Interesting. Till now there is no short-cut method to quote for machining parts. It really requires years of experience to know the processes involved to make any parts before quoting. Ofcourse we do face problems from rookie half-cook quoters who give crazy under-quotes for machining parts, eventually killing their employers and the trade, before fleeing to other trades. Just rantling.
Generally quotes starts from material prices, then you add on the individual process costs based on complexities involved and in the end add a margin to keep you running. IMHO
