Cylinder combustion chamber softening
Posted: Sun Jan 14, 2024 1:55 pm
Good afternoon everyone.
I tried to post this yesterday, but as I was about to hit the button the server was down all into the night time.
So here we go. I made a trunnion plate system for my 4th axis last year.
I have 2 plates. 1 plate has all of the dowel pin locations and bolt threads for machining cylinder head intake and exhaust faces.(not shown).
2nd plate has dowel pin holes and bolt holes with the chambers opened up to machine fire ring grooves and any chamber work. Now what shops are doing is machining a taper on the quench area. This has a diameter of 4.00 inches with a 5-7 degree taper inwards to center. This helps control the flame burn on nitrous added engines.
I did look around inside Intercon and can not really see a way to do it. I see the circle pocket but no way to taper out the Z on the cuts.
My friend is writing me a program I am assuming with mastercam. Which is fine but I would really like to be able to use intercon.
My reasoning is that with the intercon I can copy and paste different engine bores and angles with a rename and just edit any dimensions as needed on the fly. Say I get a head in that is close to the intake valve seat, I could change the angles,diameters ,stepovers ..etc.
I am not sure what I am looking for, helical interpolation ? I am trying to avoid cad/cam programs but if needed that where I will go.
I am open to all suggestions so fire away how this can be done.
Old time machinist here that only has intercon as cnc training. I have never used cad/cam before as I am sure that is another learning curve.
Thanks in advance.
