Aktürk, M. S.Avcı, S.2016-02-082016-02-0819960268-3768http://hdl.handle.net/11693/25811In view of the high investment and tooling cost of a CNC machining centre, the cutting and idle times should be optimised by considering the tool consumption and the non-machining time cost components. In this paper, we propose a detailed mathematical model for the operation of a CNC machine tool which includes the system characterisation, the cutting conditions and tool life relationship, and related constraints. This new module will be a part of an overall computer-aided process planning system to improve the system effectiveness and to provide consistent process plans. A hierarchical approach is presented for finding tool-operation assignments, machining conditions, appropriate tool magazine organisation and an operations sequence which results in the minimum production cost. © 1996 Springer-Verlag London Limited.EnglishCNCMachining parametersMathematical programmingOptimisationProcess planningTool allocationCharacterisationCNC machine toolsCnc machiningComputer-aided processCutting conditionsHierarchical approachIdle timeIntegrated processMachining conditionsMachining parametersMachining timeOptimisationsProcess planProduction costSystem effectivenessTool allocationTool lifeTool magazineTooling costsComputer aided manufacturingComputer control systemsEquipmentMachine toolsMachineryMachiningMachining centersMathematical modelsMathematical programmingProcess controlProcess engineeringComputer aided process planningArticle10.1007/BF01351201
