Mapping Cycle time calculation Topic Title: Cycle time calculation Topic Summary: Created On: 05/01/2006 12:00 AM Linear : Threading Send to a Friend Search Topic Keyword Topic Tools View similar topics Print this topic. 05/01/2006 02:49 PM 99919 Micky Mekosch We are drawing up a value stream map. The first machine in our process feeds two identical lines. There is one part produced on these two lines. We needed to add the second line because we could not keep up with demand. The cycle time for the first machine (that feeds both lines) is 7.5 seconds. Then it is 30, 25, 17, and 37 seconds for each subsequent machine on each line. How should the cycle time be noted on the value stream map? Should we be be doubling any of these numbers? Our takt time is 17.7 seconds. 05/16/2006 12:52 PM Jay_Michaels Jay Michaels based on the information that you provided, I will assume that all subsequent operations, after the first machine, are duplicated. If this is the case, the machine with a cycle time of 37 seconds paces your line. Since you have two on these machines, the line (in it's entirety) produces a part every 18.5 seconds (37/2). If you takt time is 17.7 seconds, I would susspect that you are running some overtime, even with the second line. NOTE: you may be able to get by with only one machine #4 (17 second cycle) if the material can flow into and out of it.
