Here's an oddball. I've got some parts I did because a local business needed a few prototypes fast. Well, they want me to make more but my pricing was too high. I had them redesign the part to get a certain feature (heat sink) so I could attack it normal to the surface instead of using a slitting saw at 90deg. There are cross slots (basically a bunch of rectangles sticking up from the surface) that have 0.125" between then and they are 0.5" tall.
Am I crazy to think I can try a small solid carbide high feed to quickly zig-zag down between these features? Side wall finish isn't important. I was going to use a Niagara N13996 since I've used those before in steel and have some idea for starting parameters.
Otherwise, ball end mill? Stub flute reduced shank?
If I can do this I can likely get the price in line with what they want. Otherwise, I'm not dropping my price and not making my hourly rate, I'll just pass.
