I'm looking for suggestions on the best way to cut this nozzle cavity. There are 3 steps, all flat bottom. diameters ranging from .098 to .272". All diameters have a +.000, -.001 tolerance. All 3 diameters have a nozzle that gets pressed into them. The press fit needs to retain the nozzle, and seal. What makes this the most difficult of all is sometimes I have to have my tooling sticking out 4-5 inches. Currently the way I am cutting these is with a helix cycle followed by an interpolated circle to finish. I'm leaning towards getting a custom form tool made to cut this, but the depths and diameters change quite often from part to part.
I'm having a huge problem with tool deflection cutting them the way I am. Management just tells me to "ream" them with a reamer ground flat. However I don't agree with doing that. Does anyone have any suggestions as to how we can do this better? There has to be a better way!
We machine these cavity's into lots of different materials... Acetal, aluminum, 1018, 4140, a2. So you can imagine my issues in the harder materials with lots of tool stickout.
Thanks for any help!
