A fixture for production machining must be considered like any other machine tool. It should pay for itself from the savings derived from its used. The tool designer may be required to designer the cost of a fixture and whether its construction will be profitable in the early stages of fixture design. The cost and return can not be determined exactly because of the variables that may enter into the overall picture, but a close estimate can be made from formulas developed for this purpose. The economic aspects of the use of a fixture can be considered of the following basic: 1. The production per year necessary to pay out of savings for a fixture of given estimated cost. 2. The maximum allowable cost of a fixture to break even for a given saving in operating cost per price and specific cost given yearly production. 3. The number of years will take to pay ou...
