Metrology fixture tables are used in manufacturing facilities to fixture parts or hold a coordinate measuring machine or other measuring devices so tooling fixtures or manufactured components can be accurately measured, modified, or inspected. The portability of fixture tables is handy, allowing easier access to the CMM and the object being measured.
What Is Metrology?
Metrology is defined as “the scientific study of measurement.” In manufacturing processes, tooling fixtures, along with products, components and parts that are produced, need to conform to very specific, precise measurements.
What Are the Benefits of Using Fixture Tables?
Some plants have a designated permanent area for measuring and inspecting parts. While this setup keeps everything in one place, it can be inconvenient as well. Fixture tables allow flexibility:
Using a self-contained portable fixture table can allow these tasks to be performed close to the line without needing to take the objects to be measured across the facility.
The bottom shelf can hold supplies, components, equipment, and workpieces conveniently.
Fixture tables have several features to ensure precise measurements:
They are constructed to be very stable and able to hold significant weight. The slightest movement can skew the accuracy when measuring an object.
Fixture plates provide various ways to secure both your measuring equipment and the object being measured. Precision bored holes form grids, and the number, size and spacing of these holes can be customized. Mounting holes for CMM devices can be added, correctly positioned for the specific model being used.
Both the X and Y axes are marked with numbers and letters.
Some fixture tables have locking wheels to prevent movement.
Fixture tables are available in different sizes to accommodate a company’s specific needs.
