Measurement, modeling and compensation of thermal error for machine tools
2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015Thermal error accounts for a large proportion in the error sources of the machine tool. In this paper, the thermal error of a boring and milling machine tool is modeled with the output error model of timing analysis. In order to improve the prediction accuracy, Firefly algorithm is used to optimize the number of groups and the orders of output error ...

Thermal error compensation method for machine center
The International Journal of Advanced Manufacturing Technology, 2011High-speed machining (HSM) technology has become the most important application in metal cutting industries. However, overcome the positioning error is one of a great concern. The position error happens due to poor machine structure design and thermal expansion comes from cutting, especially when HSM is applied.

Thermal Property Analysis of Precision Machinery and Its Thermal Error Compensation
International Journal of Heat and Technology, 2022The machining error caused by the thermal deformation of machines or tools accounts for half or even more in the total error, and the machining precision could be improved by stabilizing the heat balance of the process system. However, few of the existing studies have concerned about the thermal deformation law caused by the high-speed self-feed ...
