Many composite manufacturers will create a nest of all of the plies relating to one kit and then repeatedly cut the same nest as required. This is referred to as static nesting. A major problem is that if you are exclusively static nesting then it's difficult or impossible to use the end of the roll efficiently. If you are cutting several static nests from the same material this will be nowhere near as efficient as if you were to take all of the plies into consideration during nesting.
This process, referred to as dynamic nesting or 'Just in Time nesting', can often generate double-digit percentage savings, with one JETCAM user saving €1500 in the first four hours of using the software due to material efficiency alone. You'll also no longer have the issue of inefficient use of end of rolls, as a dynamic nest can be of any length.
