Machining Cost Optimization Involving Shift and Overtime Work

Abstract

Minimization of machining cost as a function of cutting speed is examined taking into account the effect of shift and overtime work. The cost minimization problem is formulated as the minimization of the total cost of machining a given number of workpieces within a given time. Different types of costs of machining and determination of cost parameters in the long run and short run are discussed. The use of both one-tool type and several-tool types is considered. Characteristics of the solutions of the problem are examined in light of examples. [S1087-1357(00)02304-2]
