Hello,

We are considering a new machine to produce small aluminum molds, either a Makino F5+Koma 4th axis rotary or a Mazak VCU 400-5X 5-axis.
My questions is not on the machine, but on programming 3+2 vs. simultaneous and which will achieve a better surface quality.
Both machines have 20k HSK spindles. Accuracy of the Makino is tighter then the Mazak.

Anyone have experience with improved surface quality from simultaneous 4 or 5 axis programming vs. 3+2 positional programming?
