Tool Sharpening, Reconditioning & Industrial Repair Services worked example

Coating Batch Size at 99% pvd chamber uptime: a worked example

This scenario runs the coating batch size calculation on the strong side: 99% pvd chamber uptime, with every other input held at its documented default. Use it when coating batch size in tool sharpening, reconditioning and industrial repair services is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Tools loaded per coating run: 4 units / cycle (unchanged)
  • Coating runs available in the period: 480 cycles (unchanged)
  • PVD chamber uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass coating yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross coating batch size capacity = units per cycle × available cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross capacity.
  • At this operating point the engine returns 19.2 units for uptime loss.
  • At this operating point the engine returns 57.02 units for yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where pvd chamber uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when planning coating throughput for a shift, week, or campaign, or when deciding whether to add runs to hit a delivery number. 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

  • Good output capacity: 1,844 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 19.2 units
  • Yield loss: 57.02 units

Run it with your numbers

  • Every input above is editable in the live Coating Batch Size calculator, which recalculates instantly and can be shared with the inputs intact.
