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 90 parts. A part requires 5 minutes in milling and 8 minutes in finishing. The move time between the two operations for a complete batch is 9 minutes. Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to 6 parts and the move time is eliminated. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place.

The setup requires changing the type of fixture that holds a part. The average setup time has been 135 minutes, consisting of the Following steps: Turn off machine and remove fixture from lathe 10 minutes Go to tool room with fixture 15 Record replacement of fixture to tool room 18 Return to lathe 20 Clean lathe 15 Return to tool room 20 Record Withdrawal of new fixture from tool room 12 Return to lathe 15 Install new xture and turn on machine 10 Total setup time 135 minutes 3. Why should management be concerned about improving setup time? Along ' \\/ setup will result in a large ' V production batch, which increases ' v' work in process inventory and increases ' J lead time. Large ' v' work in process inventory commits working capital that could be used for other purposes. Long lead times decrease ' v/ the company's ability to respond to changes in customer demand. b. Which of the followmg are the ways to improve Hammond Inc.'s setup time? limit the trips to the tool room to one round trip, rather than two. change the location of the fixtures to reduce lathe setup time. eliminate the tool room and instead locate the tools in a visible location near the lathe. change the entire lathe room layout, so that fewer steps are required to turn the lathe on and off, as well as clean the lathe and change fixtures for the lathe. . All of these are ways to improve setup time. \"351057!\" e VJ c. How much time would be required for a setup, using your suggestion in (b)? 35:] minutes
