Hi-Torque slots in aircraft screws.?

Hi everyone. I’m new to this forum so I hope someone can help. I currently work for a company that machine Hi-Torque slots in the head of aircraft screws. Currently we use a dividing head, on a cnc miller to hold the screw whilst the cutter plunges into the head of the screw to the required depth. When this depth is achieved the dividing head rotates 7° clockwise then 7° anti-clockwise, the sides of the cutter are dovetailed so the sides of the slot become undercut to prevent cam-out of the screw driver. This set-up is quite over-kill for the job that we are doing, can any one suggest a simpler method? Any suggestions at all would be gratefully received.

If you had some sort of drawing I could probably get a better idea of what the part looks like. Right now, though, it seems that by rotating the head CW 7 deg and then CCW 7 deg, the tool is traversing over a section that has already been machined. Most likely I am just misunderstanding the proceedure, but if that's what's happening then it appears to be a waste of machine time. Instead of the CCW motion, increase the tool speed rpm and decrease traverse speed during the CW motion. This will give you a better surface finish with the first pass.
