Debulk Cycle Time at 17% debulk setup and handling allowance: a worked example

This scenario runs the debulk cycle time calculation on the strong side: 17% debulk setup and handling allowance, with every other input held at its documented default. planning vacuum debulk time during layup

The inputs for this scenario

  • debulk cycles required: 9 cycles (unchanged)
  • debulk cycle completion pace: 1.8 cycles / hr (unchanged)
  • debulk setup and handling allowance: 17 % (raised for this scenario; the documented default is 15)

Working through the calculation

  • Applying the documented formula (Base debulk cycle time = debulk cycles required รท debulk cycle completion pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 5.85 hr for estimated debulk cycle time, the number this scenario is built around.
  • At this operating point the engine returns 5 hr for base debulk cycle time.
  • At this operating point the engine returns 17 % for debulk setup and handling allowance.
  • At this operating point the engine returns 1.8 cycles / hr for debulk cycle completion pace.

How this compares with the baseline

  • Against the tool's baseline example, where debulk setup and handling allowance sits at 15% and the headline result is 5.75 hr, this scenario comes in 1.74% above the baseline at 5.85 hr.
  • Use it when scheduling a thick-laminate layup, planning tool occupancy, or quoting the labor and time content of a debulk-heavy part. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • estimated debulk cycle time: 5.85 hr (headline result)
  • base debulk cycle time: 5 hr
  • debulk setup and handling allowance: 17 %
  • debulk cycle completion pace: 1.8 cycles / hr
