The experiments,however, being in line with advancementand progress in the state of the art ofnonferrous foundry practice, are inter-esting in that they apparently closelycheck the claims made by manufact-urers of furnaces and those investiga-tors of electric melting who have pub-lished their results. The fact that non-ferrous castings of 40,000 differentparts are ordered from the foundryduring tho normal year, of which ap-proximately 10 per cent are ordered inlarge quantities, necessitates carefulplanning and close adherence to theplans, in order to insure delivery of thecastings when required. How Production Schedule is Planned The basis for this planning is a sched-ule issued each half year. This scheduleconsists of quantities of units, the quan-.

From this schedule, which isin terms of product units, a plan is laidout to cover the manufacture of each ofthe parts entering into these units, ineach of the various departments imwhich work is performed on them. Thisplan is received in the brass foundry bya despatch clerk, who is the represent-ative of the production bureau, a partof the executive organization which con-trols and plans production throughoutthe plant. The dispatch clerk immediate-ly enters requisitions for the manu-facture of cores, based on the actualworking time to produce them and toinsure their delivery a day in advanceof the date upon which it _will be nec-essary to start the actual moulding inorder to meet the plan. The mouldingdate is calculated from the actual manhours required to produce the quantityof cast
