Mass Finishing, Deburring & Polishing worked example
Media Wear Rate at 68% target maximum wear rate: a worked example
Suppose target maximum wear rate falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate media wear rate for mass finishing, deburring & polishing planning, quoting, troubleshooting, capacity review, or process improvement.
The inputs for this scenario
- Media volume lost in cycle: 8 units (held at the documented default)
- Starting media volume in machine: 250 units (held at the documented default)
- Target maximum wear rate: 68 % (the input this scenario stresses; the baseline uses 95)
Working through the calculation
- The calculation starts from the formula this tool documents: Media Wear Rate rate = affected amount รท total amount.
- Rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
- Gap to target works out to 64.8 points at these inputs.
- Affected count works out to 8 count at these inputs.
- Total count works out to 250 count at these inputs.
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. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
Results at a glance
- Rate: 3.2 % (headline result)
- Gap to target: 64.8 points
- Affected count: 8 count
- Total count: 250 count
Run it with your numbers
- To rerun this with your own numbers, open the live Media Wear Rate calculator, set target maximum wear rate to your actual value, and adjust the remaining inputs to match your operation.
