Mass Finishing, Deburring & Polishing worked example
Spindle Finish Time at 7.2% cycle time allowance: a worked example
This worked example runs the spindle finish time numbers for a tougher week than the baseline: 7.2% cycle time allowance instead of the typical 10%. Calculate spindle finish time for mass finishing, deburring & polishing planning, quoting, troubleshooting, capacity review, or process improvement.
The inputs for this scenario
- Parts to finish on spindle: 120 units (held at the documented default)
- Spindle processing rate: 12 units / hr (held at the documented default)
- Cycle time allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)
Working through the calculation
- The calculation starts from the formula this tool documents: Base spindle finish time time = required work รท processing rate.
- Adjusted run time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
- Base run time works out to 10 hr at these inputs.
- Allowance applied works out to 7.2 % at these inputs.
- Process rate works out to 12 pieces / min at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where cycle time allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
- Use it when scheduling a spindle finishing station or quoting a high-energy deburr, edge-radius, or superfinish job on fixtured parts. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
Results at a glance
- Adjusted run time: 10.72 hr (headline result)
