Mass Finishing, Deburring & Polishing worked example

Media-To-Part Ratio with number of parts in the load of 50 units: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop number of parts in the load to 50 units, then walk the calculation through step by step. Calculate media-to-part ratio for mass finishing, deburring & polishing planning, quoting, troubleshooting, capacity review, or process improvement.

The inputs for this scenario

  • Number of parts in the load: 50 units (the input this scenario stresses; the baseline uses 100)
  • Media volume per part: 4 units (held at the documented default)
  • Bulk-density / volume conversion factor: 0.01 x (held at the documented default)
  • Process aggressiveness multiplier: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Media-To-Part Ratio = first factor × second factor × conversion factor × process multiplier.
  • Result works out to 1 units at these inputs, and this is the headline figure for the scenario.
  • Base product works out to 1 value at these inputs.
  • Multiplier works out to 1 x at these inputs.
  • Factor A x B works out to 200 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where number of parts in the load sits at 100 units and the headline result is 2 units, this scenario comes in 50% below the baseline at 1 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to number of parts in the load, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes uniform media size and part geometry; nested or magnetic parts, or media that breaks down mid-cycle, will shift the effective ratio.

Results at a glance

  • Result: 1 units (headline result)
  • Base product: 1 value
  • Multiplier: 1 x
  • Factor A x B: 200 value

Run it with your numbers

  • To rerun this with your own numbers, open the live Media-To-Part Ratio calculator, set number of parts in the load to your actual value, and adjust the remaining inputs to match your operation.
