Aerospace & Defense Manufacturing calculator
CMM Inspection Capacity Calculator
CMM capacity is often a constraint for tight-tolerance aerospace components with dense GD&T and required inspection records. This calculator estimates accepted inspection output so quality planners can see whether CMM availability supports production and FAIR schedules.
What this calculator does
- Estimate accepted CMM inspection capacity from features per program cycle, available CMM cycles, uptime, and first-pass inspection yield.
- a quality planner needs to check whether available CMM time can support an aerospace inspection queue
- Returns estimated accepted CMM checks or part inspections in a planning window.
Formula used
- Gross CMM capacity = checks per cycle × available CMM cycles
- Accepted CMM inspection capacity = gross capacity × CMM uptime × accepted inspection yield
Inputs explained
- CMM checks per program cycle: undefined
- Available CMM program cycles: undefined
- CMM uptime: undefined
- Accepted inspection yield: undefined
How to use the result
- Use it for bottleneck review, first article planning, production release, or outsourcing inspection decisions.
- It does not account for specific program runtime, fixture changes, probe qualification, manual layout, or programmer availability unless reflected in the inputs.
Common questions
- What information do I need for CMM inspection capacity? You need CMM checks per cycle, available cycles, expected uptime, and accepted inspection yield.
- Which units should I use for CMM inspection capacity? Use the units shown beside each field and keep the same lot, contract, or planning period throughout the calculation. Convert minutes to hours, pounds to kilograms, dollars per part to dollars per lot, or counts to lots before entering mixed data.
- What does the CMM inspection capacity result tell me? It estimates how much accepted CMM inspection output is available.
- When is this CMM inspection capacity estimate only approximate? Use it to add shifts, outsource inspection, resequence lots, reserve FAIR time, or reduce inspection bottlenecks.
