Mass Finishing, Deburring & Polishing worked example

Bowl Load Capacity at 99% bowl uptime: a worked example

What does the result look like when bowl uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when bowl load capacity in mass finishing, deburring and polishing is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Parts finished per bowl cycle: 4 units / cycle (unchanged)
  • Available finishing cycles: 480 cycles (unchanged)
  • Bowl uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass finish yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross bowl load capacity capacity = units per cycle × available cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross capacity.
  • At this operating point the engine returns 19.2 units for uptime loss.
  • At this operating point the engine returns 57.02 units for yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where bowl uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when bowl uptime is genuinely sustained, not just peaked for a shift. It treats uptime and yield as flat percentages; in reality both vary with part mix, media condition, and operator load/unload pace.

Results at a glance

  • Good output capacity: 1,844 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 19.2 units
  • Yield loss: 57.02 units
