Stock area record
Remnant and Yield Ledger
Reconcile starting stock against accepted part area, tagged reusable remnant, and waste. Calculate good-part yield without confusing recovered stock area with a material-charge policy.
Content reviewed 2026-11-02. Verify the applicability of each source before using a value in a quote.
Input to record
Net stock, accepted-part, reusable-remnant, and waste areas in mm²; stock identity, material batch, CAM evidence, credit policy, and reviewer.
Output to carry forward
Good-part yield, good plus reusable area, waste ratio, unallocated area, and an exportable ledger. Negative reconciliation is rejected; no material price is inferred.
Area ledger
Use one stock piece or a clearly bounded stock batch. Enter actual net areas in mm² from the same CAM or measured basis. Each region belongs to exactly one category. Hole slugs, kerf, trim, rejects, and skeleton belong in waste unless separately tagged and approved for reuse. For irregular remnants use the usable shape area, not its bounding rectangle.
Enter all four areas, including explicit zero values where appropriate.
Yield is an area ratio. It does not decide the material charge. A shop may charge full stock, credit an approved remnant, or follow customer-owned-stock rules. Do not count remnant area as sold good parts or deduct the same credit twice. No price or credit is inferred here.
Local draft only. Refresh clears inputs; download the record first. A balanced ledger is not a nesting, geometry, cost, or quality approval.

- LaserCalc Pro calculation methodology
Repository methodology: use shop CAM, remnant, scrap, invoice, machine, and completed-job evidence. This is an authored calculation/recording method, not an external inspection standard or parameter benchmark.
- LaserCalc Pro scrap allowance and yield policy
Defines sellable-area yield and the separate shop decision for reusable remnants, material charging, and credits. No public yield target or remnant credit is supplied.

| Record / method | Rule / arithmetic | Shop action | Source | Applicability | Confidence | Reviewed |
|---|---|---|---|---|---|---|
| Stock boundary | Starting area is the measured net stock area for the one piece or batch being reconciled, in mm². | Keep stock ID, grade, thickness, batch, geometry, and CAM/measurement reference together. | LaserCalc Pro methodology — material utilization | Same stock and area basis across every category; no bounding-box substitution for irregular shapes. | Area accuracy depends on the supplied geometry. | 2026-11-02 |
| Area reconciliation | Unallocated = stock − good parts − reusable remnant − waste. Negative remainder is rejected. | Classify each region once. Include kerf, skeleton, rejects, trim, and non-reusable slugs in waste. | LaserCalc Pro authored area-accounting equation | No overlapping categories; a balanced sum does not verify the CAM geometry. | Deterministic arithmetic; classification requires shop review. | 2026-11-02 |
| Good-part yield | Good-part yield = accepted part area ÷ starting stock area × 100. | Do not add reusable remnants to accepted sold-part area. | LaserCalc Pro scrap allowance and yield policy — gross yield | Accepted net part area, after holes and rejected pieces are classified. | Deterministic ratio; acceptance is shop supplied. | 2026-11-02 |
| Material charging | Area yield does not determine a quote charge. Credits require a tagged remnant and the applicable shop/customer policy. | Choose full-stock charge or the approved credit treatment; apply each credit only once. | LaserCalc Pro scrap allowance and yield policy — remnant credit | Invoice, stock policy, customer material rule, and reviewer approval. | No cost or remnant value inferred. | 2026-11-02 |
| Arithmetic example | Stock 1,000,000; good 600,000; remnant 250,000; waste 150,000 mm². Yield = 60%; good + remnant = 85%; remainder = 0. | Replace all values with the actual job record. No target yield is implied. | LaserCalc Pro authored worked arithmetic | Illustrative numbers only; no material, cost, or machine recommendation. | Equation example, not measured performance. | 2026-11-02 |
Reference workflow
- Match the job, material, machine head, and quality requirement to a row.
- Confirm the source, review date, and confidence before copying the value into a quote worksheet.
- Use a measured result or current OEM record when the row is marked as required or unverified.
