    Error-proofing is a method of 100 percent inspection at the source rather than down the line. In essence error-proofing improves the predictability of the resultant part of the manufacturing process. Therefore the actual inspection time which is non-value added time in the process is reduced. Each process hand-off must be a perfect product

    alchemy- You may be able to find a small CNC mill for around 4000- 5000 but they are expensive (and heavy) pieces of equipment. One of these mills will usually only have three axis movement and you may need to buy all of the computer hardware and software separately. You may want to consider leasing a CNC mill.
