Quality & Metrology calculator
Inspection Time Calculator
Plan the occupied station time for one inspection batch. Enter a measured repeated cycle, separate batch preparation and documentation, and the reserved time window.
What this calculator does
- Estimate a batch inspection duration from measured work stages and check it against your available station time.
Formula used
- Repeated inspection time = parts × inspection minutes per part
- Preparation and documentation time = setup and handling + documentation
- Required time = repeated inspection time + preparation and documentation time
- Station time margin = available time − required time
Inputs explained
- Parts to Inspect: Required distinct parts from the inspection work order.
- Inspection Time per Part: Observed full repeated cycle, recorded to 0.001 minute.
- Setup and Handling Time: Separate batch preparation, recorded to 0.001 minute.
- Documentation Time: Separate documentation duration, recorded to 0.001 minute.
- Available Station Time: Reserved station window, recorded to 0.001 minute.
How to use the result
- Best suited to inspection station scheduling, batch preparation review.
- Parallel stations, queues and unattended overlap need a separate schedule. A mean cycle does not describe every part or inspection plan.
Current U.S. benchmarks
- U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
Common questions
- Should loading each part be included? Yes. Include repeated loading and unloading in the measured time per part; use setup time only for separate batch preparation.
- Are these labor hours? No. The result is elapsed station time for sequential work. Labor costing requires person-time when several inspectors or unattended steps are involved.
- How do the allowance examples work? They change recorded setup and handling minutes. A lower or higher allowance now represents measurable preparation time rather than an unexplained percentage.
- Does the result include waiting for a gauge? Only if that waiting belongs to the measured cycle or one of the entered batch stages. Unrecorded queues are excluded.
