How an Offcut Differs From Scrap on a Repeat Job
An offcut still fits another part of the same stock. A strip too narrow to nest is scrap. Measure the leftover before the next job.
Yield
How many finished pieces remain after kerf, trim, and the leftover that cannot be used.
How a Bar, Pipe, or Extrusion Wastes Length Instead of Sheet Area
Count saw cutoff and the leftover bar end on a linear cut list. A sheet nest is a different yield. Do not reuse one waste percent.
What trim, the skeleton, and the edge margin cost on a sheet
The edge margin, the web between parts, and the leftover frame still cost the sheet. Count them on the nest before quoting the batch.
How many finished pieces a sheet still yields after the kerf is counted
Each cut between parts takes a strip. Count slots, skeleton, and unused border before quoting how many finished pieces one sheet can give.
How nesting changes yield when parts cannot spin freely
Lock grain, brush, and bend direction before comparing two nests. A layout that looks full can still be illegal on the sheet you bought.
