Tool Sharpening, Reconditioning & Industrial Repair Services worked example

Flute Grind Time at 12% wheel dress & setup allowance: a worked example

This scenario runs the flute grind time calculation on the strong side: 12% wheel dress & setup allowance, with every other input held at its documented default. Use it when flute grind time in tool sharpening, reconditioning and industrial repair services is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Flutes to regrind this batch: 120 units (unchanged)
  • Flutes ground per hour on the CNC grinder: 12 units / hr (unchanged)
  • Wheel dress & setup allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base flute grind 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 wheel dress & setup allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when loading the CNC grinder, quoting regrind turnaround, or checking grinder capacity against incoming volume. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Adjusted run time: 11.2 hr (headline result)
