Best/Easiest software for 4 Axis CNC Taig Mill?

Hello everyone. I am getting a 4 axis Taig CNC mill and need to know
what the easiest to use software for it is. I have had experiece with
CAD programs, but am a complete novice at G Codes/Milling software. I
will primarily be using this mill to make miniature jet engines and
need it for the turbines or compressor blades. Please forgive me if I
double post this as I never saw the first message get posted.

Thanks,
