3D Or Three-Axis Calibration: What's The Difference?

Guarding against errors in the volumetric positioning of a machine tool is critical to machining contours and other 3D surfaces accurately. There are two accepted methods for 3D (volumetric) calibration, including the “body diagonal displacement method” and the proprietary “sequential step diagonal measurement method.” This second technique, developed by Optodyne, is said to protect against displacement errors, straightness errors, squareness errors and angular errors.
