A Method for Thermal-Deformation Corrections of CMMs

CIRP Annals - Manufacturing Technology, 1990
Summary A method for the evaluation and the correction of thermal deformations of CMMs is presented; the method uses a deformation mathematical model based on continuous temperature and gradient functions: it follows an empiric approach and requires short time and cheap equipment to be applied.

Particular behavior of spindle thermal deformation by thermal bending

International Journal of Machine Tools and Manufacture, 2003
Thermally induced errors reduce the accuracy in precision machining, and a great deal of research has been presented on compensation for these errors in machine tools. However, during the transition period after commencing or stopping spindle rotation, thermal deformation behavior is very complex.

Deformable mirror with thermal actuators

Optics Letters, 2002
Low-cost adaptive optics is applied in lasers, scientific instrumentation, ultrafast sciences, and ophthalmology. These applications demand that the deformable mirrors used be simple, inexpensive, reliable, and efficient. We report a novel type of ultralow-cost deformable mirror with thermal actuators.
