In the past, the models to do so have been parametrized using precise measurement equipment like lasertracers. However, these lasertracers cannot be used to measure the thermo-elastic error during cooling lubricant usage, which is necessary for most industrial applications. Therefore, this paper presents a method on how to measure the thermo-elastic machine behavior using Integral Deformation Sensors to compute the tool center point displacement during coolant usage based on a white box modeling approach. These computed displacements are then used to parametrize a correction model that uses low order delays elements.enThermal deformationThermo-elastic behaviorMachine toolsTool center pointCorrectionDDC::600 Technik, Medizin, angewandte Wissenschaften::620 Ingenieurwissenschaftenjournal article
