Milling a Closely Matching Forged Blank versus Other Methods

    It has been a long but very poductive day. Today I discussed two procedures with machine tool vendors for making frames in the new gun plant. One method is to mill a cloely matching forging versus another method that is to use a water jet to cut bulk material from a blank, followed by milling.

    Closely matching forgngs are typically used to lower the macine time, but do requir forgew die development and forging equipment. The latter method can use non-forged blanks (provided requirements in strength are met), bring cycle time down with the water jet, and keep the cycle times low.

    If strength becomes an issue with the latter method single crystal cast material can be used. or a non-directional forged blank. Both methods will likely be used to allow splitting of method to occur between calibers.

    In another area of the gun plant I am excited that for the vast majorityof the plant we can employ "lights out" manufacturing. In the lights out area labor count falls to virtually zero. While this level of automatin comes at a cost, it will allow us to sustain the operation in an America where finding employees who are functionally literate is becoming difficult. Sorry foks, there is no requirement that I learn to communicate in Spanish or Ebonics, much less teach someone to read clearly written English instructions.

    Indeed. The up-front labour costs for using automation must surely be offset by the longer term cost of employing actual humans, for whom you'd have to pay into the sorry joke of a retirement "pension" known as Social Security, much less medical and dental benefits.

    And fie on the thought of costly job education subsidization! And no better dream can be realized than saving on those human worker related parts of OSHA compliance and incidental insurance for some local inbred hicks you'd otherwise be forced to hire, assuming that you didn't outsource your production to West Africa.

    But then you'd be in competition with the Red Chinese government for that labour market.
