If you feel grooves, it needs to be machined. If you replace the pads but leave the grooved rotors, the pads will wear unevenly from the beginning. To optimize performance of your braking system, the brake pad should be mated to the metal surface as much as possible. These grooves take away from that process. The same is true with warped rotors.
