From Figure, it can be seen that the FTMS approach provides a significant economy over the historical cost for test case M3941142-1. The notable cost reduction (-39%) obtained with the novel FTMS method in comparison with the traditional tool management is due to the fact that the simulated on-hand inventory level is higher than the Imax limit value for significant time intervals of the tool management period, thus preventing unnecessary dressing operations and tool purchases. The historical trends do not take into consideration the demand rate variation during tool management and CBN grinding wheels keep being sent out for dressing or newly purchased, thus maintaining a high on-hand inventory level that generates superfluous capital investment by seeking excessive stock-out risk protection.
