Questions on using a moving gantry style mini-mill...

[Davek0974]

On the left side of my part in the OP, there are three slotted holes on the diagonal face.

After roughing the outside with a 5mm tool, these will obviously not be cut, but with my plan to finish-pass the outside with the 2mm tool in one pass, this will mean the 2mm tool taking the full depth cut on these features.

Calculator shows speed for finish pass as 996mm/min as it's only taking 0.1mm off but here it shows speed as 380mm/min as full depth slotting cut.

Options -
run all outside at the slower rate,
run outside as multiple pass contouring at the higher rate,
try and get jiggy with path rules / action points in sheet-cam to slow down in that area,
something else??
