The significance of air pockets for modelling thermal errors of machine tools

, 2013
It is well known, especially with the prevalence of compensation for geometric errors, that thermal error represents the most significant proportion of the total volumetric error of the machine tool. Thermal error in machine tools originates from changes

Handling Ambient Temperature Changes in Characteristic Diagram Based Thermal Error Compensation

, 2022
S.131-138Thermal errors are one of the lead causes for positioning inaccuracies in modern machine tools. These errors are caused by various internal and external heat sources and sinks which shape the machine tool's temperature field and thus its ...
