Understanding Accuracy Across the Work Envelope
Machine tool performance is not always uniform across the entire work envelope. Small positioning and geometric errors can compound as the tool moves through different locations, affecting finished-part accuracy in ways that limited checks may not reveal. Volumetric Error Compensation (VEC) provides a more complete understanding of machine behavior by mapping errors throughout the working volume and supplying the data needed to improve overall performance.
Capturing Volumetric Measurement Data
In this video, API’s Active Target and Radian Pro Laser Tracker work together to collect volumetric measurement data. Using Freeform point capture, the Active Target is moved throughout the machine’s working volume while the Radian Pro precisely tracks its position. The resulting measurements reveal deviations across the workspace and provide the foundation for creating an accurate volumetric error map and compensation values.
Turning Measurement Data into Better Performance
With a clearer picture of how the machine performs throughout its work envelope, manufacturers can identify and compensate for inaccuracies that might otherwise go undetected. This can improve positioning accuracy, reduce rework, and support more consistent part production. Watch API’s Volumetric Error Compensation demonstration to see how precision measurement technology can take machine tool performance to the next level.
