Real-Time Compensation for Thermal Errors of the Milling Machine [PDF]
Applied Sciences (Switzerland), 2016 This paper is focused on developing a compensation module for reducing the thermal errors of a computer numerical control (CNC) milling machine. The thermal induced displacement variations of machine tools are a vital problem that causes positioning errors to be over than 65%.

Thermal and Geometric Error Compensation Approach for an Optical Linear Encoder [PDF]
Sensors, 2021 Linear displacement measuring systems, like optical encoders, are widely used in various precise positioning applications to form a full closed-loop control system. Thus, the performance of the machine and the quality of its technological process are highly dependent on the accuracy of the linear encoder used.

Thermal error modelling for real-time error compensation [PDF]
The International Journal of Advanced Manufacturing Technology, 1996 A modelling strategy for the prediction of both the scalar and the position-dependent thermal error components is presented. Two types of empirical modelling method based on the multiple regression analysis (MRA) and the artificial neural network (ANN) have been proposed for the reaLtime prediction of thermal errors with multiple temperature ...

Pre-Compensation of Thermal Error for Laser-Assisted Diamond Turning
Micromachines, 2023 The laser-assisted diamond turning (LADT) method can effectively improve the machinability of hard and brittle materials based on the laser heating effect, resulting in prolonged diamond tool life and better surface integrity. However, due to the incomplete absorption of laser beam energy within the workpiece cutting zone, simultaneous heating of the ...

Error compensation for thermally induced errors on a machine tool [PDF]
, 1996 Heat flow from internal and external sources and the environment create machine deformations, resulting in positioning errors between the tool and workpiece. There is no industrially accepted method for thermal error compensation. A simple model has been selected that linearly relates discrete temperature measurements to the deflection.

Neural network thermal error compensation of a machining center
Precision Engineering, 2000 Abstract A neural network based on Artificial Resonance Theory (ART-map) was used to predict and compensate the tool point errors of a 3-axis machining center using discrete temperature readings from the machine’s structure as inputs. A combination of kinematic error modeling, curve fitting, and the neural network were used to maintain the machine’s ...
