Sci. 31, No. 3, 679-688 (2010).} \itemab Summary: An algorithm is presented for determining the optimal machining parameters for each of a set operations required to produce a product in the economic lot sizing context using a CNC Machine Tool. The cost components considered are: (1) inventory carrying cost; (2) cost of machine and operator time; (3) the cost of tools consumed; and (4) the set up cost for producing each lot. The optimizing criterion is minimum total cost comprising the above components on a unit time basis. It is shown that the optimal machining parameters could be outside what is considered the efficiency range in traditional machining economics. \itemrv{~} \itemcc{} \itemut{machining economics} \itemli{} \end
