) Calculate Lead Time Flint Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of 80 parts. A part requires 4 minutes in milling and 7 minutes in nishing. The move time between the two'operations for a complete batch is 8 minutes. Under the lean philosophy, the part is produced in a cell that fncludes both the milling and rshing'operations. The operating time is unchanged; however, the batch' size is reduced to 4 parts and the move time is eliminated. \\ Determine the valueadded, non-value-added, and total lead times, and the valueadded ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place.
