How Negative-Stiffness Vibration Isolation Improves CMM Performance in Precision Surface Measurement

When built into inspection equipment, like a coordinate measuring machine, a laser interferometer system reports the surface condition of a product with more accuracy than any other method.  Such a precision laser-position measurement system allows users to improve product quality and reliability, and increase manufacturing consistency and production yields.
High-throughput CMM laser interferometry surface measurement systems  can be negatively affected by plant low-frequency vibrations, which can distort the interferometry measurements and deliver inaccurate readings. Here's how to prevent that from happening.

How Things Are Measured Today

A former hurdle with laser scanning was difficulty scanning highly reflective surfaces. This would necessitate spraying the object with a matte spray coating to eliminate obtaining reflective data and other extraneous noise. Modern laser scanners feature automatic real-time adjustment of sensor settings for each individual point along the laser stripe, effectively handling highly reflective surfaces or those with varying colors.
Retrofitting CMMs or articulated arms with new laser scanners is one affordable option among many that shops are considering.

True Position Measurement

Inspection of a bore in an open setup often requires multiple measurement steps and mathematical calculations, but portable CMM technology from FARO can alleviate much of this work by allowing the user to fix the part in one spot, take several points to create an alignment of X- and Y-axes, and measure the bore. Software then determines the position of the bore and its deviation from the called out position.
