Prediction of Optimum Tool Life and Cutting Parameters by Comparative Study of Minimum Cost Criterion and Maximum Production Rate Criterion
摘要
In the Economics of machining three criterions are commonly used: Minimum cost criterion, Maximum production rate criterion and Maximum profit rate criterion. In this paper emphasis has been given to former two criterions as economics are highly related to cost of production and rate of production. The comparison has been made between these two criterions on the basis of tool life which has been calculated using optimum values of cutting speed and feed rate in extended Taylor’s tool life equation with predetermined value of depth of cut.
