In manufacturing automotive industrial components, the reduction of machining time and operation spare time detected in the cutting operations can be realized by the modification of technological parameters. However, reduction in the total component manufacturing lead time can be realized to a great extent by re-organization of the production process to eliminate unnecessary waiting periods (e.g. storage, in-process storage, etc.). In our study the total lead times of two different types of components were analyzed by mapping the process in a detailed way. The rate of waiting time within the lead time was analyzed; the theoretical and the measured lead times were compared and the effect of operation sequence on lead time was analyzed. Using these calculations and also measurements the problematic operations were identified and suggestions for process improvement were made.
