank you very much!
Kind regards,
Tom

Can you please take a look at the cell?

MANY THANKS!! :)

I have looked into your station.
The Fanuc P250i has non-standard kinematics.
You can limit the maximum allowable range of rotation around Z:

Hello Sergei,

thank you for your reply.

The solution you suggested is unfortunately not working. As you can see in the attached 2 photos, the X arrow from the TCP is not following the path. Any suggestions on this issue?

[Sergei]

OK, if I understand correctly - you want to align the tool in the corners of this zig-zag path.
Please, try the following settings:



In addition, as the rail limit affects the robot's posture at the end of the track, additional points need to be added to the last part of the path:



If you want strictly follow the path with TCP - I'm not sure that it's possible for this station.

I attached a modified station.
