Materialeudnyttelse ved strimmeludlægning

Beregn hvor stor en andel af pladestrimlen der bliver til færdigt emne

Ved konstruktion af progressive stanseværktøjer lægges emnerne ud på en strimmel med en fast bredde og fremrykning (pitch). Materialeudnyttelsen er emnearealet i forhold til det strimmelareal, hvert emne 'bruger'. Branchen regner typisk minimum 60 % som acceptabelt og ca. 75 % som et godt mål for et velkonstrueret strimmellayout (strip-layout-litteratur for progressive stanseværktøjer).

AssessmentOver industriens benchmark på ca. 75% — godt strimmellayout.
Waste — discarded goods, surplus material, and incorrectly sorted waste — costs double: both in raw materials and in the energy already spent processing them. Circular economy is about keeping materials in circulation instead of discarding them: reuse of packaging, recycling of metal and plastic chips, and proper sorting so waste can actually be recycled instead of being burned or landfilled. As an operator, it is often you who physically sorts and handles the waste — and it is your habits that determine whether the sorting actually succeeds.16,7 %

Udnyttelsesgrad = emneareal / (stribebredde · fremrykning) × 100%

Eksempel: emneareal 2000 mm², strimmel 60×40 mm ⇒ 2000/2400 ≈ 83,3%
