Calculate Lead Time sizes of 50 parts. A part requires 2 minutes in milling and 6 minutes in finishing. The move time between the two operations for a complete batch is 7 minutes. eliminated. Feedback V Check My Work Recall that lead time can be classified as one of the following: 1. Value-added lead time, which is the time spent in converting raw materials into a finished unit of product. 2. Non-value-added lead time, which is the time spent while the unit of product is waiting to enter the next production process or is moved from one process to another. In this exercise for Traditional: Value-added processing time \\( = \\) Milling time + Finishing time Non-value-added time \\( = \\) Total within-batch wait time + Move time, where Total Within-Batch Wait Time \\( =( \\) Total Time to Perform Operations) \\( \\times( \\) Batch Size -1\\( ) \\) Add value-added processing time + non-value-added processing time to obtain total processing time. Calculate Value-Added Ratio \\( = \\) Value-Added Process Time \\( \\div \\) Total Process Time In this exercise for Lean Manufacturing: Value-added processing time \\( = \\) Milling time + Finishing time There is no move time. Add value-added processing time + non-value-added processing time to obtain total processing time. Calculate Value-Added Ratio \\( = \\) Value-Added Process Time \\( \\div \\) Total Process Time Learning Objective 1
