Saw Cut Yield with starting raw stock length or blank count of 120 units: a worked example

This worked example runs the saw cut yield numbers for a tougher week than the baseline: starting raw stock length or blank count of 120 units instead of the typical 240 units. Estimate saw-cut yield after kerf, trim, and remnant deductions are subtracted from starting bar, tube, plate, or billet stock.

The inputs for this scenario

  • starting raw stock length or blank count: 120 units (the input this scenario stresses; the baseline uses 240)
  • saw kerf loss: 8 units (held at the documented default)
  • trim, facing, and test-piece loss: 6 units (held at the documented default)
  • unusable remnant allowance: 10 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total saw-cut losses = saw kerf loss + trim, facing, and test-piece loss + unusable remnant allowance.
  • usable saw-cut stock works out to 96 usable units at these inputs, and this is the headline figure for the scenario.
  • total saw-cut losses works out to 24 value at these inputs.
  • starting raw stock length or blank count works out to 120 value at these inputs.
  • Utilization works out to 80 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where starting raw stock length or blank count sits at 240 units and the headline result is 216 usable units, this scenario comes in 55.56% below the baseline at 96 usable units.
  • Use it when ordering raw stock for a sawing job, costing material per part, or comparing blade or cut-plan options for waste. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • usable saw-cut stock: 96 usable units (headline result)
  • total saw-cut losses: 24 value
  • starting raw stock length or blank count: 120 value
  • Utilization: 80 %
