How do I calculate ROI on building a dedicated fixture?

Fixture ROI compares the fully-loaded build cost against the machine time saved per part times annual volume. If a fixture costs 3,200 dollars to build and saves 4 minutes of setup and cycle time across 8,000 parts a year at your machine rate, it pays back in weeks. Use Workholding Payback for the timeline and confirm Fixture Utilization is high enough that the savings actually accrue rather than sitting idle in the crib.

When does a multi-part fixture or tombstone pay off?

A tombstone or pallet fixture pays off when spindle utilization gain outweighs the higher Gauge Build Cost and Jig Build Cost. Loading eight parts per cycle cuts load-unload interruptions and lets the machine run lights-out longer. Workholding Automation Payback compares the fixture and automation cost against reclaimed spindle hours. The break-even usually hinges on volume and how much of the cycle is currently lost to manual load, changeover, and re-indicating.

How do I measure whether a fixture is actually being used?

Fixture Utilization divides the hours a fixture is in productive use by the hours it is available, exposing fixtures that were justified on projected volume that never materialized. A dedicated fixture below roughly 30 percent utilization rarely returns its Fixture Lifecycle Cost, which includes storage, maintenance, and periodic recertification. Pair it with Fixture Storage Cost, since low-use fixtures still consume crib space and get counted in Fixture Inventory Accuracy checks.

How does gauge repeatability affect my inspection fixtures?

Gauge Repeatability Score reflects the repeatability portion of a Gauge R&R study, the variation when one operator measures the same part repeatedly on your fixture. A well-designed inspection or CMM fixture with solid locators and a clear datum scheme drives repeatability down, so more of your tolerance band is available for real part variation. If a go/no-go or CMM fixture consumes more than 10 percent of tolerance in R&R, redesign the locating scheme before trusting its results.

Should I standardize fixtures across similar parts?

Fixture Standardization Savings compares the cost of many part-specific fixtures against fewer modular or family fixtures with common bases and swappable locators. Standardizing cuts Fixture Design Workload, Fixture Maintenance Cost, and storage, and it shortens Fixture Changeover Time because setups become familiar. The savings grow with part-family count, so a shop running dozens of similar brackets on shared baseplates usually recovers the standardization effort faster than one running unrelated one-off jobs.

How do I plan for fixture repair and availability?

Fixture Repair Exposure estimates downtime and cost risk from worn locators, damaged clamps, or drifting datums on fixtures your schedule depends on. Gauge Availability Risk flags when a single inspection fixture or go/no-go gauge gates a running job with no backup. Combine both with Fixture Maintenance Cost to decide where a spare or scheduled refurbishment is cheaper than an emergency line stoppage, and keep Fixture Inventory Accuracy high so nothing goes missing mid-run.
