Computer Optimization of Machining Conditions for Shop Production

Two computer methods for industrial optimization of machining conditions are described and demonstrated. The performance index method requires only shop data for machining time, number of pieces produced, and number of tool changes. The production optimization method requires tool life, time, and cost data. Both are designed to refine the initial data input with shop test data obtained during normal production, as related to one or more of three production objectives: minimum unit cost, maximum production rate and maximum profit rate. The computer programs are constructed for use by shop personnel with little knowledge of mathematics or computers. Both methods are rapid and economical, and the programs can be processed by either in-plant or remote computer facilities. The user is given all information needed to install the programs and adapt them to his purposes.
