Assist-Gas Cost Comparison
Compare caller-supplied assist-gas consumption and rework costs.
Description
Assist-gas cost comparison adds consumption cost and rework cost for each option.
Assist-gas cost comparison adds consumption cost and rework cost for each option. Comparable currencies and gas-volume units are required.1
Compare caller-supplied assist-gas consumption and rework costs.
When to use Assist-Gas Cost Comparison
Use this tool to compare caller-supplied assist-gas consumption and rework costs.
Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
How to use Assist-Gas Cost Comparison and understand its results
- Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
- Enter nitrogenFlowUnitsPerHour, nitrogenUnitCost, nitrogenCutHours, oxygenFlowUnitsPerHour, oxygenUnitCost, oxygenCutHours, nitrogenReworkCost, oxygenReworkCost using the field table and calculation rules, then run the tool.
- Read nitrogenTotalCost, oxygenTotalCost, costDifference, lowerCostGas. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| nitrogenFlowUnitsPerHour | Nitrogen flow | number; minimum: 0 | Required |
| nitrogenUnitCost | Nitrogen unit cost | number; minimum: 0 | Required |
| nitrogenCutHours | Nitrogen cutting time (h) | number; minimum: 0 | Required |
| oxygenFlowUnitsPerHour | Oxygen flow | number; minimum: 0 | Required |
| oxygenUnitCost | Oxygen unit cost | number; minimum: 0 | Required |
| oxygenCutHours | Oxygen cutting time (h) | number; minimum: 0 | Required |
| nitrogenReworkCost | Nitrogen rework cost | number; minimum: 0 | Required |
| oxygenReworkCost | Oxygen rework cost | number; minimum: 0 | Required |
Enter nonnegative rates, prices, times and rework costs. Return totals, signed difference and lower-cost gas, with exact equality labeled tie.
total=flow×unitCost×hours+rework; difference=oxygen−nitrogen Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| nitrogenTotalCost | Nitrogen scenario cost | number; minimum: 0 |
| oxygenTotalCost | Oxygen scenario cost | number; minimum: 0 |
| costDifference | Oxygen minus nitrogen cost | number |
| lowerCostGas | Lower-cost scenario | string; one of "nitrogen", "oxygen", "tie" |

}Limitations and assumptions
No gas prices, process quality, facility overhead or technical gas suitability is estimated.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Ablation Sampling Area: Estimate gross and nonoverlapping area sampled by a sequence of ablation pulses. For a complementary task, use Brightness Conservation: Measure brightness retention through a tapered double-clad section against a caller limit.
