Abstract

This paper examine how the applications of Just-in-Time (JIT) manufacturing philosophy create excess capacity if the rate of production in a machining center is greater than the rate of the demand for the products at a subsequent machining center. The excess machining capacity created can be reduced by operating the machine(s) with excess capacity at a lower speed up to a certain limit (in order to maintain efficiency). By operating the machine(s) with excess capacity at a lower speed, the machine utilization is increased as well as the tool life of the machine(s).
