Thermally induced errors have been significant factors affecting machine tool accuracy. In this paper, the thermal spindle error and thermal feed axis error have been considered, and a measurement/compensation system for thermal error is introduced. Several modelling techniques for thermal errors are also implemented for the thermal error prediction; i.

Errors of thermal-energy measurements
Measurement Techniques, 2000It is shown that systematic errors play a significant role in thermal-energy measurements while random errors are negligible. Algebraic summation of the error components is recommended for evaluation of the errors of heat meters; quadratic summation is recommended for evaluation of thermal-energy errors.

Errors in Thermal Measurements
Nature, 1932IN some recent investigations on adsorption1 it seems to have been established that erroneous conclusions have been reached on account of errors unsuspected by the experimenters and arising from the time lag of thermometric apparatus. Workers with experience in thermal measurements are well aware of the possibility of such errors, and in particular the

Spindle thermal error prediction approach based on thermal infrared images: A deep learning method
, 2021It is essential to precisely model the spindle thermal error due to its dramatic influence on the machining accuracy. In this paper, the deep learning convolutional neural network (CNN) is used to model the axial and radial thermal errors of horizontal ...

Thermal error of a hydrostatic spindle
Precision Engineering, 2011This paper proposes a thermo-mechanical error model of a hydrostatic spindle for a high precision machine tool. By predicting the variation of motion error induced by thermal effects on a machine worktable during machining, this model allows deeper insights into the underlying mechanisms that result in evolutions of the spindle accuracy. The heat power

Error of measurement of thermal energy
Measurement Techniques, 1998Analytical expressions are obtained for the error of measurement of thermal energy. It is shown that pairs of temperature transducers and flowmeters must be used to satisfy the “Regulations on the Metering of Thermal Energy and Flows of Heart Carriers”.

Error of measurement of thermal power
Measurement Techniques, 1995Formulas for calculating the errors of heat output measurement are refined on the basis of the relation between the partial errors of measurement of the mass flow of a heat-transfer agent and its thermal flux. Examples are given for steam and hot water.
