Abstract

In the field of precision machining thermal error is one of the main error sources in CNC machining. The thermal error compensation of CNC lathe can effectively improve the machining accuracy of machine tools. On the basis of the research of local thermal error compensation technology in NC lathe the temperature of the key points in CNC machining is real-time measured by platinum resistance temperature sensor. And the thermal error model is established by means of the fit of the measured temperature and linear regression theory. According to the thermal error model, the experiment of thermal error compensation is conducted, and the experimental results indicate that better surface quality is achieved with the implementation of the thermal error compensation.
