your ideas on a pipe profiling machine

[D-man]

Im looking for some good people to help me with a project that im going to be making.

I currently own a Swimming pool filtration company and we deal with alot of under drain systems for the swimming pool filters.
The underdrain systems are built using 2 x 160mmOD PVC-U pipe ranging from 2ft per side up to 5ft per side, however most of the customers want to spice thing up a bit by making them bigger or changing the design, so we will just stick with those sizes for now. The two halfs are then glued into a 160mmID PVC T peice to make one unit.

In each half there is a number of holes that some 1,1/2" sockets are then welded into. these holes are then also mirrored on the opposite side of the pipe for each end of the socket to stick out of.

I would like help to try and come up with some design or use an already proven plan that may be available.

What should the router/profiler do?
The machine should be able to cut rounded holes along the center of the pipe (any kind of shape really). then the machine should be able to spin the pipe around and mirror the holes on the opposite sides, perfectly aligning with the opposite holes.

we do a different range of underdrain systems so the pipe fitting must be able to accept a pipe from 1,1/2" up to 8"

Hardware i have
Nema 23 motors x 3
drivers x 3
controller
supported round rail x 4
bearings x 8
ball screws x 4
lead screws x 4

all i really need to come up with is some sort of design. im guessing the design does not have to be wide, just wide enough to accept the largest bore pipe i will be putting into her. And for length im going to keep it simple and go for 5ft

any help getting me started on this project would be greatly appreciated

please see diagram
