Mass Finishing, Deburring & Polishing worked example

Drying Time at 12% drying time safety allowance: a worked example

What does the result look like when drying time safety allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when drying time in mass finishing, deburring and polishing is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Parts to dry this batch: 120 units (unchanged)
  • Dryer throughput rate: 12 units / hr (unchanged)
  • Drying time safety allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base drying time time = required work รท processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for adjusted run time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base run time.
  • At this operating point the engine returns 12 % for allowance applied.
  • At this operating point the engine returns 12 pieces / min for process rate.

How this compares with the baseline

  • Against the tool's baseline example, where drying time safety allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when drying time safety allowance is genuinely sustained, not just peaked for a shift. It assumes one steady throughput rate; drying slows for heavy, blind-hole, or nested geometries that trap water, so verify the rate against your worst-case part.

Results at a glance

  • Adjusted run time: 11.2 hr (headline result)
  • Base run time: 10 hr
  • Allowance applied: 12 %
  • Process rate: 12 pieces / min
