Composites, Fiberglass & Advanced Materials calculator
Trim Scrap Cost Calculator
Use this calculator to quantify value lost in edge trim, cutouts, flash, tab removal, oversize blanks, and rejected trimmed parts.
What this calculator does
- Estimate cost of cured composite trim scrap from routers, waterjet, saw, or hand trimming.
- pricing cured laminate trim scrap in composite production
- The result estimates cost tied to cured trim scrap for the selected production scope.
Formula used
- Variable trim scrap cost = trim scrap weight or area × trim scrap material value × trim scrap scope included
- Total trim scrap cost = variable trim scrap cost + trim scrap handling and disposal cost
Inputs explained
- trim scrap weight or area: Use weighed cured laminate scrap, trim strip area, cutout weight, or router waste from the work order.
- trim scrap material value: Use material and process value in the cured laminate, not just raw resin or fiber cost, when appropriate.
- trim scrap scope included: Use 100% for all trim scrap in scope or less for one part family, mold, operation, or shift.
- trim scrap handling and disposal cost: Include collection, dust control, disposal, recycling, and MRB handling if rejected parts are included.
How to use the result
- Use it to justify net-shape improvements, nesting changes, trim fixture updates, or CNC path optimization.
- Treat the result as a planning estimate until it is checked against the approved laminate schedule, material datasheets, ply books, resin batch records, tool condition, cure logs, inspection results, customer specification, and actual shop observations for the same part family and process.
Common questions
- What is the trim scrap cost calculator for? Use this calculator to quantify value lost in edge trim, cutouts, flash, tab removal, oversize blanks, and rejected trimmed parts.
- What information should I enter? Enter trim scrap weight or area, trim scrap material value, the included scope percentage, and any fixed tooling, setup, freight, qualification, or engineering cost assigned to the estimate.
- What does the result tell me? The result estimates cost tied to cured trim scrap for the selected production scope.
- When is the result only an estimate? Treat the result as a planning estimate until it is checked against the approved laminate schedule, material datasheets, ply books, resin batch records, tool condition, cure logs, inspection results, customer specification, and actual shop observations for the same part family and process.
