Hello there Kristiyan.
I think the time you’re going to see is going to vary depending on the shape and then also the features to be machined. Winston has some pretty good videos on this topic that I recommend you check out:
and
In the second video it looks like the total time is 37 minutes. That’s quite conservative, because he’s using a super small endmill that is more fragile, but also wont turn as much material into dust that might be hard to collect.
So if you were to do a simple square and also maybe a simple name engrave, the time might be similar, though could be faster with a larger bit for the cutout, and maybe a v-bit for the name engraving.
Hope this helps!
