Need advice choosing machine controller for 5 axis router

Hello
I am very new to CNC control system and need to buy a machine
controller for a 5 axis cnc router that I am just finish building.
I am not looking for a high end solution but more moderate cost
effective option with good technology and open control system.
I have been told to look for a controller that has simultaneous
interpolation on all axes and has high block process speeds and
look ahead capability.


My plan is to cut larger shapes and contour machining of plugs for
Fiberglas molds and vacuum forming molds etc. and anything else that
comes in the door.

The router is designed to cut at 400 inches per minute. I will start
with the machine operating as 3 axis, and in the future go to 5 axis.
This router has 10mm pitch ballscrews 30mm dia. on xyz axes. The xy
moving table is 4ft by 5 ft and 30 in Z axis.
It will have a 9hp spindle motor probably Colombo. I have OneCNC XR
Cad/Cam that would be generating the tool paths in g code.

I am not clear on how to put together the control system and could
use a little advice.

Could you give me an idea of what CNC machine controllers to look at
and the components I would need to purchase. Possibly the names of
the better quality components and those that may save me head aches
down the road and be easy to install and get operational?

I was planning to use AC servo motors and drives as I heard they work
well and presently considering Baldor motors with their Digital
FlexDrive2 motor amplifiers. I am open to other suggestions and cost
effective approaches.
I realize I have a lot of questions but I sure would appreciate some
good advice.
Thanks
Peter
