Re: machine billing rate
It depends on what exactly you're doing. If you're running the same part day after day doubling the cost doesn't really make sense. Production runs tend to have a moderate to high start up cost, but the repeat work typically allows for low cost on the final product.
Now, if you're constantly tearing down and setting up to run one off's, it makes sense to double the price, because there's typically a fair amount of set up time, part programming and debug, etc. Not to mention the added cost of having to build custom hold down tooling when necessary.
