what size machine is it? some specs maybe?
You want to take 1/2*diameter at MAXIMUM the feed rates. I sure hope you arent planning on pocketing all that out with that tiny end mill, It looks like you will want to re-draw that a little to include toolpaths to make it a little easier to machine.
Is that O-ring groove correct? it has some sort of radious in your drawings
You will definately want to use coolant while machining that, its quite hard on those small end mills to go without. Youll want a really high spindle speeds.
Do you have access to a 5 axis mill or something? I dont see how you are gonna cut that jet thing.
