STOCK FIT

Timber end trim volume — stock pieces scenarios.

How does changing stock pieces affect timber end trim volume when the other inputs stay fixed?

What this decision changes

Full required pieces must fit usable stock. Aggregate area or length alone cannot prove a feasible cut or roll allocation. Method basis: Actual dimensions must be supplied. End trim is your cut plan and does not establish defect allowances or structural grading.

The focus is stock pieces. All other shared inputs remain fixed for each evaluated range.

Usable volume = (stock length − 2 × trim) × actual width × actual thickness × countTimber End Trim Volume Calculator

Evaluate your supplied alternatives

Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only stock pieces; the other entered values stay fixed.

Measured plan and product inputs

Purchased length

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Actual width

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Actual thickness

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Read the evaluated results

Look for jumps in purchased stock and rejected fits. The rows show actual evaluated allocations, not an assumption that every intermediate size will behave identically.

Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
Enter a comparison range on the focused input's stated unit and quantity basis.
Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.

Keep the comparison within scope

Permitted orientation, complete-run requirements and reserved cut losses remain supplied inputs; sampled layouts do not promise a globally optimal cut plan.

Dimensions, layouts, rates and material properties are supplied by the user.

Does not select construction specifications or certify safety.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
