Can I Trim PCB Edges With CNC for Wind Turbine Project or Must I Reorder Smaller Board?

Am doing an electromechanical wind turbine design that can generate free electricity for my people in the village. I had designed the mechanical structure early and also did some PCB design since i wanted to manufacture a product that can share some information through the phone eg speed of the wind turbine, the amount of power generated at a given time and so on. Due to some changes in the mechanical structure, the PCB cannot fit in the area we had planned. The board is somehow bigger. Looking at the boards components, they do not appear near the edges of the board and i think if i can trim the edges, then the board can fit. Can i cut the board edges using the CNC machine or I have to resend to the manufacturer for another production?
help!

Hello.
It is not convenient for You, to send the PCB back, if that's the only problem.
How large is the excess part?
In any case, you can cut it yourself, without problems, the important thing is that you do not cut copper conductive tracks.
The techniques you can use are as follows:
- jigsaw (manual or electric)

- many passes (above and below) with a cutter and then with the pliers you break the PCB
- shears

I read your wind turbine design. It is very informative and helpful to me.

thank you so much. I went ahead and cut it nicely and it really worked so so well for me. am almost done with the project.

Superb initiative! Good luck for the rest of the project
