Assumptions to Review2 notes
- - nitrogen consumption is modeled from flow rate multiplied by active laser and pierce time.
- - Replace the default flow and price with measured flow meter data or your delivered gas contract before quoting.
Estimate gas consumption, gas cost, hourly gas cost, and SCFH flow conversion from flow rate, active cutting minutes, pierce time, purge time, gas price, and delivered gas records.
Best next step
Use this quick gas result as the gas cost input in the full laser cutting cost calculator, then compare gas choice against quality requirements and energy cost per job.
How This Gas Estimate Works
1. Active gas volume
Flow rate is multiplied by active cutting and pierce minutes.
2. Purge volume
Setup purge time is kept separate so changeovers stay visible.
3. Gas cost
Total gas volume is multiplied by delivered gas cost per cubic meter.
What gas consumption changes in a quote
Gas is a small line on some jobs and a major one on others. This result helps an estimator see whether the process choice, run time, or delivery price is shaping that line.
The estimate turns the selected process duration into a gas burden and keeps active cutting separate from preparation or purge work. That separation matters when a short job uses a long setup or purge.
Flow is a property of the qualified process and the supply system, not a universal material constant. Compare the result with cylinder or bulk records before using it to choose between gases.
