Steve and Hirundin, thank you. This the kind of information I'm trying to get.

Steve, (or anyone)......any chance you can give me a ballpark on time with the following criteria.....

1...Assume that all the moulds will need to finish with incremental passes of .015" steps with a .5 inch carbide ball mill. In other words 260 passes to cover the 4 inches width by the 16 inch legnth.

Hogging....I'm removing I.5 cubic inch of material per lineal inch with a roughing mill. Or about 180 cubic inches per 120" mould. Or 24 cubic inches per 16". Probably no more then a dozen passes. I don't think that is major time unless you tell me otherwise.

2.....in 6061 aluminum.....mild steel....4130....316ss.

What is your best guess per 16" legnth? Your answer is half the decision.
