Effects of Cooling Systems on the Thermal Behaviour of Machine Tools and Thermal Error Models

open access: yesJournal of Machine Engineering, 2020
Today, cooling systems are increasingly applied to the structure of machine tools (MT). Unfortunately, to date there have been few efforts to precisely control these cooling systems, which inhibits the full utilisation of their potential to improve MT ...

Compensation of Static and Transient Thermal Errors on CMMs

open access: yesCIRP Annals, 2001
Abstract Using CMMs under normal workshop conditions necessitates to take into account the influence of environmental temperature on the machine structure. Non-standardised environmental conditions result in temperature dependent measurement errors.

Effects of mode degeneracy in the LIGO Livingston Observatory recycling cavity [PDF]

open access: yes, 2007
We analyze the electromagnetic fields in a Pound-Drever-Hall locked, marginally unstable, Fabry-Perot cavity as a function of small changes in the cavity length during resonance.
