5 axis trunnion type newbie was created by alaamomen9
I'm trying to make this machine
i've started from reading kinematics wiki in website !
but this type wasn't existed !
how to start to implent this type and make it moves corecctly!!?

That uses normal kinematics nothing special to do.

so how the emc2 know cutter location!!?
to 5axis machining!?

When rotary axes are used LinuxCNC does not know the cutter location relative to the part, it only follows the G code. It's up to the 5 axis CAM program to sort out where to go.

Ah you have surpassed my skill level, I've never CAD/CAM for a 5 axis machine.

That's not necessarily true. Whilst it is possible to use that machine with trivial kinematics and with the tool paths calculated in the CAM, it would also be possible and arguably better) to set the machine up for TCP.
There are some rather mathematical docs here:
linuxcnc.org/docs/devel/html/motion/5-axis-kinematics.html
Which are directly related to the machine type you show.
If you install the development (2.8) version of LinuxCNC there are simulators that you can experiment with (the screen shots in that docs section are actually from the simulators)
