In-process optical measurement and compensation of machine tool thermal deformations

June 9, 2026
Author(s)
Zongze Li, Aaron Cornelius, Gonzalo Reyes, Edward Kinzel, Ryuta Sato, Gregory Vogl, Robert Landers
Machine tool deformations due to thermal loads from motors and part processing, as well as from changing ambient temperature, can dominate the machine tool's volumetric error and substantially affect part quality. Current methods struggle to take

Vibrometer-based Measurement of Turned Diameters

November 3, 2025
Author(s)
Aaron Cornelius, Osian Leahy, Burak Sencer, Gregory Vogl
Producing high-accuracy machined diameters requires the ability to check the part accuracy inside the machine tool so that process corrections can be made. Many different methods have been proposed for in situ diameter measurement, including optical

Acceleration-based spindle monitoring based on geometric error motions

April 3, 2025
Author(s)
Aaron Cornelius, Gregory Vogl, Ryan Hall, Yongzhi Qu
The development of intelligent machine tools requires integrating sensors that allow the machine to monitor, diagnose, and control the machining process. However, existing sensors for monitoring tool vibrations are intrusive and difficult to integrate in a
