Laser System Utilization at 92% beam-on utilization target: a worked example

This scenario runs the laser system utilization calculation on the strong side: 92% beam-on utilization target, with every other input held at its documented default. Use this when tracking OEE for a laser cell, justifying a second shift or additional laser system, or identifying whether downtime, changeovers, or scheduling gaps are limiting output.

The inputs for this scenario

  • Actual beam-on production hours: 265 hours (unchanged)
  • Total available hours in period: 352 hours (unchanged)
  • Beam-on utilization target: 92 % (raised for this scenario; the documented default is 80)

Working through the calculation

  • Applying the documented formula (Laser utilization rate = beam-on hours / total available hours x 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 75.28 % for laser system utilization rate, the number this scenario is built around.
  • At this operating point the engine returns 16.72 points for gap to utilization target.
  • At this operating point the engine returns 265 count for beam-on production hours.
  • At this operating point the engine returns 352 count for total available hours.

How this compares with the baseline

  • Against the tool's baseline example, where beam-on utilization target sits at 80% and the headline result is 75.28 %, this scenario lands almost exactly on the baseline at 75.28 %.
  • Use it in periodic asset reviews, capacity planning, or before committing capital to a second laser, to confirm the existing system is genuinely saturated. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
