Hey all,
love the forums, great resource. I need some help determining feed and speeds for cutting some rather thin metals -> 0.125-0.375" in crs and alum. (Not at the same time HA HA HA). I have a range of cutters from 0.0625-0.5". They all seem to break at first cut or right after the first few cuts. coolant spray is left to the user, pump is shot.
Example: pocket cutting 0.125 al. with a 4 flute 0.5" and it breaks after 3 passes. Im using FeatureCam7 to model and generate code, it set the f/s @ 5200rpm and ~50ipm. Any help would be appreciated.
