Mass Finishing, Deburring & Polishing worked example

Media Wear Rate at 99% target maximum wear rate: a worked example

Push target maximum wear rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when media wear rate in mass finishing, deburring and polishing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Media volume lost in cycle: 8 units (unchanged)
  • Starting media volume in machine: 250 units (unchanged)
  • Target maximum wear rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Media Wear Rate rate = affected amount รท total amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for gap to target.
  • At this operating point the engine returns 8 count for affected count.
  • At this operating point the engine returns 250 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum wear rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the fraction of the starting media charge lost in a cycle as a percent, and the gap between that wear and your maximum acceptable wear rate. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Rate: 3.2 % (headline result)
  • Gap to target: 95.8 points
  • Affected count: 8 count
  • Total count: 250 count
