Tool Sharpening, Reconditioning & Industrial Repair Services worked example

Edge Prep Time at 12% fixturing & inspection allowance: a worked example

This scenario runs the edge prep time calculation on the strong side: 12% fixturing & inspection allowance, with every other input held at its documented default. Use it when edge prep 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

  • Cutting edges to prep this batch: 120 units (unchanged)
  • Edges honed per hour on the edge-prep station: 12 units / hr (unchanged)
  • Fixturing & inspection allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base edge prep 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 fixturing & inspection 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 scheduling the edge-prep cell, quoting reconditioning lead time, or checking whether one hone station can keep up with the grind department's output. 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)
