A simple volume milling seq. time took to generate about 3 mins.
rgh and finish in this op 6061 al.
Ill try to explain in under one page
In Pro e volume milling is creating a solid mass around features on reference part that you want to machine puting excess material before the reference part using any shapes to create the mass then trimming volume to reference part leave more or less excess to decide on how many passes are need to rough to the part and after roughing is done there are parameters to finish all in one sequence.
